ClearTetracycline exposure alters key gut microbiota in Africanized honey bees ( Apis mellifera scutellata x spp.)
Researchers found that exposure to tetracycline antibiotics significantly altered gut bacteria communities in Africanized honey bees, disrupting their microbiome health. Since bees can be exposed to antibiotics through agricultural practices, the findings raise concern about antibiotic impacts on pollinator health.
Combined transcriptome and metabolite profiling analyses provide insights into the chronic toxicity of carbaryl and acetamiprid to Apis mellifera larvae
Researchers exposed honeybee larvae to low, non-lethal doses of two common insecticides — carbaryl and acetamiprid — and found distinct disruptions in gene activity and metabolism, including effects on antioxidant defenses and amino acid processing. These findings reveal that even "safe" pesticide levels can cause subtle but meaningful biological harm to developing bees, which are essential for pollinating crops.
Influence of nano-polystyrene on cyfluthrin toxicity in honeybee Apis cerana cerana Fabricius
Researchers found that nano-polystyrene plastics damaged the gut and gland development of Asian honeybees, while also changing how the bees process toxins at the genetic level. When combined with the pesticide cyfluthrin, the nanoplastics altered detoxification and immune gene activity in complex ways. Since honeybees are essential pollinators for food crops, the toxic effects of nanoplastics on bee health could have indirect consequences for human food security.
Gut microbiota analysis of the western honeybee ( Apis mellifera L.) infested with the mite Varroa destructor reveals altered bacterial and archaeal community
Researchers used 16S rRNA amplicon sequencing to characterize bacterial and archaeal gut communities in adult honeybees (Apis mellifera) and larvae from Varroa destructor-infested hives, comparing healthy and mite-affected groups. They found Bombella dominated larval microbiota while Gillamella, Lactobacillaceae, and Snodgrassella dominated adults, though healthy and Varroa-affected adult groups did not differ statistically, and larvae showed enrichment of genes involved in cofactor and vitamin biosynthesis.
Glyphosate and Glufosinate Residues in Honey and Other Hive Products
This review examined the presence of glyphosate, glufosinate, and their metabolites in honey and other hive products, highlighting contamination pathways from agricultural herbicide use and potential risks to bee and human health.
How Environmental and Ecological Stressors Reprogram Honey Bee Chemistry Through the Microbiome–Metabolome Axis
Researchers reviewed how major environmental stressors — including pesticides, pathogens, nutritional imbalance, and contaminants — disrupt the honey bee gut microbiome-metabolome axis, finding recurring patterns of functional dysbiosis such as impaired energy metabolism and weakened immune regulation that can scale up to threaten colony resilience.
Microplastics incorporated by honeybees from food are transferred to honey, wax and larvae
Researchers found that when honeybees consume food contaminated with microplastics, the particles are transferred to honey, beeswax, and developing larvae inside the hive. Chronic exposure did not significantly affect colony growth, but the presence of microplastics in honey means humans may be ingesting them through this food source. This study reveals another pathway by which microplastics can enter the human diet through contaminated bee products.
Microbiota and Its Importance in Honey Bees
This review examines the role of microbiota in honey bee health, finding that gut microbiome composition is critical for metabolism, immune function, and protection against pathogens, with environmental stressors including pollution threatening bee microbiome stability.
Microplastics comprehensive review: Impact on honey bee, occurrence in honey and health risk evaluation
This systematic review examines how microplastics contaminate honey through bees and their environment. The findings show that bees accumulate microplastics from polluted air, water, and soil, which can then end up in honey — a product many people consume for its health benefits.
A systematic review of honey bee (Apis mellifera, Linnaeus, 1758) infections and available treatment options
This systematic review catalogued the major pathogens threatening honey bee colonies worldwide, including Varroa mites, Nosema fungi, and several viruses, along with current treatment options. The authors call for a global monitoring system to track parasite prevalence and protect pollinator health.
Combined transcriptome and metabolite profiling analyses provide insights into the chronic toxicity of carbaryl and acetamiprid to Apis mellifera larvae
Researchers exposed honeybee larvae in vitro to no-observed-adverse-effect concentrations of the insecticides carbaryl and acetamiprid and used combined transcriptome and metabolite profiling to reveal that carbaryl disrupted oxidative stress responses and amino acid metabolism, while acetamiprid altered different metabolic pathways.
Influence of Geographic Separation Between Urban Centers and Microplastic Burden on Bees (Apis mellifera)
Researchers studied whether the distance between honeybee colonies and urban centers affects the amount of microplastic contamination found on the bees. They found that bees closer to cities carried significantly more microplastics on their bodies than those in more rural areas. The study suggests that honeybees could serve as biological indicators for monitoring local microplastic pollution levels.
Preliminary data on glyphosate, glufosinate, and metabolite contamination in Italian honey samples
Researchers tested 30 honey samples from Italian retailers for glyphosate and glufosinate herbicide residues. They found measurable glyphosate in eight samples, with one wildflower honey containing nearly three times the legal maximum residue limit. The study raises concerns about pesticide contamination reaching consumers through bee products and highlights the need for continued monitoring.
Effects of different microplastic types and co-exposure on the survival of Apis mellifera ligustica (Spinola, 1806) and its associated microbial communities
Researchers fed honey bees three types of microplastics (polystyrene, polyethylene, and polymethyl methacrylate) individually and in combination, and found that all treatments significantly reduced bee survival compared to controls. The combination of all three microplastic types had the strongest negative effect, and the gut microbial community showed time- and treatment-specific shifts that may represent an initial compensatory response to maintain functional stability.
Are Honey Bees at Risk from Microplastics?
This review examines whether microplastics pose a risk to honey bee populations, noting that microplastics have been detected in honey samples and on bees collected from both urban and rural areas. Researchers found that exposure to certain polymer types may affect bee health, and the study calls for more research to understand the risks of microplastic exposure to pollinators and the broader implications for ecosystem health.
Pesticides, Herbicides and Their Effects on Pollinators
This review examined how pesticide exposure—particularly neonicotinoids—harms pollinators through direct contact, ingestion, and bioaccumulation, finding that chronic low-level exposure impairs foraging, navigation, immune function, and reproduction in bees and other pollinators.
Assessing the effects of a commercial fungicide and an herbicide, alone and in combination, on Apis mellifera: Insights from biomarkers and cognitive analysis
Researchers tested the combined effects of a commercial fungicide and herbicide on honey bees and found that the mixture was more harmful than either chemical alone. The pesticide combination impaired the bees' cognitive abilities, disrupted detoxification enzymes, and increased oxidative stress markers. The study suggests that current risk assessments, which typically evaluate pesticides individually, may underestimate the real-world dangers bees face from chemical mixtures.
The effects of anthropogenic toxins on honey bee learning: Research trends and significance
Researchers reviewed dozens of studies on how human-made toxins — especially pesticides and other agrochemicals — impair the ability of honey bees to learn, a skill critical for foraging and navigation. They found that neurotoxic insecticides are the most studied class but that testing methods vary widely, making it difficult to compare results or set reliable safety standards.
