Summary: The European Union instigated a moratorium on neonicotinoid seed treatments in 2013, but allowed their use on non-flowering crops like winter wheat. While clothianidin detection rates remained constant over three years, thiamethoxam residues disappeared and imidacloprid detection was infrequent but persistent. The highest neonicotinoid residues were associated with honey produced by foraging on oilseed rape and wild plants, leading to a full EU ban in 2018.

Summary: In this study, the microbiome of honeybees from different time points in various apiaries across Ireland was analyzed. It was found that the microbiome composition showed stronger clustering by time point rather than by apiary site. The study also revealed certain bacteria in the honeybee microbiome that were correlated with hive health, highlighting the importance of the global honeybee microbiome in supporting thriving hives.

Summary: The study revealed the impact of neonicotinoid insecticides on the expression profile of lncRNAs in young adult honey bees, indicating negative effects on carbohydrate and protein metabolism, as well as immune-inflammatory responses. The differentially expressed lncRNAs provide a basis for further exploration of lncRNA function in honey bee growth and immune response.

Summary: Queens and sterile workers in honeybees arise from genetically identical eggs but show differences in lifespan, DNA methylation, and functions. Rebels, workers with increased reproductive potential, show longer lifespan, lower global DNA methylation, and better infection tolerance compared to normal workers, expanding the potential of honeybees as a model for various biological studies. The presence of long-living rebel-workers with high reproductive potential makes honeybees particularly useful for research on senescence, nosemosis, eusocial evolution, and epigenetics.

Summary: The study reveals that neonicotinoid insecticides have a long-term impact on the gut microbial community of honeybees, leading to dysbiosis and affecting various microbial genera and species. Microbial diversity is significantly reduced, potentially compromising the ecosystemic functionality of honeybees.

Summary: During reproductive swarming, honeybee clusters can modulate their morphology in response to temperature changes, maintaining internal temperature and preserving energy. The shape and size changes of the clusters exhibit faster response to cooling than heating, and fluctuate even at a constant temperature.

Summary: This study investigated the expression profile of water-soluble proteases during the ontogenesis of honeybee worker-fate larvae and discovered a protease named PS4 with the highest activity at 72 hours after hatching, which is likely a serine-proteinase. Furthermore, the study found that only royal jelly can inhibit PS4 in worker-fate larvae.

Summary: Honeybees play a crucial role in pollination and hive products, but the loss of managed colonies due to factors like parasites, viruses, pesticides, and climate change has significant economic implications. A pioneer methodology was developed to estimate the economic impact of winter colony losses in Austria, Czechia, and Macedonia, highlighting the importance of honeybees for the agricultural sector beyond subsidies.

Summary: The study found that under semi-field conditions, foraging activity of honey bees on mustard bloom significantly reduced after thiamethoxam spray, with a significant increase in bee mortality. Under field conditions, bee activity remained low up to the 12th day after spray, with less pronounced effects on bee mortality and colony parameters. Thiamethoxam was proven to be toxic to both adult and larval stages of Apis mellifera based on LD50 tests.

Summary: The American beekeeping industry is facing the challenge of reducing colony mortality caused by Varroa destructor mites. Current Integrated Pest Management (IPM) options are becoming less effective due to resistance issues and lack of suitable treatment methods. This study tested the vaporization of oxalic acid as a control measure, but found that it is ineffective in reducing mite populations in brood-rearing periods. Frequent periodic application of oxalic acid did not have adverse impacts on adult honey bees and developing brood.

Summary: There is strong evidence for the significant and unsustainable losses of managed honey bee colonies, raising concerns about the future of pollination services and food security. This study highlights the existence of conflicting life-history trade-offs in workers, which contribute to colony losses. The incorporation of long-living workers in research efforts is crucial to effectively mitigate declines and losses of social insect colonies globally.

Summary: A study shows that malnutrition and insecticide exposure have neutral or antagonistic effects on the reproductive capacity and feeding glands of bumble bees, indicating the presence of regulatory mechanisms related to fitness. Despite negative effects on fitness traits caused by individual stressors, simultaneous malnutrition and insecticide exposure did not have a greater impact, probably due to the resilience of key fitness traits.

Summary: There is clear evidence for a decline in wild insects globally. This decline is caused by various factors such as habitat loss, climate change, pests, pathogens, and environmental pollution. Understanding the interactive effects between these stressors is crucial for mitigating the observed declines. Current studies suggest that the effects of pesticides may outweigh the effects of pathogens on wild bees. Further research, especially in field conditions, is needed to fully understand these interactions and their implications for insect fitness and population dynamics.

Summary: Maintaining agro-food product safety is a significant challenge for tropical countries. This study found that surface dielectric barrier discharge (SDBD) plasma has a high germicidal efficiency against pathogens on the surface of pork cut parts. However, SDBD treatment caused noticeable changes in the overall color of the pork samples, while the surface morphology, structural characterization, and residual nitrites and nitrates remained within safe consumption levels.

Summary: Collaborative brood care is crucial for honey bee colonies, and the hypopharyngeal food glands of workers play a vital role in this process. However, the effects of the ectoparasitic mite Varroa destructor and neonicotinoids on the feeding glands are not well understood. In this study, we found that the combined exposure to Varroa destructor and neonicotinoids had an antagonistic interaction on hypopharyngeal gland size. Individually, Varroa destructor parasitism negatively affected emergence body mass, survival, and gland size, while neonicotinoid exposure only reduced gland size. These findings highlight the need to further investigate the interaction between ubiquitous stressors and their impact on honey bees.

Summary: Beekeepers in the United States have been experiencing high losses of honey bee colonies for over a decade. The Bee Informed Partnership has conducted national surveys since 2011 to document and explain these losses. The survey results from the past three years reveal that winter losses reached a peak of 37.7% in 2018-2019, while summer losses were highest in 2019, at 32.1%. Smaller-scale backyard beekeepers had the highest winter loss rates, and commercial beekeepers experienced higher loss rates during the summer. These findings highlight the temporal variability of colony loss rates in the United States, with a significant effect of beekeeping operation size.

Summary: Bees, especially pollen specialist species, are at risk of decline due to agricultural intensification. However, studies on the effects of pesticides have mainly focused on pollen generalist species. We propose Osmia brevicornis as a new model organism to assess pesticide risk to specialist pollinators, especially in oilseed rape crop, and highlight the importance of considering the foraging preferences and dietary needs of chosen model species in pesticide risk assessment.

Summary: Bee propolis is a natural antimicrobial agent with the potential to replace antibiotics. Despite the existing understanding of its functionality and applications, there is still much research needed in the upstream production and factors affecting its quality. Geopropolis and cerumen, similar to propolis, also hold promise for diverse human applications but require intensive research on their benefits and intricate manufacturing processes.
