Summary: Introduced social insects can have negative impacts on native pollinators and ecosystems. In this study, we investigated the morphological variation of the bumblebee Bombus terrestris in Tasmania, Australia and its relationship with environmental conditions. We found weak morphological divergence, with body size associated with urban land cover and proboscis length negatively related to pasture. The adaptability of B. terrestris enables its successful invasion across Tasmania.

Summary: The study found that IRP30 regulates worker egg-laying by affecting the expression of Vg, the size of the ovary and the formation of the oocyte. These findings provide essential information for understanding the mechanisms underlying worker reproductive regulation.

Summary: This study examined the expression patterns of four hexamerin genes in different worker development stages and queen diapause statuses in bumble bees. The results showed that hex 110 has the longest ORF and different hexamerins exhibit varying expression levels at different developmental stages and diapause statuses. Hexamerins may play important roles in queen diapause and metamorphosis of larval and pupal stages.

Summary: Based on recent studies, it has been found that globin-like proteins are present in invertebrates with tracheal respiratory systems. This study investigated the presence of a hemoglobin gene in the natural pollinator Bombus terrestris. The study confirmed that the globin gene is transcribed in all developmental stages, but only in the abdomen, and that its expression decreases with decreasing oxygen levels.

Summary: The study evaluated the stability of reference genes in bumblebees at different developmental stages, identifying RPL13 and RP49 as the most suitable combination. These reference genes are expected to enhance the accuracy of gene expression detection in bumblebees at various developmental stages.

Summary: In this study, the morphology and distribution of the antennal sensilla of Bombus terrestris were analyzed using scanning electron microscopy. Differences in antennal length and sensilla types were found among queen, worker, and male bees. These findings provide valuable information for understanding the pollination behavior and flower preference of B. terrestris.

Summary: In this study, the gut microbiota of workers and queens in the bumble bee Bombus terrestris at different developmental stages were explored using 16S rRNA sequencing technology. The results showed significant differences in morphological indices and gut microbiota composition between workers and queens at different developmental stages. Age was also found to significantly affect the microbial alpha diversity. The findings suggest that the 5th instar larval stage can be used to judge the morphology of workers or queens in bumble bees, and key microbes may be involved in regulating phenotypic variations.

Summary: This study sequenced the DNA of nine Brazilian bumblebee species to construct a detailed phylogenetic tree, and used fossil dating to analyze the timeline of bumblebee diversification. The results showed that the ancestral Bombus lineage originated between 47.08 and 34.27 million years ago in the Holarctic region, and was mainly distributed in the eastern Old World. The Neotropical bumblebees likely originated from North American lineages and colonized South America after 29 million years ago.

Summary: This study compared the morphology of antennae with sensilla in four bumblebee species and found differences in length, type, distribution, and number of sensilla among sexes and species. Additionally, 13 major types of sensilla were observed and the potential functions of the antennae and sensilla were discussed.

Summary: Bumble bees have different types of setal morphologies on their body, with high density of plumose setae on the head and mesosoma. The variation in metasomal plumosity shows strong phylogenetic signal and can be used for species delimitation research. These setae may serve various functions including pollen collection, thermoregulation, and mechanosensory functions. This study provides insights into the development and function of setae in bumble bees.

Summary: The study assessed the distribution of the endemic bumblebee species Bombus pyrosoma in China using MaxEnt, finding that temperature, precipitation, and radiation were key factors influencing its distribution. The results showed that future climate changes will impact the distribution of B. pyrosoma, requiring conservation strategies in high suitability areas.

Summary: Due to a lack of knowledge on kiwifruit pollination requirements in the US, farmers use multiple pollination methods, but this can be costly and inefficient. In this study, we evaluated the contribution of two managed bee species to kiwifruit pollination and found that Bombus impatiens carried more kiwifruit pollen than Apis mellifera. Artificially pollinated kiwifruit flowers resulted in higher fruit set and quality compared to insect and wind pollination. These findings suggest that farmers should focus on artificial pollination for kiwifruit crops and further research should explore other methods.

Summary: Bumble bees are important global pollinators, and consuming sunflower pollen has been shown to reduce infection by the trypanosomatid gut pathogen, Crithidia bombi. This study found that freezer-stored sunflower pollen collected from different years and locations significantly decreased Crithidia infection, suggesting that it can be used as a dietary supplement for managing this pathogen in bumble bee colonies.

Summary: In the context of rapid global change, understanding the impact of environmental stressors on phenotypic variation is crucial. This study assessed the effects of environmental drivers and agricultural intensification on two important pollinator species. The results showed that phenotypic traits can shift in a short period of time after exposure to new field conditions. Latitude and grassland cover were found to partially explain the wing modifications.

Summary: The use of biopesticides against agricultural pests is crucial for sustainable pest management. This study investigated the effects of four commercial biopesticides on Bombus terrestris, both in terms of lethal and sublethal effects. The study found significant worker deaths in the residual contact application of biopesticides, and the number of workers was not affected by biopesticides in this method. Nimbecidine had the most negative impact on the bumblebees. The results highlight the importance of considering the effects of biopesticides on non-target organisms in pest management strategies.
