Sources and evidence
Every source HoneyHQ cites, what kind of source it is, and the rules that decide how much weight it can carry.
What a source type decides
A source's type is not decoration. A claim may only sit on the top tier — established evidence — if at least one systematic review, meta-analysis, regulatory guidance or clinical guidance document supports it. That makes the top tier structurally expensive to reach, which is the intent: a textbook and a producer's spec sheet are both useful and neither can promote a claim to the strongest tier on its own.
Why producer and retailer material is listed at all
Excluding it would be dishonest about where some information genuinely comes from — a packer's own specification is the best record of what they filter and to what. It is far better to cite it and let the type speak than to launder it into something anonymous.
HoneyHQ synthesis
A great deal of what a reference site says is editorial synthesis across a field rather than a restatement of one document. "Acacia honey stays liquid because it is fructose-dominant" is not a finding anybody published — it is the standard understanding assembled from several. Citing that to a fabricated paper would be a lie; citing it to nothing would hide it. So it is listed as what it is, and it can never carry a claim to the top tier.
The source list
HoneyHQ editorial synthesis
HoneyHQ synthesis · HEKNO Ltd
Standard understanding assembled across the field rather than taken from one document. Never the sole support for a claim rated as established evidence; the site's validation rules reject it in that position.

The Honey (England) Regulations 2015
Regulatory guidance · can support a top-tier claim · UK Government · 2015 · SI 2015/1348
The domestic implementation of the EU honey directive in England, with parallel instruments in Scotland, Wales and Northern Ireland. Retained after EU exit, so the compositional criteria still match the directive; later EU amendments do not flow through automatically.
The Honey (Scotland) Regulations 2015
Regulatory guidance · can support a top-tier claim · Scottish Government · 2015 · SSI 2015/208
Scotland's implementation of the EU honey directive, in force 24 June 2015. Amended only by EU-exit corrections (2019 and 2020 Scottish instruments); on 31 October 2026 legislation.gov.uk listed no outstanding effects, so the blend formulas remain as made.
The Honey (Wales) Regulations 2015
Regulatory guidance · can support a top-tier claim · Welsh Government · 2015 · WSI 2015/1507 (W. 174)
Wales's implementation of the EU honey directive, in force 3 August 2015. Amended only by a 2020 Welsh EU-exit instrument; on 31 October 2026 legislation.gov.uk listed no outstanding effects, so the blend formulas remain as made.
The Breakfast Foods (Amendment) Regulations (Northern Ireland) 2026
Regulatory guidance · can support a top-tier claim · Department of Health, Northern Ireland · 2026 · SR 2026/5
The Northern Ireland transposition of Directive (EU) 2024/1438, made 14 January 2026 and in operation from 14 June 2026. It amends the Honey Regulations (Northern Ireland) 2015. Territorial extent is Northern Ireland only, which is why it is the instrument that makes the GB/NI divergence concrete rather than predicted. Cited for the fact of the divergence, never as advice on compliance.
Masonry bees: technical advice
Industry body · Society for the Protection of Ancient Buildings · 2024
Building-conservation guidance on solitary bees in mortar, and the reason this site can state the damage question without either alarming or dismissing a reader. It is unusual in saying plainly that a few holes will not cause significant decay and that mortar bees are not generally as building-unfriendly as perceived, while also describing the conditions under which dense aggregations of an excavating species do matter. Cited for the building position; the entomology comes from the field-guide literature.
Wildlife and Countryside Act 1981
Regulatory guidance · can support a top-tier claim · UK Government · 1981 · 1981 c. 69
The governing statute for wild bird and bat protection in Great Britain, alongside the Conservation of Habitats and Species Regulations 2017. Cited on this site for one narrow and practical point: bats and their roosts and active birds' nests are protected where bees are not, and roof, soffit and cavity work is exactly where all three are found together. Not cited as advice on any particular situation, and not a claim about protection status for bees.

Honey for acute cough in children (Cochrane systematic review)
Systematic review · can support a top-tier claim · Cochrane Database of Systematic Reviews · CD007094
The main systematic evidence on honey and acute cough in children. Comparisons are against no treatment, placebo and specific antitussives; the review's own assessment of certainty is what the health section reports rather than the headline direction alone.
Cough (acute): antimicrobial prescribing (NG120)
Clinical guidance · can support a top-tier claim · National Institute for Health and Care Excellence · 2019 · NG120
Names honey among self-care options for acute cough in adults and children over one year. A guideline recommendation, not a claim of efficacy against disease.
Public health guidance on infant botulism and honey
Regulatory guidance · can support a top-tier claim · National food safety and public health agencies (UK, US, EU, Australia/NZ)
The advice not to give honey to infants under 12 months is consistent across national agencies. Cited as a body of concordant guidance rather than one document, because that concordance is the point.

Framework for interrogation of honey authenticity databases (IHAD)
Regulatory guidance · can support a top-tier claim · Government Chemist and Department for Environment, Food and Rural Affairs · 2025 · Defra project FA0198
The output of an expert working group chaired by Professor Michael Walker, commissioned under Defra's Food Authenticity Programme and jointly funded with the Government Chemist. Dated April 2025 and published 28 November 2025. It sets out how a proprietary authenticity database should be interrogated for scope, composition, metadata, representativity and method validation, and describes evaluative reporting as a way of stating the strength of analytical evidence. The document carries an explicit disclaimer that it represents the authors' views rather than government policy, which is how it is used here: as an authoritative account of method, not as a legal instrument.

Understanding honey fraud and the role of authenticity testing
Regulatory guidance · can support a top-tier claim · Government Chemist · 2026
A Government Chemist news item of 27 March 2026 summarising the current UK position: honey fraud remains high profile and contentious, sophisticated practices can evade detection, complex supply chains limit traceability, stakeholders disagree about the scale, and variation between testing methods together with the absence of harmonised approaches means the extent of fraud remains unclear. Cited for that characterisation of the state of play rather than for any prevalence figure, because it gives none. Accessed 2026-08-28.

Honey fermented garlic may be risky
Industry body · Kansas State University Research and Extension · 2020
Extension food-safety advice on garlic held in honey. The useful part is the mechanism rather than the verdict: garlic is a low-acid food with high water activity, honey's pH is variable and its protective property is low water activity, and the interface between clove and honey is where that protection stops applying. Not a validated process and not regulatory guidance — cited for why no shelf-life claim can be made.
How hot honey reached restaurant menus
News article · Restaurant Business · 2023
Trade-press account of the commercial category's origin: a chilli-honey encountered at a Brazilian pizzeria in 2004, made domestically, and put on a Brooklyn pizzeria menu in 2010, from which the packaged product and the wider sweet-heat menu trend followed. Cited for the commercial chronology only. Chilli-in-honey as a domestic practice is much older and separately attested.

Widespread exploitation of the honeybee by early Neolithic farmers
Peer-reviewed article · Nature · 2015
Lipid residue analysis of several thousand Neolithic potsherds across Europe, the Near East and North Africa, establishing the broad early distribution of beeswax use and an ecological northern limit. The paper is careful that a beeswax signature records contact with the material, not beekeeping, and not honey specifically.
It is the land of honey: beekeeping at Tel Rehov

Reciprocal signaling in honeyguide-human mutualism
Peer-reviewed article · Science · 2016
Playback experiment with Yao honey hunters in Mozambique: the traditional call more than doubled the probability of being guided compared with control sounds of similar acoustic structure. The design is what makes this a demonstration rather than an observation.
Culturally determined interspecies communication between humans and honeyguides
Peer-reviewed article · Science · 2023
Cross-regional playback showing that birds respond most strongly to the signal used by the local human community. Evidence that the birds learn a local convention rather than responding to human sound in general.
Mutualism and manipulation in Hadza-honeyguide interactions
Peer-reviewed article · Evolution and Human Behavior · 2014
Quantifies the honey fraction of the Hadza diet and the contribution of guided finds, and records that these hunters deliberately do not reward the bird — which is the counter-example that keeps the reciprocity account honest.
The Mind of a Bee
Monograph · Princeton University Press · 2022
The current synthesis of the cognition and sensory literature by one of the field's principal investigators, and unusually careful about the limits of its own results.

Configural processing enables discrimination and categorization of face-like stimuli in honeybees
Peer-reviewed article · Journal of Experimental Biology · 2010

Numerical ordering of zero in honey bees
Peer-reviewed article · Science · 2018
Reports bees placing an empty stimulus at the low end of a learned quantity order. Whether the behaviour reflects a numerical representation or a response to correlated low-level cues such as area and edge length is exactly what is unresolved, and the paper's own controls are the subject of the argument.
Numerical cognition in honeybees enables addition and subtraction
Peer-reviewed article · Science Advances · 2019
A single study reporting above-chance performance on a symbolic addition and subtraction task. Not independently replicated at the time of review, and challenged on whether the design excludes simpler explanations. HoneyHQ reports the study and does not report its conclusion as a fact.
Bumblebees show cognitive flexibility by improving on an observed complex behavior
Peer-reviewed article · Science · 2017
Bumblebees trained to move a ball to a target for reward, and improving on the demonstrated solution rather than copying it. Bombus terrestris, not Apis mellifera.
Associative mechanisms allow for social learning and cultural transmission of string pulling in an insect
Peer-reviewed article · PLOS Biology · 2016
String pulling acquired by observation and then spreading through a colony. The title's own framing — associative mechanisms — is the point: social learning here does not require imitation in any rich sense.
Bumblebees acquire alternative puzzle-box solutions via social learning
Peer-reviewed article · PLOS Biology · 2023
Seeded solutions spread and persist within colonies, with populations retaining the variant they were shown. Whether that meets a given definition of culture is a definitional argument rather than an experimental result.
Do bumble bees play?
Peer-reviewed article · Animal Behaviour · 2022
Bumblebees rolling wooden balls with no food reward, more when young, and choosing to enter a chamber containing them. Meets several published behavioural criteria for play; says nothing about whether it is enjoyed.
Agitated honeybees exhibit pessimistic cognitive biases
Peer-reviewed article · Current Biology · 2011
A judgement-bias paradigm — the standard animal-welfare design — showing that shaken bees classify ambiguous stimuli more negatively. Evidence of an internal state that biases decisions, not of felt experience.
Unexpected rewards induce dopamine-dependent positive emotion-like state changes in bumblebees

Motivational trade-offs and modulation of nociception in bumblebees
Peer-reviewed article · Proceedings of the National Academy of Sciences · 2022
Bumblebees accept a noxiously hot feeder for a higher sugar reward, which is a trade-off rather than a reflex and is one criterion used in pain research. Nociception is established; pain as experience is not addressable by this method.

Sleep deprivation impairs precision of waggle dance signaling in honey bees
Peer-reviewed article · Proceedings of the National Academy of Sciences · 2010
Sleep-deprived foragers signal direction less precisely the following day. A social cost to poor sleep in an insect, and one of the clearest functional demonstrations that insect sleep is sleep.
Non-numerical strategies used by bees to solve numerical cognition tasks
Peer-reviewed article · Proceedings of the Royal Society B: Biological Sciences · 2021 · 10.1098/rspb.2020.2711
The named, peer-reviewed critique of the bee numerical-cognition work. Re-examines the zero-ordering experiments, argues the choices track continuous visual properties — spatial frequency, edge length, convex hull — rather than number, and reproduces the reported behaviour with a nine-neuron model containing no numerical representation. Answered by Zanon and colleagues in 2026; both belong on the page.
Stimuli that fit: a biology-aligned approach to numerical cognition research
Peer-reviewed article · Proceedings of the Royal Society B: Biological Sciences · 2026 · 10.1098/rspb.2025.3057
The published reply. Argues that analyses excluding the low spatial frequencies relevant to bee vision introduce spurious correlations between visual features and number, and that recalculating stimulus properties across the spectrum a bee actually resolves leaves a residual sensitivity to numerosity. TWO THINGS TO KEEP ATTACHED TO THIS CITATION: it is a reanalysis of stimulus properties rather than a new experiment, and several of the authors of the original studies are among its authors. It is a reply in a live argument, not an independent adjudication of it.

The Hive and the Honey-Bee (L. L. Langstroth)
Historical text · Northampton, Massachusetts · 1853
Langstroth's own account, published the year after his patent. THE REASON IT IS CITED AS A PRIMARY TEXT AND NOT AS HISTORY: it is where he sets out the bee-space principle and the hive built on it, and it is also an interested party's account of his own priority. What it establishes is what Langstroth claimed and when; who first observed the spacing, and who built movable frames before him, are questions for the secondary literature.
Importance of pollinators in changing landscapes for world crops
Peer-reviewed article · Proceedings of the Royal Society B: Biological Sciences · 2007 · 10.1098/rspb.2006.3721
Read in its PMC full text on 31 October 2026; the electronic supplementary appendix itself was not retrievable. The main text names the 13 crops for which animal pollination is essential for most varieties (atemoya, Brazil nut, cantaloupe, cocoa, kiwi, macadamia, passion fruit, pawpaw, rowanberry, sapodilla, squashes and pumpkins, vanilla, watermelon) and the seven that showed no increase (chickpea, peas, lentil, olive, pepper, quinoa, grapes); it excluded crops whose seed is used only to grow vegetable parts or forage; and for cocoa, among others, honey bees were not mentioned as pollinators. The crop-by-crop assessment of animal pollination dependence that almost every later figure rests on. Its own finding is carefully bounded: most leading global crops by volume — the cereals — do not depend on animal pollination at all, while a large number of crops contributing to dietary diversity depend on it to varying degrees. Cited for the dependence classification, not for a monetary total.
Economic valuation of the vulnerability of world agriculture confronted with pollinator decline
Peer-reviewed article · Ecological Economics · 2009 · 10.1016/j.ecolecon.2008.06.014
Ecological Economics 68(3):810–821 (Gallai, Salles, Settele and Vaissière). Abstract as quoted in the authors' and publisher's records, checked 2 November 2026: the total economic value of insect pollination worldwide was €153 billion in 2005, 9.5% of the value of world agricultural production used for human food, with vegetables and fruit about €50 billion each; a separate consumer-surplus loss of €190–310 billion for price elasticities of –1.5 to –0.8. Press coverage at the time restated it as about $216 billion, a conversion the paper does not make. Crops for livestock feed, biofuel and ornamentals, and wild-plant pollination, are outside it. The source of the widely quoted global pollination value figure. CITE IT WITH ITS METHOD OR NOT AT ALL: the number is the estimated market value of the share of crop production attributable to animal pollination in a single reference year, computed from dependence ratios and prices. It is not the sum bees earn, not what would be lost if pollinators vanished, and the authors say so — a total-loss scenario would change prices, which the method holds fixed.

The systematic evidence on instrumented hives. HoneyHQ held this whole subject back at first because vendor material dominated the accessible literature; this review and its 2025 successor are what made it writable. ITS OWN CENTRAL FINDING IS THE CAUTION: most published work is proof-of-concept, over short deployments in controlled conditions, and generalisability is the standing weakness of the field.
Buzzing with Intelligence: A Systematic Review of Smart Beehive Technologies
Systematic review · can support a top-tier claim · Sensors · 2025 · 10.3390/s25175359
Šabić, Perković, Šolić and Šerić. Reviews 135 peer-reviewed publications (93 journal articles, 42 conference papers) indexed from 1990 to April 2025. Environmental sensing appears in 66 studies, acoustic or vibration in 52, imaging in 49, weight in 34, bee counters in 13, air composition in 10; 55% used a single sensor type. Weight is 'generally more associated with food reserves than with disease'. True multimodal fusion 'remains largely absent', many systems are still prototypes, long-term multi-seasonal field testing is missing, and solar-powered hives 'often fail to harvest sufficient energy for continuous monitoring'. Temperature readings vary with probe position. Full text read in part.

The invasion, provenance and diversity of Vespa velutina Lepeletier (Hymenoptera: Vespidae) in Great Britain
Peer-reviewed article · PLOS ONE · 2017 · 10.1371/journal.pone.0185172
Genetic work on the first British incursions, establishing that the European population traces to a single introduction into south-west France and that British finds derive from it. Cited for provenance and for the low genetic diversity of the invasive population, not for current distribution.
First report of established mite populations, Tropilaelaps mercedesae, in Europe
Peer-reviewed article · Journal of Apicultural Research · 2024 · 10.1080/00218839.2024.2343976
Infestations in the Krasnodar region of western Russia, identified genetically as T. mercedesae, with mites overwintering locally. The paper that moved Tropilaelaps from an Asian problem to a European one, and the reason the status table on this site separates established from detected.

A giant honey bee swarm carrying 28 T. mercedesae mites, detected on a vessel inbound to Port Elizabeth, New Jersey. The documented case that makes 'intercepted' a distinct category from 'detected' on this site, and the clearest illustration of the movement pathway.
Insights from U.S. beekeeper triage surveys following unusually high honey bee colony losses 2024-2025
Peer-reviewed article · Science of the Total Environment · 2025 · 10.1016/j.scitotenv.2025.180650
The peer-reviewed account of the 2024-25 US losses: commercial operations losing more than smaller ones for the first time, varroa most frequently cited by respondents, and — importantly — no significant difference in losses between amitraz users and non-users. Cited as much for that last finding as for the loss figures, because it is what restrains the simplest causal story.
Sensitivity and Resistance of Parasitic Mites (Varroa destructor, Tropilaelaps spp. and Acarapis woodi) Against Amitraz and Amitraz-Based Product Treatment: A Systematic Review
Systematic review · can support a top-tier claim · Insects · 2025 · 10.3390/insects16030234
Seventy-four studies on amitraz sensitivity. Establishes that resistance is real, documented in several countries and highly variable between apiaries rather than uniform across regions, and records that evidence on Tropilaelaps sensitivity is almost absent — one field study.
USDA researchers find viruses from miticide-resistant parasitic mites in collapsed colonies
News article · United States Department of Agriculture, Agricultural Research Service · 2025
An agency news release describing screening results over a manuscript then in review. Carried on this site as a watch signal and nothing more: a press release announcing a finding is not the finding, and this one states a causal conclusion that the peer-reviewed survey work does not yet support.
UK Biodiversity Indicator D1c: status of pollinating insects
Government statistics · Joint Nature Conservation Committee and Defra · 2026
Official statistics published 5 January 2026 covering data to 2024: an occupancy index across 393 wild bee and hoverfly species. Measures distribution — the number of 1 km squares a species is recorded in — and not abundance, which is the distinction that governs how it may be quoted.

Interview-based study of Awer honey hunters in the Boni forest of coastal Kenya, recording the snail-shell whistle used to summon honeyguides, how the skill is transmitted, and the guiding that leads to honey bee nests only. The published basis for treating Awer practice as its own tradition rather than as an appendix to the Boran and Yao work.
Understanding the Livelihood Implications of Reliable Honey Trade in the Miombo Woodlands in Zambia
Peer-reviewed article · Frontiers in Forests and Global Change · 2020 · 10.3389/ffgc.2020.00028
The bark-hive economy of north-western Zambia measured as a livelihood: hive numbers, yields, buyer relationships and what a dependable market does to the practice. Useful precisely because it treats miombo beekeeping as an economy rather than as a survival.
Traditional knowledge of Korean native beekeeping and sustainable forest management
Peer-reviewed article · Forest Policy and Economics · 2012 · 10.1016/j.forpol.2011.12.003
Field survey of tobong beekeeping — Apis cerana in mountain villages of the Republic of Korea — covering hive construction, the single autumn harvest and the relationship between the practice and forest management. The source that lets the Korean record say something specific rather than gesture at a long history.
De re coquinaria (Apicius)
Historical text · Compiled in its surviving form in the fourth or fifth century CE
The largest surviving body of Roman recipes, and the reason Roman honey cookery can be described rather than inferred. TWO CAUTIONS: the collection is later than the authors whose names attach to it, and it records elite kitchen practice, so it is evidence for what was cooked in some Roman kitchens and not for what most people ate.
Naturalis Historia (Pliny the Elder)
Historical text · Rome, completed around 77 CE
Books XI and XXI carry the fullest classical account of bees, honey and wax, including grades of honey, harvesting seasons and medical uses. Pliny compiles rather than observes, repeats claims he cannot check, and says so more often than he is given credit for — his value is as a record of what was believed and traded, not as natural history.
De re rustica (Columella)
Historical text · Rome, first century CE
Book IX is the most practical surviving Roman treatment of beekeeping: hive materials, siting, harvesting fractions and the economics of an estate apiary. Read as an agronomist's prescription for a profitable estate rather than as a description of ordinary practice.
The Qur'an, Surat an-Nahl (The Bee), 16:68-69
Historical text
The two verses in which the bee is instructed to take from the fruits and from which a drink of varied colours issues containing healing for people. Cited as scripture — the basis of an enduring religious and dietary attitude to honey — and never as evidence of therapeutic effect, which is assessed on the health pages against clinical sources.
The Exsultet (Easter Proclamation), Roman Missal
Historical text
The Easter vigil proclamation, which praises the work of bees in blessing the paschal candle. The clearest single text behind the Western church's preference for beeswax, and the reason liturgical demand shaped medieval beekeeping. Its wording varies between recensions, and the bee passage is longer in some than in others.
Relación de las cosas de Yucatán (Diego de Landa)
Historical text · Written around 1566; surviving in a later abridged copy
The fullest colonial description of Yucatec Maya beekeeping and of the ceremonies attached to it. AN AWKWARD SOURCE AND THE PAGE SAYS SO: Landa was the Franciscan who ordered the destruction of Maya books, he wrote as an interested party, and what survives is an abridgement made by another hand. Valuable, and not a neutral witness.
The Madrid Codex (Codex Tro-Cortesianus), bee almanacs
Historical text · Postclassic Maya, probably fifteenth or sixteenth century
Around a dozen pages of almanacs showing beekeeping and stingless-bee imagery, the largest surviving pre-conquest source on the subject. Readings of individual scenes and of the deities in them are scholarly interpretation and are contested in detail; the presence of an extended beekeeping section is not.
Honey as a topical treatment for wounds (Cochrane systematic review)
Systematic review · can support a top-tier claim · Cochrane Database of Systematic Reviews · 2015 · 10.1002/14651858.CD005083.pub4
The canonical systematic evidence on topical honey for wounds. Cited on this site for what it actually concludes — that the evidence is of generally low quality and differs sharply by wound type, with partial-thickness burns the one area where it is least unfavourable — rather than for the headline that honey heals wounds.
Georgics, Book IV (Virgil)
Historical text · Rome, completed around 29 BCE
The fullest poetic treatment of bees in Latin literature, including the Aristaeus narrative and the bugonia. LITERATURE, NOT APICULTURE: Virgil is writing a poem with a political and philosophical argument, his bees are an image of a society, and where he describes practice he is not describing what he watched. Cited for what Romans wrote about bees, never for what bees do.
The Prose Edda (Snorri Sturluson)
Historical text · Iceland, around 1220
The fullest surviving account of the mead of poetry. TWO CAUTIONS THAT BELONG WITH EVERY CITATION: Snorri wrote two centuries after Iceland's conversion, as a Christian antiquarian systematising material he received in fragments, and his tidiness is his own. It is the best source there is and it is not a transcript of pre-Christian belief.
Homeric Hymn to Hermes
Historical text · Archaic Greece, probably sixth century BCE
Contains the passage on three prophetic female figures fed on honeycomb, conventionally identified with the Thriae. The identification and even the reading of the passage are debated; it is cited here as an early Greek association between honey and prophetic speech, which is what it securely supports.

The systematic evidence on bee venom therapy, covering both what the trials show and what harms they report. Cited on this site for the adverse-event picture — adverse events are common and anaphylaxis is among them — and not as support for any therapeutic indication.
Uncorking the Past: The Quest for Wine, Beer, and Other Alcoholic Beverages
Monograph · University of California Press · 2009
Biomolecular archaeology of fermented drinks, including the Jiahu residues combining honey, rice and fruit. The reason claims about the antiquity of fermented honey can be stated from residue chemistry rather than from assertion — and also the reason 'the oldest alcoholic drink' is not a question the evidence answers cleanly, since mixed drinks precede any pure category.
Beeswax: Production, Properties, Composition and Control
Monograph · Bee Product Science · 2016
Working reference on wax composition, its physical behaviour, and the adulteration problem in foundation wax. Cited for the material properties that explain why beeswax was chosen for candles, casting, sealing and resist dyeing rather than for the history of those uses.

Tropilaelaps: parasitic mite of honey bees (advisory leaflet)
Regulatory guidance · can support a top-tier claim · Animal and Plant Health Agency, National Bee Unit · 2026
The statutory authority's current account: four recognised species, two adapted to Apis mellifera; T. mercedesae reported in European Russia in 2024 and confirmed in Georgia, suspected in Uzbekistan, Tajikistan, Crimea, Belarus and Azerbaijan (map current to December 2025); not present in the UK; notifiable; exotic-pest surveillance since 2003 and sentinel apiaries. Also the source for two biological points that revise older accounts — that the mite can feed on open brood, and that broodless periods 'do not seem to limit its spread', with the overwintering mechanism unexplained.
Geographical spread of the exotic mite Tropilaelaps spp.: state of play of the worldwide situation in March 2025

The EU reference laboratory's country-by-country table as at 14 March 2025, and its statement that the EU is free and that the infestation is listed in categories D and E under Regulation (EU) 2018/1882. Useful precisely because it disagrees with the UK leaflet on Uzbekistan and Azerbaijan — this dataset records the disagreement rather than choosing. Notes itself that few events are reported to WOAH and most data derive from research projects.
High risk of spreading of Tropilaelaps mercedesae in Eastern Europe, after new detection in Turkey
Industry body · Apimondia · 2026

Hive-stored pollen of honey bees: many lines of evidence are consistent with pollen preservation, not nutrient conversion
Peer-reviewed article · Molecular Ecology · 2014 · 10.1111/mec.12966
University of Arizona and USDA-ARS Carl Hayden Bee Research Center. Bees preferentially ate pollen stored under three days; bacteria were few in fresh pollen and fell after 96 hours of storage; fresh and stored pollen carried the same bacterial community; the microbe-to-grain surface ratio was about 1:1,000,000; stored grains were not degraded. Concludes stored pollen is a preservative environment, not one of microbial nutrient conversion — the evidence behind treating 'bee bread is fermented' as contested.
Gut microbial communities of social bees

Routes of acquisition of the gut microbiota of the honey bee Apis mellifera
Peer-reviewed article · Applied and Environmental Microbiology · 2014 · 10.1128/AEM.01861-14
Newly emerged workers have no gut bacteria and gain characteristic communities within 4–6 days in the hive. Typical communities formed only with nurse workers or their faeces present; trophallaxis or hive materials alone (comb, honey, bee bread) produced atypical communities. Snodgrassella, Gilliamella and Frischella depended on nurses or hindgut material.
Honeybee gut microbiota promotes host weight gain via bacterial metabolism and hormonal signaling
Peer-reviewed article · Proceedings of the National Academy of Sciences · 2017 · 10.1073/pnas.1701819114
Bees with their gut microbiota gained more weight than those without, likely through vitellogenin, insulin signalling and taste response; the bacteria produce short-chain fatty acids, lower gut pH and appear to break down plant polymers from pollen into metabolites that reach the bee's blood.

Tools for Varroa Management: A Guide to Effective Varroa Sampling & Control, Ninth Edition
Regulatory guidance · can support a top-tier claim · Honey Bee Health Coalition (Keystone Policy Center) · 2026 · HBHC Tools for Varroa Management, 9th edition, 11 June 2026
Written for beekeepers in the United States and Canada. Sampling by alcohol or soap wash (recommended) or powdered-sugar shake of about 300 adult bees, about half a cup; result as mites per 100 adult bees. Table 1 gives thresholds by colony phase: dormant and population increase, control promptly at 1% or more; peak population and population decrease, at 2% or more. The guide calls these conservative estimates, 'an evolving science' and 'often situationally and regionally specific', and asks beekeepers to consult a local inspector or extension service. A sample of 0% does not mean no mites; sampling during population increase tends to underestimate risk; a sticky board shows a trend, not a per-bee load; mites seen on adult bees usually mean the load is already well over threshold.

Nosema apis and N. ceranae infect the lining of the adult bee's midgut. Most infected colonies look normal even when infection is heavy enough to cost honey production and pollination; brown faecal marks appear only in some acute cases; confirmation is by spores under the microscope at ×400 or by PCR, which is also the only way to tell the species apart. Spores can be confused with Malpighamoeba cysts and yeasts. The chapter keeps the Nosema names; the renaming dispute is cited separately.

Egg to adult in 3–12 weeks; larvae feed for about two weeks, then pupate in soil. Larval feeding goes with fermentation of stored honey, slime trails, comb collapse and absconding; worse in warm, humid conditions; extracting rooms are at risk; low-level reproduction can be cryptic.

Mites ingest haemolymph and fat body. Reproduction in brood cells just before capping: the first egg is male, then up to five or six females at about 30-hour intervals; two to three mated daughters per drone cell and one to two per worker cell, with drone brood preferred. Vectors deformed wing virus, acute and Israeli acute paralysis viruses and Kashmir bee virus; replication inside the mite is shown for DWV. Untreated colonies collapse in one to four years. 'At the global level, the damage threshold… cannot be established'; the regional estimates it quotes are examples, not standards. Natural mite fall and bee or brood examination are reliable only at medium to high infestation.

Wasps (National Bee Unit fact sheet)
Regulatory guidance · can support a top-tier claim · Animal and Plant Health Agency, National Bee Unit · 2026
Fact sheet dated September 2026, Crown copyright under the Open Government Licence. Seven UK vespids can prey on colonies: the common, German, red, tree, Norwegian and median wasps and the European hornet. Social wasps feed their young mainly on insects and are 'of vital importance to the ecosystem'; trapping risks killing beneficial insects and is unlikely to be effective. Predation can start in July in a good wasp year, is usually noticeable from August and declines from late September; some species kill bees and rob honey and pollen, and a sustained attack can weaken a colony past survival. The European hornet 'usually only predates on colonies to a small degree'. Recommends reduced entrances, robbing screens, careful feeding and keeping colonies strong. Gives worker lengths of about 25 mm for the yellow-legged hornet and about 30 mm for the European hornet, and the email alertnonnative@ceh.ac.uk alongside the app and form.

An evaluation of the costs of pest wasps (Vespula species) in New Zealand
Monograph · Department of Conservation and Ministry for Primary Industries, New Zealand (MacIntyre and Hellstrom) · 2015
Economic evaluation of the invasive common and German wasps. Both kill bees and larvae for protein and rob honey. Earlier surveys put hives destroyed or seriously affected at 1.9% destroyed and 4.9% affected in 1974/75 (Walton and Reid) and 8.13% and 9.35% destroyed or seriously affected in 1985/86 and 1986/87 (Clapperton and others, who thought their figures might be overestimates). A 2014 survey of 101 National Beekeepers Association members fed a modelled direct apiculture cost of NZ$8.8 million a year. Notes that reduced entrances lower hive losses but also depress honey yield. Bees were estimated to harvest 3.6% of the beech-forest honeydew.

At least 50 bees suffice for the standard tests; put them in a cardboard box, not a plastic bag, and freeze them if they cannot be sent at once. Do not collect samples where fumigants are suspected. The NBU screens for disease within 48 hours; the bees then pass to the Wildlife Incident Unit to await acceptance, and Natural England discloses the pesticide results.

Bee poisoning incidents in Germany in spring 2008 caused by abrasion of active substance from treated seeds during sowing of maize
Observational study · Julius-Kühn-Archiv 423 (Pistorius, Bischoff, Heimbach and Stähler; Julius Kühn-Institut) · 2009
Account by the federal examination centre for bee poisoning. More than 11,500 colonies of about 700 beekeepers in the Upper Rhine valley showed signs of insecticide poisoning in late April and May 2008: dying bees with cramping, disoriented behaviour and abnormal wing movements in front of and inside hives, up to several thousand dead a day, with mortality raised for weeks. Damage ranged from 10 to 90% and total colony losses were few; some communities had none. Dust abraded from clothianidin-treated maize seed (up to 80 g per 100,000 kernels in some batches) was blown out by pneumatic drills. Residue analysis of dust, plants, bees, fresh pollen and bee bread confirmed clothianidin, and bee samples were screened for varroa, Nosema and amoebae with no correlation to pathogens. Above-average winter losses of up to about 40% had been recorded in the region before the incidents.
Sensitivity of current Tropilaelaps mercedesae monitoring methods in Apis mellifera colonies
Peer-reviewed article · Scientific Reports 16 (Tokach, Aurell, Chuttong and Williams) · 2026 · 10.1038/s41598-026-46467-0
Field trial in 26 infested colonies at Chiang Mai University, Thailand, over ten days in late January 2024, with 200-cell brood uncapping as the reference. Share of colonies in which each method found Tropilaelaps: sticky board under the colony for about 70 hours with no miticide, 100%; worker brood uncapping (200 cells), 92.3%; brood-frame bump test, 73.1%; alcohol wash of about 300 bees, 38.5%; powdered sugar shake, 34.6%. Uncapping fewer cells found fewer infested colonies (85% at 100 cells). The authors conclude that methods effective for varroa will not reliably find Tropilaelaps.

Published 6 August 2025, updated 14 April 2026. States that carbon isotope analysis, standardised as AOAC 998.12, can detect adulteration with C4 sugars at levels of 7% or more and cannot detect syrups from C3 plants; that a liquid-chromatography step lets individual sugars be analysed and lower levels detected; and that syrups matching honey's isotopic composition are on the market and cannot be detected by isotope analysis. Points to the Commission's work towards validated DNA-sequencing methods.

Published 19 August 2025, updated 10 October 2025. Distinguishes direct adulteration — syrup added to honey, increasingly with syrups made to mimic honey's sugar composition — from indirect adulteration by feeding sugar syrups to bees during the main nectar flow, which it calls extremely difficult to detect; correct beekeeping practice should ensure feeding does not adulterate honey.

Published 4 August 2025, updated 27 August 2025. The 2015–2017 coordinated control plan took 2,264 samples from every EU member state plus Norway and Switzerland; samples passing first-tier purity checks and a sugar profile went to isotope analysis, and around 14% were suspicious of added sugar. The 2021–2022 action took 320 samples at EU borders with a wider set of methods (EA/LC-IRMS, HPAEC-PAD, LC-HRMS, 1H-NMR). Uses 'suspicious' throughout.
EU coordinated action 'From the Hives' (honey 2021–2022)

Sampling November 2021 to February 2022; 320 samples, 147 (46%) suspicious, a sample being suspicious when at least one marker of extraneous sugar was detected. The techniques gave presence or absence of markers, so the level of syrup could not be estimated. The JRC methods 'have proved useful in identifying suspicions of fraud but are yet to be validated'; the Commission had not adopted compliance methods. 44 EU operators investigated; the page gives seven sanctioned in one place and nine in another. The 2015–2017 plan found at least 14% not conforming.

A review of honey's inorganic composition: it reflects the environment the plants grow in and each plant's bioaccumulation; tools and galvanised storage can add iron and zinc; too few comparable studies exist for many honeys; inorganic content was less effective at discriminating geographical origin than botanical.
Orchard pollination: pollinizers, pollinators, and weather
Field guide · Penn State Extension (R. Crassweller) · 2026
Updated 12 January 2026. Defines a pollinizer as a compatible cultivar that supplies pollen — 'not to be confused with a pollinator, which is a bee'. Pollinizer and main-variety bloom must overlap; nearer pollinizers are better. The effective pollination period runs from about 3 to 12 days depending on cultivar, Delicious among the shortest, and pollination must happen within about 2 to 4 days of opening. In Pennsylvania terms: honey bees fly at about 65°F, bumble bees and solitary bees at 5 to 10 degrees lower; pollen may not germinate below 41°F and tubes grow very slowly below 51°F. Only about 2 to 8% of apple flowers and 3 to 11% of pear flowers need to set; sweet cherry needs 20 to 60%, sour cherry 20 to 75%. Gives no hive stocking rate.

Pollination requirements for various fruits and nuts
Field guide · Penn State Extension (R. Crassweller) · 2024
Updated 5 January 2024. Apple always needs another variety; pear mostly needs a pollinizer, a few varieties being self-fruitful and still cropping better with one; most sweet cherries are self-unfruitful, with self-fruitful cultivars such as Lapins, Stella, Sweetheart, Whitegold and Blackgold; commercial tart cherries are self-fruitful; almond must be pollinated by a different variety; blueberry is partially self-fruitful and cross-pollination improves fruit set and crop size.

Orchard pollination: wild bees
Field guide · Penn State Extension (D. J. Biddinger) · 2026
Updated 13 January 2026. At least 120 native bee species found in orchards in Penn State, Cornell and Pennsylvania Department of Agriculture surveys. Early-spring wild bees forage in cool, cloudy conditions when honey bees are less active. Most orchard bees nest in the ground, in bare well-drained soil, and almost entirely in fence-rows and woodlots beside orchards rather than in them; most non-bumble bees forage within about 100 yards of their nests. Larger blocks surrounded by cropland need flower strips, and honey bees can fill gaps.
Pollination of blueberry crops in Pennsylvania
Field guide · Penn State Extension (M. López-Uribe, K. Demchak, S. Fleischer and others) · 2025
Updated 13 January 2025. Poricidal anthers need sonication; the pollen is sticky and not moved by wind. Duke and Bluejay need no cross-pollination; Elliott, Bluecrop and Legacy benefit from it; self-pollination often gives lighter fruit. Cites Javorek et al. (2002): about 11 pollen grains per honey bee visit against about 45 for wild bees. On three small central-Pennsylvania farms over two years, roughly three bumble bee queens were seen for every honey bee. States that 'pollination by honey bees alone is not enough to achieve maximum yield', and that honey bees are still crucial on large commercial acreages. No stocking rate.

Pollination services in cucurbits
Field guide · Penn State Extension (S. Fleischer, E. Treanore, C. McGrady, J. P. Strange)
A recorded presentation; no date on the page. In 24 Pennsylvania wholesale pumpkin fields over three years, honey bees, squash bees and bumble bees made 97% of visits. Each group alone delivered more pollen than the threshold needed; flowers open for about four hours in the morning and close when it gets hot. Squash bees (Eucera pruinosa, formerly Peponapis) nest 5 to 9 inches deep in the soil; a Maryland and Virginia study found about three times the squash bee visitation on no-till farms. No hive rate.
Bee pollination of cucurbit crops (G1754)
Field guide · University of Nebraska–Lincoln Extension (L. Hodges, F. Baxendale) · 2007
Issued October 2007. Cucurbits carry male, female and in some crops combined flowers; melon and cucumber pollen is large and sticky and needs insects; an unpollinated flower aborts after its one day open, and poor pollination gives small or misshapen fruit. Gives, for Nebraska growers in 2007, at least 9 honey bee visits per cucumber flower and at least one strong hive per acre — recorded here as a dated regional recommendation, not a current one.

What are those avocado flowers doing, and what is doing it to them?
Field guide · University of California Agriculture and Natural Resources, Topics in Subtropics (B. A. Faber) · 2017
7 April 2017. Each avocado flower opens first as female, closes, and reopens as male (synchronous dichogamy), complicated by A and B flower types. But in California orchards a flower may stay female for days with no male flower nearby, or the reverse, so the textbook schedule does not guarantee transfer. Visitors include honey bees, native bees, hover flies, other flies, wasps and thrips; cool weather and competing flowers may keep honey bees off the trees.

L. A. Garibaldi and 49 co-authors. Abstract read. Across 41 crop systems worldwide, fruit set rose with wild-insect visitation everywhere but with honey bee visitation in only 14% of systems; an increase in wild-insect visits raised fruit set twice as much as the same increase in honey bee visits; the two acted independently, so honey bees supplemented rather than substituted for wild insects.

Insect pollination enhances seed yield, quality, and market value in oilseed rape
Peer-reviewed article · Oecologia 169: 1025–1032 · 2012 · doi:10.1007/s00442-012-2271-6
R. Bommarco, L. Marini, B. E. Vaissière (Swedish University of Agricultural Sciences). Abstract read. Ten fields of one spring oilseed rape cultivar; bagging experiments: insects raised seed weight per plant by 18% and market value by 20%, giving heavier seeds with more oil and less chlorophyll. Wild insects were more abundant in complex landscapes but yield did not differ, probably because honey bees pollinated consistently across fields. The abstract names no region; the authors work in Sweden.

S. S. Greenleaf, C. Kremen. Abstract read. In hybrid sunflower seed fields, encounters with wild bees made honey bees up to five times more efficient, effectively doubling honey bee pollination on the average field; this indirect effect was more than five times the wild bees' direct contribution. Proximity to natural habitat and planting practice both mattered.

Pollinating bees (Hymenoptera: Apiformes) of U.S. alfalfa compared for rates of pod and seed set
Peer-reviewed article · Journal of Economic Entomology 95(1): 22–27 · 2002 · doi:10.1603/0022-0493-95.1.22
J. H. Cane (USDA ARS). Abstract read. Alfalfa flowers must be tripped by a visiting bee to be pollinated. In a greenhouse comparison of single visits, a tripped flower had the same chance of pod and seed set whichever bee tripped it, so efficiency came down to the share of visited flowers tripped: female alkali bees 81%, female leafcutting bees 78%, males 61% and 51%, honey bees 22%. Field tripping data support the ranking.
Pollinator identity and behavior affect pollination in kiwifruit (Actinidia chinensis Planch.)
Peer-reviewed article · PeerJ 10: e12963 · 2022 · doi:10.7717/peerj.12963
M. A. Broussard and others (Plant & Food Research, New Zealand). Abstract read. Kiwifruit is functionally dioecious: insects must move pollen between separate male and female plants. In New Zealand orchards ('Hayward' and 'Zesy002'), honey bees were the most frequent visitors; Leioproctus and Bombus bees and the hover flies Helophilus hochstetteri and Eristalis tenax deposited similar amounts of pollen per visit.
Artificial pollination of kiwifruit results in greater fruit set compared to flowers pollinated by managed bees
Peer-reviewed article · Journal of Economic Entomology 116(3): 674–685 · 2023 · doi:10.1093/jee/toad044
A. P. Abbate, J. W. Campbell, G. R. Williams (Auburn University, Alabama). Abstract read. Bumble bees carried on average 46% more kiwifruit pollen than honey bees; artificially pollinated flowers set more fruit, with greater weight, size and seed number, than insect-pollinated ones; wind and pollen exclusion produced few fruit. The authors limit their advice to growers in conditions like theirs.
Do buzz-pollinating bumble bees facilitate honey bee pollination in southern highbush blueberry through increasing pollen release?
Peer-reviewed article · Ecology and Evolution 16(3): e73208 · 2026 · doi:10.1002/ece3.73208
J. J. Ternest, P. R. Muñoz, R. E. Mallinger (University of Florida). Abstract read. In cages with no alternative forage, honey bees released and collected southern highbush blueberry pollen even without buzz pollinators, and bumble bees did not raise honey bee pollen loads; the two did forage differently across temperatures and interacted more, and berry weight did not differ at the high bee densities used.

Peer-reviewed article · Agriculture, Ecosystems and Environment 359: 108757 · 2024 · doi:10.1016/j.agee.2023.108757
L. F. Ávila and others. Abstract read. Fire-blight antibiotics are sprayed on pear and apple during bloom. In the pear orchards studied, honey bees visited fewer flowers after an antibiotic spray but pollination and seed set did not differ — and the cultivars studied could self-pollinate, so the authors caution that more pollinator-dependent crops may be affected.
Drought reduces floral resources for pollinators
Peer-reviewed article · Global Change Biology 24(7):3226–3235 (Phillips, Shaw, Holland and colleagues) · 2018 · 10.1111/gcb.14130
Rain shelters simulated drought on calcareous grassland in the UK, on four experimental plant communities. Under drought, Lathyrus pratensis and Prunella vulgaris had a lower proportion of flowers containing nectar and Onobrychis viciifolia fewer flowers per raceme; floral units fell in every community and floral species richness in two. Functional diversity did not protect floral resources. Abstract read.
Climate change-induced stress reduce quantity and alter composition of nectar and pollen from a bee-pollinated species (Borago officinalis, Boraginaceae)
Peer-reviewed article · Frontiers in Plant Science 12:755843 (Descamps, Quinet and Jacquemart) · 2021 · 10.3389/fpls.2021.755843
Borage grown at +3 and +6 °C and under water stress. Nectar fell from 6.1 µl per flower in controls to 0.8 µl under combined heat and water stress, a 60% fall in nectar sugar per flower. Heat, but not water stress, halved pollen weight per flower while raising pollen polypeptide concentration by 65%. Amino-acid composition of nectar and pollen changed. One species, in growth chambers. Abstract read.
The control of water collection in honey bee colonies
Peer-reviewed article · Behavioral Ecology and Sociobiology 41:407–422 (Kühnholz and Seeley) · 1997 · 10.1007/s002650050402
The classic study of how a colony increases water collection when its nest overheats, with water used for evaporative cooling. Cited for the existence of colony-level water collection in heat, not for any threshold. Bibliographic record checked on Crossref.
Climate-associated phenological advances in bee pollinators and bee-pollinated plants
Peer-reviewed article · Proceedings of the National Academy of Sciences 108(51):20645–20649 (Bartomeus and colleagues) · 2011 · 10.1073/pnas.1115559108
Over 130 years, the phenology of ten wild bee species in north-eastern North America advanced by a mean of 10.4 ± 1.3 days, mostly since 1970. Estimated rates for bee-pollinated plants were not distinguishable from the bees', suggesting emergence is keeping pace with flowering — at least among the generalist species studied. Regional and taxon-specific. Abstract read.
Phenology of farmland floral resources reveals seasonal gaps in nectar availability for bumblebees
Peer-reviewed article · Journal of Applied Ecology 56(7):1585–1596 (Timberlake, Vaughan and Memmott) · 2019 · 10.1111/1365-2664.13403
Whole-farm nectar supply on replicate farms in south-west England: peaks in May and July, a 'June gap' between, and low supply in March and August–September, when supply is unlikely to meet bumblebee demand. Pasture and woodland gave the largest share by area; hedgerows and field margins gave the most nectar per unit area. Half of all nectar came from three species. Abstract read.
Honey bee diet in intensive farmland habitats reveals an unexpectedly high flower richness and a major role of weeds
Peer-reviewed article · Ecological Applications 25(4):881–890 (Requier and colleagues) · 2015 · 10.1890/14-1011.1
Five years of pollen and nectar collection in French intensive farmland. Collection was bimodal, with a two-month low between the oilseed rape and sunflower blooms. Nectar came mainly from crops; pollen from many herbaceous and woody species in semi-natural habitat and from weeds in crops, which made up to 40% of the diet between crop blooms. Abstract read.
Fungicide contamination reduces beneficial fungi in bee bread based on an area-wide field study in honey bee, Apis mellifera, colonies
Peer-reviewed article · Journal of Toxicology and Environmental Health, Part A 76(10):587–600 (Yoder and colleagues) · 2013 · 10.1080/15287394.2013.798846
Bee bread from colonies pollinating orchards at seven locations over two years was analysed for fungicide residues and culturable fungi; fewer fungal isolates were found as fungicide residues rose. A culture-based field association; its framing of bee bread as fungally fermented is contested by later work (Anderson 2014). Abstract read.
Seed coating with a neonicotinoid insecticide negatively affects wild bees
Peer-reviewed article · Nature 521:77–80 (Rundlöf and colleagues) · 2015 · 10.1038/nature14420
Replicated, matched landscapes in Sweden. Oilseed rape grown from seed coated with clothianidin plus the pyrethroid β-cyfluthrin reduced wild bee density, solitary bee nesting, and bumblebee colony growth and reproduction under field conditions; honey bee colonies showed no significant response. Abstract read.
A common pesticide decreases foraging success and survival in honey bees
Peer-reviewed article · Science 336:348–350 (Henry and colleagues) · 2012 · 10.1126/science.1215039
Foragers fitted with radio-frequency tags and given a non-lethal dose of thiamethoxam failed to return home more often; a model projected that this could put a colony at risk. The dose's field realism and the model's parameters were disputed (Cresswell and Thompson 2012). Abstract read.
Comment on 'A common pesticide decreases foraging success and survival in honey bees'
Peer-reviewed article · Science 337:1453 (Cresswell and Thompson), with the authors' reply · 2012 · 10.1126/science.1224618
Recalculating Henry and colleagues' colony model with parameters for the season when most treated flowering crops bloom, the projected collapse disappears. The homing result itself is not contested here; its colony consequence is. Abstract read.
Diesel exhaust rapidly degrades floral odours used by honeybees
Peer-reviewed article · Scientific Reports 3:2779 (Girling and colleagues) · 2013 · 10.1038/srep02779
A synthetic eight-compound oilseed rape floral blend exposed to diesel exhaust lost four compounds significantly within a minute, two to undetectable levels; honey bees trained to the full blend recognised the altered blend less well. The nitrogen oxides were the key agent at environmentally relevant levels. Laboratory chemistry and conditioning; no field foraging was measured. Abstract read.
Island-wide removal of honeybees reveals exploitative trophic competition with strongly declining wild bee populations
Peer-reviewed article · Current Biology 35(7):1576–1590 (Pasquali and colleagues) · 2025 · 10.1016/j.cub.2025.02.048
On the protected island of Giannutri, Italy (2.6 km², one apiary of 18 hives), hives were closed on selected days at the peak of wild bee foraging. Even 11-hour removals raised nectar volume by about 60% and pollen availability by about 30% in the most-visited plants; Anthophora dispar and Bombus terrestris became dominant in the visitation network and foraged more intensively. Transects recorded an ~80% decline in both species over four years, which the authors judge consistent with honey bees monopolising floral resources. One island system. Abstract read.
Controlling the impact of the managed honeybee on wild bees in protected areas
Peer-reviewed article · Scientific Reports 8:9308 (Henry and Rodet) · 2018 · 10.1038/s41598-018-27591-y
Rosemary scrubland in southern France, under different apiary sizes and distances. High-density beekeeping lowered wild bee occurrence (−55%) and nectar foraging success (−50%), and also the honey bees' own nectar (−44%) and pollen (−36%) harvest. Effects reached 600–1,100 m from apiaries; the authors found distance thresholds more workable than density thresholds. Abstract read.

360 sites across all major land uses in four British cities. Residential gardens and allotments were pollinator hotspots — gardens by their extent, allotments by their pollinator diversity and their leverage on city-scale network robustness. Household income was positively associated with pollinator abundance in gardens. Abstract read.
Insect fat body: energy, metabolism, and regulation
Peer-reviewed article · Annual Review of Entomology 55:207–225 (Arrese and Soulages) · 2010 · 10.1146/annurev-ento-112408-085356
Review: the fat body is a dynamic tissue with multiple metabolic functions, storing energy as glycogen and triglycerides in its adipocytes and releasing it on demand; lipid metabolism there supports growth, reproduction and non-feeding periods. General to insects, not specific to bees. Abstract read.
Varroa destructor feeds primarily on honey bee fat body tissue and not hemolymph
Peer-reviewed article · Proceedings of the National Academy of Sciences 116(5):1792–1801 (Ramsey and colleagues) · 2019 · 10.1073/pnas.1818371116
Evidence from feeding-site imaging and diet experiments that Varroa feeds primarily on fat body tissue rather than haemolymph, overturning the long-standing account. Abstract read.
The gene vitellogenin has multiple coordinating effects on social organization
Peer-reviewed article · PLOS Biology 5(3):e62 (Nelson, Ihle, Fondrk, Page and Amdam) · 2007 · 10.1371/journal.pbio.0050062
Using RNA interference, shows that vitellogenin gene activity paces the onset of foraging, primes bees for specialised (pollen or nectar) foraging, and influences worker longevity — a yolk-precursor gene co-opted into the regulation of social behaviour. Abstract read.
Immune pathways and defence mechanisms in honey bees Apis mellifera
Peer-reviewed article · Insect Molecular Biology 15(5):645–656 (Evans and colleagues) · 2006 · 10.1111/j.1365-2583.2006.00682.x
Genome-wide analysis of individual immunity: models for four immune signalling pathways with plausible orthologues for nearly all members, but roughly one-third as many genes as Drosophila and Anopheles in 17 immunity gene families. The authors suggest this reflects social barriers to disease or a limited set of co-evolved pathogens. Abstract read.
Regulation of division of labor in insect societies
Peer-reviewed article · Annual Review of Entomology 37:637–665 (Robinson) · 1992 · 10.1146/annurev.en.37.010192.003225
Review of how division of labour is regulated in insect societies, including honey bee age polyethism and its plasticity under changed colony conditions, with juvenile hormone among the regulators discussed. Bibliographic record checked; cited for that framing, not for numbers.
The gene csd is the primary signal for sexual development in the honeybee and encodes an SR-type protein

Social signal learning of the waggle dance in honey bees
Peer-reviewed article · Science 379:1015–1018 (Dong, Lin, Nieh and Tan) · 2023 · 10.1126/science.ade1702
Bees that could not follow dances before they first danced produced more disordered dances, with larger angle errors, and encoded distance incorrectly. The angle errors improved with experience; the distance error was set for life. Bees that could follow dancers showed neither impairment. Abstract read.
Do honeybees have two discrete dances to advertise food sources?
Peer-reviewed article · Animal Behaviour 75(4):1291–1300 (Gardner, Seeley and Calderone) · 2008 · 10.1016/j.anbehav.2007.09.032
Re-examined the classical split between a 'round dance' for near food and a 'waggle dance' for distant food, and concluded that the two are not discrete: dances for near sources also contain waggle runs, and the forms grade into one another. Bibliographic record checked on Crossref; cited for that conclusion only.
The vibration signal, modulatory communication and the organization of labor in honey bees, Apis mellifera
Peer-reviewed article · Apidologie 35(2):117–131 (Schneider and Lewis) · 2004 · 10.1051/apido:2004006
Review of the vibration ('shaking') signal: a worker grips another bee and vibrates her body dorso-ventrally, which raises the receiver's general activity rather than directing a particular task — a modulatory signal. Bibliographic record checked on Crossref; cited for that characterisation.
Dietary pollen and carbohydrate sources influence longevity, physiology, and gut microbiota in honey bee (Apis mellifera)
Peer-reviewed article · Scientific Reports 16:17589 (Najarpoor, Namin, Ghosh and Jung) · 2026 · 10.1038/s41598-026-48586-0
Laboratory cages: corn syrup or sucrose syrup crossed with rapeseed, kiwi or mixed pollen. Corn-syrup bees lived longer and had larger hypopharyngeal glands; mixed pollen gave higher survival, larger gland acini and higher vitellogenin. Relative abundance of Snodgrassella and Gilliamella was higher on the single pollens and of Lactobacillus on mixed pollen. The authors' conclusion about colony resilience goes beyond what a cage study measures and is not carried. Abstract read.
Evaluating effects of a critical micronutrient (24-methylenecholesterol) on honey bee physiology
Peer-reviewed article · Annals of the Entomological Society of America 113(3):176–182 (Chakrabarti, Lucas and Sagili) · 2020 · 10.1093/aesa/saz067
Caged bees on artificial diets with 0–1% 24-methylenecholesterol: survival, diet consumption, head protein and abdominal lipid were significantly higher with the sterol. Notes that phytosterols are precursors of moulting hormones and building blocks of cell membranes. Abstract read.
Specialization and adaptation in pollen sterol use by wild bees
Peer-reviewed article · iScience 29:115264 (Baker and colleagues) · 2026 · 10.1016/j.isci.2026.115264
Honey bees incorporate a subset of pollen sterols into their tissues rather than converting phytosterols to cholesterol as most herbivorous insects do. Across 56 bee species, 24-methylenecholesterol, isofucosterol and β-sitosterol were the main tissue sterols in most, but not all; generalists held more 24-methylenecholesterol than specialist relatives, and Asteraceae specialists used sterols generalists did not. Abstract read.
Bumble bees regulate their intake of essential protein and lipid pollen macronutrients
Peer-reviewed article · Journal of Experimental Biology 219:3962–3970 (Vaudo and colleagues) · 2016 · 10.1242/jeb.140772
Bombus terrestris adults restricted to single diets over-ate protein on low-fat diets and lipid on high-fat diets to reach their targets; they survived best at a 10:1 protein-to-lipid ratio, and the risk of dying rose with dietary lipid above 5:1. Workers of B. terrestris and B. impatiens offered complementary paired diets self-selected towards an intake target. Bumble bees, not honey bees. Abstract read.
Diet effects on honeybee immunocompetence
Peer-reviewed article · Biology Letters 6(4):562–565 (Alaux, Ducloz, Crauser and Le Conte) · 2010 · 10.1098/rsbl.2009.0986
Caged bees on single-plant or mixed pollens. Protein feeding changed immune measures, but more dietary protein did not raise them; diet diversity did, and mixed pollens gave higher glucose oxidase activity — the enzyme bees use to sterilise colony food — than single pollens, including protein-richer ones. Abstract read.
Nutritional control of reproductive status in honeybees via DNA methylation
Peer-reviewed article · Science 319:1827–1830 (Kucharski, Maleszka, Foret and Maleszka) · 2008 · 10.1126/science.1153069
Silencing the DNA methyltransferase Dnmt3 in newly hatched larvae had a royal-jelly-like effect: most treated larvae emerged as queens with developed ovaries. Shows that caste is a developmental switch set by diet acting on an epigenetic system, not a substance acting alone. Abstract read.
Royalactin induces queen differentiation in honeybees
Peer-reviewed article · Nature 473:478–483 (Kamakura) · 2011 · 10.1038/nature10093
Proposed that a single royal jelly protein, royalactin (monomeric MRJP1), induces queen development. Disputed by Buttstedt and colleagues (2016). Carried as a disputed claim, not as the explanation of caste.

Microorganisms in honey
Peer-reviewed article · International Journal of Food Microbiology 31:1–26 (Snowdon and Cliver) · 1996 · 10.1016/0168-1605(96)00970-1
Review: microbes in honey come from pollen, the bees' digestive tract, dust, air, soil and nectar, and from handling after harvest. Honey's properties prevent most from growing; yeasts and spore-forming bacteria are those that persist. A food-microbiology account, distinct from the bee's gut community.

Using within-day hive weight changes to measure environmental effects on honey bee colonies
Peer-reviewed article · PLoS ONE 13(5):e0197589 (Meikle, Holst, Colin, Weiss, Carroll, McFrederick and Barron) · 2018 · 10.1371/journal.pone.0197589
Within-day weight change largely reflects foragers leaving and returning and the arrival of nectar, pollen and water. Models of the daily weight curve were tested on colonies subjected to malnutrition, and a third study delayed forager departure by one to three hours with screen gates to test what the size and timing of the morning weight drop mean. Depending on the effect's size relative to the scale's precision, within-day change can show colony-level effects that periodic inspections miss. Abstract read.
Remote detection of the swarming of honey bee colonies by single-point temperature monitoring
Peer-reviewed article · Biosystems Engineering 148:76–80 (Zacepins, Kviesis, Stalidzans, Liepniece and Meitalovs) · 2016
Ten colonies in Latvia, May to August 2015; nine swarms observed. One temperature sensor above the nest, read once a minute, showed a warm-up of about 1.5–3.4 °C in the 8–20 minutes before take-off, and a decision rule detected swarming at that stage. Detection at take-off, not forecasting days ahead. Abstract and highlights read.
Do honeybees, Apis mellifera scutellata, regulate humidity in their nest?
Peer-reviewed article · Naturwissenschaften 93(8):397–401 (Human, Nicolson and Dietemann) · 2006
Measured humidity in the brood nest of African honey bee colonies; later work from the same group cites it for brood-nest relative humidity of roughly 50–60%, a humidity gradient from the centre outwards, and both active and passive contributions. One subspecies in South Africa; not a threshold for other bees or climates. Bibliographic record and citing summaries read.
Atmospheric carbon dioxide regulation in honey-bee (Apis mellifera) colonies
Peer-reviewed article · Journal of Insect Physiology 20:2301–2305 (Seeley) · 1974
Varying carbon dioxide, oxygen and nitrogen around colonies showed that carbon dioxide, and not the other gases, changed fanning: workers ventilate when CO2 rises, which limits its build-up. The expected link between CO2 build-up and swarming was not supported. Bibliographic record and citing summaries read.
Detection of honeybee disease: varrosis using a semiconductor gas sensor array
Peer-reviewed article · Proceedings of SENSORNETS 2019, SciTePress (Szczurek and colleagues) · 2019 · 10.5220/0007575600580066
Six commercial semiconductor gas sensors sampled hive air in field conditions in Poland — hives of different materials and locations, various weather and times of day. The best classification of infested against non-infested colonies had a misclassification error of 17% (k-nearest neighbours). A conference paper from one research group; the follow-up work grades infestation into low, medium and high. Abstract read.
The prediction of swarming in honeybee colonies using vibrational spectra
Peer-reviewed article · Scientific Reports 10:9798 (Ramsey, Bencsik and colleagues) · 2020 · 10.1038/s41598-020-66115-5
Accelerometers embedded in the wax of central brood frames in 25 hives in France and England, 2014–2015. Two methods: instantaneous night-time spectra (classification error 6.3%; 3 of 18 swarming datasets missed, 0 of 14 non-swarming false alarms, averaged warning 22 days) and ten-day spectral change (error 1.92%; 5 of 18 missed, 2 of 14 false alarms, warning about 10 days). Swarm events were identified from the vibration spectrograms; no held-out test set is described, and frames from one hive were treated as separate datasets. The instantaneous method worked only within the swarming season, daytime foraging caused hourly false alarms, and autumn swarming was not tested. Full text read.

RFID tracking of sublethal effects of two neonicotinoid insecticides on the foraging behavior of Apis mellifera
Peer-reviewed article · PLoS ONE 7(1):e30023 (Schneider, Tautz, Grünewald and Fuchs) · 2012 · 10.1371/journal.pone.0030023
Individual foragers carried RFID tags, with readers at the hive entrance and at an artificial feeder. After a single oral dose, foraging fell and flights lengthened at ≥0.5 ng per bee of clothianidin and ≥1.5 ng of imidacloprid during the first three hours; no adverse effect was seen at doses the authors call field-relevant. The authors conclude RFID records short-term changes in foraging well. Abstract read.
Searching for nests of the invasive Asian hornet (Vespa velutina) using radio-telemetry
Peer-reviewed article · Communications Biology 1 (Kennedy, Ford, Poidatz, Thiéry and Osborne) · 2018 · 10.1038/s42003-018-0092-9
Hornet workers caught at hives, flowers and bait stations in southern France and Jersey were fitted with VHF radio tags and followed: five previously unknown nests were found, up to 1.33 km from release. Tags of 0.28 g were carried when the tag-to-hornet weight ratio stayed below 0.8. Full text summary read.
Long-wave infrared imaging for non-invasive beehive population assessment
Peer-reviewed article · Optics Express 19(1):399 (Shaw, Nugent, Johnson, Bromenshenk, Henderson and Debnam) · 2011
A radiometrically calibrated uncooled thermal camera, 3–4 m from the hives, recorded the radiance of the hive's outer surfaces. The images do not show the interior; spatial variation in surface radiance was related to approximate population. Read through the bibliographic record and the 2011 trade-press report of the paper; cited for the method and its outer-surface limit.
Vit4V: a video classification method for the detection of Varroa destructor from honeybees
Peer-reviewed article · Proceedings of the IEEE/CVF CVPR Workshops 2025, pp. 5343–5351 (Giovannesi, Russo and Beraldi) · 2025
Classifies short video clips of forager bees as carrying a visible mite or not, instead of single images, to cope with motion blur and occlusion. A public dataset of 607 videos of infected and healthy bees was recorded at an active hive with an embedded camera, designed with entomologists. Aggregating predictions across clips gave an accuracy of 0.986. The abstract does not state the number of colonies, the place, the split between training and test videos, or metrics other than accuracy. Abstract read.

Beehive-entrance imaging and deep learning for real-time monitoring of Varroa destructor in apiculture
Peer-reviewed article · Journal of Invertebrate Pathology 214:108465 (Su, Wu, Lin and Liu) · 2026 · 10.1016/j.jip.2025.108465
Conventional hives retrofitted with an entrance imaging chamber, in Taiwan; a YOLOv5s detector trained on 1,600 annotated images supplemented with mite close-ups reached a mean average precision of 97.4% at an overlap threshold of 0.5 (mAP@0.5) — a measure of finding and outlining mites in images, not of colony infestation. Video tests at hive entrances showed robust detection despite motion and lighting variation. The paper adds a per-hive bill of materials and a five-year cost model. The abstract does not give the number of hives in the video tests or a comparison with a wash count. Abstract read.
A computer vision system to monitor the infestation level of Varroa destructor in a honeybee colony
Peer-reviewed article · Computers and Electronics in Agriculture 164:104898 (Bjerge and colleagues) · 2019 · 10.1016/j.compag.2019.104898
Bees from a chosen frame were shaken in front of a portable unit with multispectral lighting and filmed for 5–20 minutes in Denmark; a deep-learning estimator counted bees and located mites. On a test video of 1,775 bees and 98 mites the estimated infestation was 5.80% against 5.52% counted by hand. Bee detection F1 0.97, mite detection F1 0.91. The estimate describes the imaged bees, and needs a frame to be shaken out. Abstract and summaries read.
Automatic detection and classification of honey bee comb cells using deep learning
Peer-reviewed article · Computers and Electronics in Agriculture 170:105244 (Alves and colleagues) · 2020 · 10.1016/j.compag.2020.105244
Photographs of frames with the bees removed. Cells were found with a circle Hough transform and semantic segmentation (detection rate 98.7%), then sorted into seven content classes by thirteen convolutional networks; MobileNet was the best compromise, with an F1 score of 94.3% and about 9 seconds per comb image. Models, code and data released. Classifying what a cell contains is not diagnosing a brood disease. Abstract read.
Autonomous tracking of honey bee behaviors over long-term periods with cooperating robots
Peer-reviewed article · Science Robotics 9(95) (Ulrich, Krajník, Schmickl and colleagues) · 2024 · 10.1126/scirobotics.adn6848
Cooperating camera robots in an observation hive at the University of Graz followed the queen across two combs for long periods and, while she rested, imaged workers, brood, pollen and honey; about 1.4 TB of images a day. Experimental robotics in a research facility, not a field beehive. Read through the publisher record and the institutions' reports.
Honey as a source of environmental DNA for the detection and monitoring of honey bee pathogens and parasites
Peer-reviewed article · Veterinary Sciences 7(3):113 (Ribani, Utzeri, Taurisano and Fontanesi) · 2020 · 10.3390/vetsci7030113
DNA from 102 honey samples (74 from Italy, 28 from 17 other countries) was tested for nine honey bee pathogens and parasites. The authors conclude honey DNA could underpin tools for monitoring the health status of honey bee populations. A DNA signal in honey records presence somewhere in the colony's history, not an active infection in a particular colony. Abstract read.
Shotgun sequencing of honey DNA can describe honey bee derived environmental signatures and the honey bee hologenome complexity
Peer-reviewed article · Scientific Reports 10 (Bovo, Utzeri, Ribani, Cabbri and Fontanesi) · 2020 · 10.1038/s41598-020-66127-1
Deep sequencing of three polyfloral honeys from 2018 found DNA from 191 organisms across viruses, bacteria, plants, fungi, protozoa, arthropods and mammals, including hive and gut microbes and honey bee pathogens, parasites and pests. Three samples; a description of what honey DNA can contain, not a surveillance validation. Abstract read.
An intelligent monitoring system for forecasting and anomaly detection in precision beekeeping
Peer-reviewed article · Scientific Reports 16:7080 (Huet, Bougueroua and Metidji) · 2026 · 10.1038/s41598-026-37877-1
Two hives in Germany from the open HOBOS dataset (2016–2019): internal temperature, humidity and weight. Recurrent networks and Prophet were compared as forecasters; test mean absolute error 0.61 °C for temperature, 3.8 percentage points for humidity and 0.94 kg for weight, with one hive held out. Four anomaly detectors were compared, but there were no labelled anomalies, so the authors report only the share of points flagged, which is not accuracy. The dashboard prototype ran on simulated data, and the authors call for cross-site validation. Full text read.
Mapping the phenology of European honey bee nectar flows
Monograph · MSc thesis, University of Edinburgh (Blomstedt)
Compared smoothed satellite vegetation index (MODIS NDVI) seasons with hive-scale weight gain at sites in Slovenia, Switzerland, Belgium and Finland, 2009–2012. The NDVI start of season did not correlate with the start of the nectar flow; it was related to the flow's midpoint (R² = 0.73). An unpublished thesis read as its abstract; cited only for the gap between a greenness proxy and what bees collect.
Assessing the value of pollination: comparing “old” and “new” dependence ratios in Spanish agriculture sector
Peer-reviewed article · Journal for Nature Conservation 92:127284 (Kasanzew, Thomasz and García-García) · 2026 · 10.1016/j.jnc.2026.127284
Full text read (open access, CC BY, from the University of Extremadura repository). Applies two sets of dependence ratios — Gallai and Vaissière (2009) and Siopa et al. (2024) — to official production, area and price data for 35 crops in Spain's 17 Autonomous Communities, 2010–2021, at constant average 2010–2021 prices. The share of agricultural gross production value attributed to pollination rises from 8% to 10% (minimum), 12% to 18% (mean) and 16% to 25% (maximum); the abstract gives an average of €2.8–4 billion a year. The paper's discussion section states the mean as 12% to 16%, which conflicts with its abstract and results (18%); the results figure is used here. Changes are driven mainly by citrus and tomato (higher new ratios) and stone fruit (lower). The authors exclude seed production, note that the ratios do not separate wild from managed pollinators, and that no Spain-specific dependence coefficients exist.
Animal-pollinated crops and cultivars — a quantitative assessment of pollinator dependence values and evaluation of methodological approaches
Peer-reviewed article · Journal of Applied Ecology 61(6):1279–1288 (Siopa, Carvalheiro, Castro, Loureiro and Castro) · 2024 · 10.1111/1365-2664.14634
Abstract read. Continuous pollinator-dependence values for 141 crops and 317 cultivars or accessions, 37 of the crops not in earlier compilations, from pollination experiments worldwide. Pollen limitation appeared in 51% of entries, so dependence estimated from open pollination alone underestimates it. Cited as the newer dependence set; not as a monetary value.
Assessing the economic impact of insect pollination on the agricultural sector: a department-level case study in France
Peer-reviewed article · Environmental and Sustainability Indicators 28:100944 (Blili, Abou Nader and colleagues) · 2025 · 10.1016/j.indic.2025.100944
Bibliographic summary of the abstract read; full text not retrieved. 2022 data for 34 major crops, 26 of them pollinator-dependent, mapped by French department: crop production value about €34.8 billion, insect pollination value about €4.2 billion, a vulnerability rate of about 12%. Per-hectare value highest in Loire-Atlantique and lowest in Seine-Saint-Denis. Limitations named: approximated crop prices, fixed dependence ratios that ignore local ecology, minor crops excluded. Which dependence set was used was not confirmed from what was read.
The economic, agricultural, and food security repercussions of a wild pollinator collapse in Europe
Peer-reviewed article · Nature Communications 16:9892 (Feuerbacher, Kempen, Steidle and Wieck) · 2025 · 10.1038/s41467-025-65414-7
Full text read in PubMed Central. A modelled scenario, not an observation: the CAPRI partial-equilibrium model, with a collapse of at least 90% of wild pollinators confined to Europe by 2030 and managed pollinators held unchanged. Projected for 2030 against a no-collapse baseline: European crop yields 7.8% lower, producer prices of pollination-dependent products 18.6% higher, a global welfare loss of €34.4 billion (range €23.2–44.0 billion), €23.8 billion of it in Europe, and a gain of €4.6 billion to producers globally. The authors call the collapse an extreme what-if; substitutes such as hand pollination, crop quality and seed production are not modelled, and the price basis year of the euro figures is not stated.
The economic value of pollination services for seed production: a blind spot deserving attention
Peer-reviewed article · Environmental and Resource Economics 87(4):881–905 (Feuerbacher, Herbold and Krumbe) · 2024 · 10.1007/s10640-024-00840-7
Abstract read. Many crops whose marketed output needs no pollinator depend on pollination to produce their seed. A partial-equilibrium framework applied to Germany finds the value of pollination services about 33% higher when seed production is counted, from higher seed costs and from the extra seed needed for the land expansion that would offset a pollinator collapse.
Pollination services valued at $400 million on 1.7 million acres
Government statistics · United States Department of Agriculture, Economic Research Service (Charts of Note) · 2025
Published 18 June 2025, from NASS Cost of Pollination estimates for 2024. Producers spent more than $400 million on pollination services on 1.728 million paid acres (down more than 7% from 1.862 million in 2023); almonds $325.8 million, about 81%, at about $181 a colony against an average of $66 for all other crops. Beekeepers reported $361.5 million of honey production revenue in 2024. ERS states that beekeepers have reported earning more from pollination services than from honey since 2022 — a comparison of the growers' fee survey with the honey value of production, two different surveys. Its $361.5 million for 2024 honey predates the March 2026 NASS release, which reports 2024 honey at $323.9 million.
