Biotic and abiotic stresses on honeybee health
This review covers the many threats facing honeybee health, including parasites, pesticides, habitat loss, climate change, and emerging pollutants like microplastics. Microplastics have been found in bee habitats and can be ingested during foraging, potentially affecting bee health and colony survival. Since honeybees are essential crop pollinators, threats to their health from microplastic pollution could indirectly impact human food production.
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.
Pollination under attack: First insights from Türkiye Plain reveal microplastics in bees from both urban and rural areas
Researchers found microplastics inside honeybees from both urban and rural areas in Turkey, with urban bees carrying significantly higher concentrations — mostly PET plastic fibers — raising concern that microplastic contamination could threaten pollinator health and the agricultural pollination services bees provide.
Tetracycline 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.
Management practice for small hive beetle as a source of microplastic contamination in honey and honeybee colonies
Researchers discovered that microfiber wipes used inside beehives to trap small hive beetles are actually a significant source of microplastic contamination in honey and honeybee colonies. When bees chew on these non-woven wipes, the material breaks apart into tiny fibers that contaminate the hive environment. The study suggests that a common beekeeping management practice is inadvertently introducing microplastics into honey, raising concerns for both bee health and food safety.
Use of Gas Chromatography and SPME Extraction for the Differentiation between Healthy and Paenibacillus larvae Infected Colonies of Bee Brood—Preliminary Research
Researchers used gas chromatography with SPME extraction to analyze volatile organic compounds in honey bee brood from healthy hives and those infected with Paenibacillus larvae, identifying distinct VOC profiles that could potentially serve as early diagnostic markers for American foulbrood disease.
Underexplored food safety hazards of beekeeping products: Key knowledge gaps and suggestions for future research
This review examines underexplored food safety risks in bee products like honey, royal jelly, and propolis, including contamination from microplastics and other environmental pollutants. Bees can pick up microplastics from the environment during foraging, transferring them into hive products that humans consume. The authors highlight that while pesticides and heavy metals in honey are well studied, microplastic contamination in beekeeping products needs more attention.
Microplastics reach the brain and interfere with honey bee cognition
Researchers found that microplastics reach honey bee brains and impair cognitive function, with bees exposed to mixed polymer combinations showing disrupted learning and memory abilities, demonstrating that plastic pollution poses a direct threat to pollinator health.
Developing Strategies to Help Bee Colony Resilience in Changing Environments
This review identified strategies for improving bee colony resilience under multiple stressors including climate change, pathogen pressure, and pesticide exposure, with a focus on the links between nutrition, gut microbiota, and immune and stress response systems. The authors highlight dietary diversity and microbiome support as practical levers for maintaining colony health.
Evaluation of microplastic pollution using bee colonies: An exploration of various sampling methodologies
This study evaluated honeybees, pollen, and a novel in-hive passive sampler called the APITrap as biological and passive monitors for microplastic pollution, finding that honeybees and pollen effectively captured particles from the surrounding environment.
Aspergillus-bees: A dynamic symbiotic association
This review examined the dynamic relationship between Aspergillus fungi and bees, documenting over 30 Aspergillus species isolated from managed and wild bees and exploring how environmental stressors may shift this association from commensal to pathogenic.
Effect of Nosema apis and N. ceranae on honey bee Apis mellifera queen development
Researchers experimentally infected royal jelly in queen cells with Nosema apis and N. ceranae spores at high and low concentrations and mixed combinations to assess effects on honey bee queen development across seven treatment groups. The study examined how nosemosis-causing microsporidian parasites impact queen developmental outcomes, addressing a knowledge gap in understanding disease effects on reproductive castes.
Unravelling the microplastic menace: Different polymers additively increase bee vulnerability
Researchers exposed bees to two common types of microplastics, both individually and combined, and found that the mixture caused additive harmful effects on survival and behavior. The microplastics impaired the bees' ability to learn and remember, which is critical for finding food and navigating. Since bees are essential pollinators for food crops, microplastic pollution threatening bee health could have indirect consequences for human food production.
Microplastic contamination in the agri-food chain: The case of honeybees and beehive products
Researchers investigated microplastic and microfiber contamination in honeybees and beehive products across urban and rural areas in Southern Italy. They confirmed that microplastics were present on bee bodies and in honey, wax, and propolis regardless of the surrounding environment, indicating widespread airborne contamination. The findings suggest that honeybees and their products could serve as bioindicators for monitoring microplastic pollution in the atmosphere.
Insights into the Role of Natural Products in the Control of the Honey Bee Gut Parasite (Nosema spp.)
This review examined the potential of natural products including plant extracts, essential oils, and organic acids as alternatives to pharmaceutical treatments against the honey bee gut parasite Nosema spp. Several natural compounds showed anti-Nosema activity in laboratory studies, but field efficacy and safe application protocols remain incompletely characterized.
Single and Synergistic Effects of Microplastics and Difenoconazole on Oxidative Stress, Transcriptome, and Microbiome Traits in Honey Bees
Researchers exposed honey bees to microplastics and the fungicide difenoconazole, both alone and together, and found that the combination caused worse oxidative stress and gut microbiome disruption than either pollutant alone. This is concerning because bees encounter both pollutants in agricultural environments, and the combined exposure may weaken their health more than expected.
Environmental Sources of Possible Associated Pathogens and Contaminants of Stingless Bees in the Neotropics
This review examines the environmental pathogens and contaminants—including microplastics, pesticides, and parasites—that threaten stingless bee health in the Neotropics. The authors find that stingless bees are understudied compared to honeybees despite their critical ecological and economic role, and that microplastic exposure represents an emerging threat not yet well characterized.
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.
Effects of microplastic, heat and ozone on Bombus terrestris mortality and relative fat body content
This study tested how microplastic exposure, heat stress, and ozone affect bumblebee survival and fat reserves. The results showed that combining multiple stressors, including microplastics, had worse effects on bees than any single stressor alone. Bumblebee health matters to humans because these pollinators are essential for producing many fruits and vegetables in our food supply.
