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.
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.
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.
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.
Influence of Age of Infection on the Gut Microbiota in Worker Honey Bees (Apis mellifera iberiensis) Experimentally Infected with Nosema ceranae
Researchers studied how infection with the gut parasite Nosema ceranae affects the microbiome of honey bees at different ages. The study found that infected bees, especially those infected shortly after emerging, showed significant shifts in their gut bacteria populations, suggesting that both age and infection timing play important roles in how bee gut health is disrupted.
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.
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.
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.
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.
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.
Bees and Microplastic Studies: A Systematic Review
This systematic review of 33 studies found that microplastic research involving bees is still in its early stages, with evidence suggesting microplastics can alter bee gut microbiota and impair immune function. Given that compromised bee health threatens pollination services and broader ecosystem stability, the review calls for more primary studies on this understudied topic.
Biodiversity and Challenges of Honey Bee Population in Pakistan
This review examines the biodiversity and ecological challenges facing honey bee populations in Pakistan, covering threats from habitat loss, pesticide use, disease, and climate change. The authors assess the status of native bee species and managed colonies and discuss implications for agricultural pollination services and food security in the region.
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.
Emerging threats and opportunities to managed bee species in European agricultural systems: a horizon scan
Researchers and European experts identified 21 emerging threats and opportunities for managed bees used in agriculture, spanning pesticide exposure, climate stress, new parasites, and trade policies, highlighting that protecting pollination services requires coordinated action across local, national, and continental scales.
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.

This methodological review compares nanoparticle interactions with innate immune systems across species from plants to humans, identifying conserved immune pathways that can serve as cross-species models for evaluating nanoparticle and nanoplastic toxicity.
The Role of Beekeeping in the Generation of Goods and Services: The Interrelation between Environmental, Socioeconomic, and Sociocultural Utilities
This review examines the diverse ecosystem goods and services generated by beekeeping, including pollination, honey production, and cultural benefits, while documenting growing threats to bee populations from pesticides, habitat loss, and emerging pathogens. The authors argue that beekeeping supports biodiversity and food security in ways that are systematically undervalued in economic and environmental assessments.
Anatomically-specific coupling between innate immune gene repertoire and microbiome structure during coral evolution
This study found that different coral species have distinct coupling between their immune gene repertoires and microbiome composition, suggesting evolutionary specialization of host-microbe relationships. Coral microbiomes are being disrupted by plastic pollution, making understanding baseline coral immunity relevant to assessing plastic pollution impacts on reef health.
Gut microbiota protects honey bees (Apis mellifera L.) against polystyrene microplastics exposure risks
Researchers found that honey bees with intact gut microbiota were significantly more resilient to polystyrene microplastic exposure than bees with disrupted gut communities. The gut microbiota helped reduce oxidative stress and maintained immune function in bees exposed to microplastics. The study suggests that a healthy gut microbiome may serve as a natural defense mechanism against the harmful effects of microplastic ingestion in pollinators.
Nano- and micro-polystyrene plastics disturb gut microbiota and intestinal immune system in honeybee.
Honeybees orally exposed to polystyrene micro- and nanoplastics showed disrupted gut microbiota and impaired intestinal immune function, with nanoplastics causing greater effects than microplastics. Since honeybees are critical pollinators for food production, microplastic contamination in their environment could affect both bee health and agricultural systems.
