The results of organismal movement impact multiple dimensions of fitness, population dynamics, and functional interactions. As such, the study of movement is critical for understanding and conserving species. Bumble bees (Apidae: Bombus spp.) offer a powerful system to study multiple complexities of movement within a functionally important clade. Their life history includes distinct social and solitary phases, substantial intraspecific variation in body size, and multiple modes of movement behavior. These traits allow investigations of diverse concepts at multiple scales and during contrasting behavioral and motivational states-from individuals, to colonies, to populations, and among species. Despite extensive study as model organisms of fine-scale movements and optimal foraging theory, understanding of landscape-scale movements is more limited. This knowledge gap is especially troubling given global pollinator declines because such dispersive movements fundamentally affect how populations respond to landscape transformation, climate change, and restoration efforts. To build toward a refined understanding of the bumble bee movement, inform research, and assist conservation programs, we review foraging and dispersal movement across life stages and castes. Using an ontogenetic approach, we compare the movement motivation and capacity of individuals throughout colony development. Despite the growth in recent literature, much remains to be learned about the bumble bee movement, especially dispersive life stages. Focused effort on how movement varies with individual state such as nutrition and age, and comparative studies of species would all fill knowledge gaps with high potential to improve bee conservation and research.","PeriodicalId":8076,"journal":{"name":"Annals of The Entomological Society of America","volume":"118 3","pages":"175-188"},"PeriodicalIF":3.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095912/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we characterize behavioral, ecophysiological, and morphological traits of adult C. hemorrhagica living on hot springs in YNP compared to adults living in a non-hot spring environment in Idaho. Individuals in YNP behaviorally warmed and cooled themselves at surprisingly different frequencies than those in Idaho, with YNP individuals infrequently cooling themselves even though surface temperatures were greater because of geothermal activity and consequent bottom-up heating of individuals compared to the saline-flat habitat in Idaho. After a series of lethal thermal maxima and internal body temperature experiments, our results suggest that an explanation for the differential behavior is that the adult in YNP has evolved increased heat reflectance on the ventral portion of its abdomen. This increased heat reflectance seems to be caused by a physical feature as part of the exoskeleton's ventral abdominal plate, which likely protects the beetle by serving as a heat-resistant shield. The extreme conditions in YNP seem to have selected C. hemorrhagica to be among the most thermophilic insects known.","PeriodicalId":8076,"journal":{"name":"Annals of The Entomological Society of America","volume":"118 3","pages":"237-247"},"PeriodicalIF":3.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095910/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these markers, the vasa (vas) orthologues, which encode ATP-dependent RNA helicases, are highly conserved. Previous studies have examined asexual (parthenogenetic) and viviparous embryos of the pea aphid Acyrthosiphon pisum using a cross-reacting Vas antibody. This study utilized a specific antibody against Ap-Vas1, a Vas orthologue in the pea aphid, to gain new insights into germline development. The Ap-Vas1-specific antibody facilitates earlier detection of germ-plasm assembly at the oocyte posterior, challenging the previous assumption that germ-plasm assembly begins only at the onset of embryogenesis. Treatment of oocytes and early embryos with cytoskeleton inhibitors suggests that germ-plasm assembly primarily depends on actin, in contrast to the fly Drosophila melanogaster, where both actin and microtubules are essential. Since pea aphids lack an orthologue of osk, which encodes the protein Osk responsible for anchoring Vas to the germ plasm in Drosophila, this suggests that pea aphids employ distinct mechanisms for osk- and microtubule-independent formation of the germ plasm. Moreover, the clustering of germ cells into germarium-like structures in the extraembryonic region before entering the embryos suggests a gonad formation process different from that in Drosophila, where germ cells begin to cluster into germaria after settling within the embryonic gonads. Therefore, the analysis of the Ap-Vas1 distribution provides a deeper understanding of germline development in asexual pea aphids, uncovering novel aspects of parthenogenetic and viviparous reproduction in insects.","PeriodicalId":8076,"journal":{"name":"Annals of The Entomological Society of America","volume":"118 3","pages":"229-236"},"PeriodicalIF":3.0,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12095909/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Verified host records are few in number and limited in scope. In order to understand host specialization, more records are needed.

The specialist larval parasitoid wasp, Ganaspis brasiliensis (Ihering), was recently approved in Europe and the United States for classical biological control releases against D. suzukii. Rearing methods are essential for supporting innundative releases but current methods using fresh fruit are costly and susceptible to variation in host quality. To develop an artificial rearing system, we first compared the performance and development of D. suzukii and G. brasiliensis on fresh raspberries and blueberries and then on various artificial diet shapes and volumes. Drosophila suzukii had 1-2 days shorter development times in raspberry than blueberry, whereas Ganaspis adult development time was similar in both fruit and averaged 25 days. Parasitism rates by G. brasiliensis were significantly higher in blueberry than raspberry in both small and large resource patches. We found that D. suzukii preferred to lay eggs in full sphere diet shapes than in flat diet circles or semisphere diet, and in the first trial with wasps parasitism was only found on D. suzukii larvae in the full sphere shape of raspberry diet. Comparison of parasitism on full sphere raspberry and blueberry diets found higher parasitism in raspberry compared to blueberry diet. Our results indicate potential for further improvement of artificial rearing systems for G. brasiliensis to allow more cost-effective and reliable rearing for biological control programs.","PeriodicalId":8076,"journal":{"name":"Annals of The Entomological Society of America","volume":"118 1","pages":"88-99"},"PeriodicalIF":3.0,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11725758/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142982564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
