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: This study investigated the effects of pyraclostrobin on the development and physiology of honeybee larvae and pupae. The results showed that pyraclostrobin significantly decreased the survival and capped rate of larvae, the weight of pupae and newly emerged adults. qPCR results indicated that pyraclostrobin affected the expression of development-, nutrient-, and immune-related genes in larvae and pupae, decreasing nutrient metabolism and immune competence. These findings suggest that pyraclostrobin should be used cautiously in agriculture, especially during bee pollination.

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: A study revealed that octopamine signaling is necessary for honeybee thermogenesis, and the beta octopamine receptors undergo enormous selective pressure due to adaptation to cold climates. The octopamine signaling might be a key strategy for survival in a changing environment.

Summary: This study investigated the direct toxicity of flumethrin on honeybee larvae and its potential effects on newly emerged adults. The results showed that higher concentrations of flumethrin caused greater damage to honeybee physiology and worker bees. Exposure to flumethrin also affected enzyme activities and gene expression in honeybees. These findings provide valuable insights into the molecular mechanisms of pesticide stress in 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: The herbaceous peony has high value as an ornamental and nutritional plant, and its seeds can be used to produce high-quality edible oil. However, the yield of peony seeds is limited, which can be improved by insect pollinators. In this study, we evaluated the pollination services of honeybees in a peony field and found that honeybees provided effective pollination for peonies, resulting in increased seed number and weight. DNA analysis showed that the pollen collected by honeybees was from peony flowers. These findings suggest that honeybees could be a suitable pollinator for peonies and can be applied in cultivation.

Summary: Sucrose feeding had a minimal impact on the major components of royal jelly, with higher levels of certain amino acids observed in royal jelly obtained from sucrose-fed colonies. However, no significant differences were found in terms of other nutrients or enzyme activity.

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: 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 sublethal dose of sulfoxaflor caused significant alterations in the brain and midgut proteomes of honeybees, with up-regulated proteins mainly involved in energy metabolism and neurotransmitter transport. The major royal jelly protein 1 (MRJP1) was found to play an important role in sulfoxaflor tolerance. These findings provide new insights into the molecular basis of honeybee response to sublethal sulfoxaflor.

Summary: The study demonstrates that the honeybee Apidermin 2 (APD 2) exhibits antibacterial and antifungal activities by inducing structural damage to bacterial and fungal cell walls. The expression of AmAPD 2 in honeybee workers is induced upon microbial ingestion, especially showing high expression in the epidermis and strong response to microbial challenges. The recombinant AmAPD 2 peptide is heat-stable and binds to live bacteria and fungi, ultimately leading to microbial cell wall damage and microbicidal activity.

Summary: The study was conducted in South Wollo Zone, Amhara, Ethiopia, to assess the current beekeeping production system and challenges facing the sector. The community actively engages in beekeeping, primarily for income generation and home consumption. Challenges include bee colony decline, absconding and swarming, lack of training and extension services.

Summary: This review examines the potential effects of desert locust infestation on honeybees in Ethiopia. The study shows that the damage caused by desert locusts to plants can result in the loss of pollen and nectar, leading to a decrease in honeybee brood production, honey yield, and overall health. Additionally, pesticide use to control the locusts can also directly harm honeybees. The study highlights the need for precautions and further research to determine the actual impact on honeybees.
