Summary: The loss of honey bee colonies is attributed to factors such as habitat degradation, parasites, pathogens, and exposure to pesticides. Bee products like honey, wax, and pollen can be contaminated by pesticides, potentially affecting colony health. Understanding pesticide residues in larval food jelly and factors influencing contaminant concentration is important for risk assessment and protecting honey bee brood.

Summary: This study investigates the effects of antibiotic treatment on the bio-efficiency and histological structure of honeybee larvae. The results demonstrate that high concentrations of Tetracycline can lead to larval mortality and significant histological changes in the midgut cells. Antibiotic exposure can have negative impacts on the health of honeybees.

Summary: This study characterizes the bacterium Bombella apis associated with honey bee larvae and its impact on their nutritional resilience. The research shows that B. apis is the only bacterium capable of withstanding antimicrobial larval diet and can synthesize all essential amino acids. Analysis of genes reveals the recent acquisition of multiple amino acid transporters in B. apis ancestors. Moreover, honey bee larvae supplemented with B. apis experience less mass reduction under limited nutrition.

Summary: This study aimed to investigate the presence of honey bee viruses in Oriental hornet larvae and honey bees from the same apiary. The results showed that several honey bee viruses were detected in Oriental hornet larvae, including Deformed Wing Virus, Sac Brood Virus, Black Queen Cell Virus, and Acute Bee Paralysis Virus. The same viruses were also found in honey bee samples. The transmission route of infection may be through the ingestion of infected bees by Oriental hornet larvae. However, further research is needed to confirm this hypothesis and rule out other sources of infection.

Summary: Agricultural intensification and pesticide use have negative effects on the homing ability of pollinators, with the new pesticide sulfoxaflor having higher toxicity. Homing ability tests can be used to assess the impact of these pesticides on bee health and provide valuable data for predicting colony health effects.

Summary: A meta-analysis revealed that the combined effects of pesticides and parasites on honey bee health are antagonistic rather than synergistic. Previous bias in research against stressor antagonism contributed to uncertainty about these combined effects.

Summary: Honey bees play a vital role in pollination and ecological services, significantly impacting crop productivity and the economy. However, they are susceptible to infections by various pathogens such as viruses, bacteria, fungi, and parasitic mites, which pose a threat to their health and well-being.

Summary: A two-year study in Maine wild blueberry fields monitored the health of migratory honey bee colonies in 2014 and 2015. Varroa mite infestations and pesticide residues on pollen were significant predictors of colony health, explaining 71% of the variance in colony health over the two years. Pathogen prevalence and incidence varied between the two years, with high levels of recently discovered pathogens and parasites detected.

Summary: The study reports the total synthesis and structural revision of paenilamicin B2, highlighting the N-terminal fragment as an important pharmacophore, and conducts biological activity evaluation and competition experiments with bacterial competitors in the ecological niche. It also presents data classifying paenilamicins as potential ribosome inhibitors, contributing to a better understanding of the pathogenicity of P. larvae and paving the way for future structure-activity relationship and mode-of-action studies.

Summary: Honey bees are commonly used for pesticide risk assessments, but this approach may underestimate risk to non-target species. A study found that a solitary ground-nesting bee, L. paahaumaa, was more sensitive to imidacloprid compared to honey bees, highlighting the need for more comparative toxicity studies.

Summary: A 4-year monitoring survey in China's main honey producing areas revealed that a high percentage of pollen, nectar, beebread, and honey contained detectable levels of pesticides, with pyrethroids being the most influential contributor to potential hazards for honeybee colonies. The study provides insights into the extent of contamination caused by agricultural pesticide use on honeybee colonies.

Summary: Managed honey bees have experienced high rates of colony loss due to pesticide exposure. Low doses of pesticides can weaken colonies, including impairing learning performance. The effects of fungicides on honey bee learning and the difference between pesticide formulations and active ingredients are understudied. This study found that acute exposure to the fungicide formulation Pristine had negative effects on honey bee memory, but these effects were not seen when bees were only exposed to the active ingredients. This suggests that other ingredients in the formulation mediated the learning effects. Pesticide co-formulants should be considered when assessing pesticide risks.

Summary: This study investigated the impact of rice cropping system on honey bee health and found that high pesticide exposure and forage shortage in monoculture rice systems can stress honey bees. Increasing forest habitat cover did not enhance forage availability or reduce pesticide exposure, and all colonies eventually failed. Therefore, alternative natural habitats should be considered to support bee health.

Summary: The study evaluated the risk to honey bee health posed by residues of pesticides and veterinary drugs in beeswax in Europe. Provisional action limits were proposed, and beeswax exceeding these limits should not be put on the market.

Summary: Honey bees are vital pollinators of agricultural crops, but face threats from insect growth disruptors, which target pathways crucial for insect development, reproduction, and behavior. Understanding the risks posed by these pesticides to honey bees is essential for evaluating their long-term health and productivity. This review examines the effects of insect growth disruptors on honey bees at both the individual and colony levels, and discusses potential strategies for mitigating their impacts on colony longevity.

Summary: This study examines the effects of commonly used insect growth disrupting pesticides (IGDs) on honey bee reproduction by exposing queens to these pesticides via their worker bees. The results show that different pesticides have varying effects on queen performance, worker responses, and offspring development, which may have implications for honey bee reproduction and colony health.
