Worker bee lifespan directly impacts colony strength, affecting both honey production and pollination efficiency. In this study seasonal, environmental, and nutritional factors influencing the longevity of honeybee workers were assessed under both field and controlled laboratory conditions. Monthly cohorts of newly emerged bees were divided into three groups: (1) marked and released into original hives in the field, (2) caged in the laboratory and fed sugar syrup, and (3) caged and fed sugar syrup with pollen patty. Laboratory conditions were maintained at 30 °C and 60 % relative humidity. Results showed that worker bees lived significantly longer in laboratory settings than in the field. Among field-released bees, longevity peaked in September and was shortest for bees emerging in August. These patterns suggest strong monthly effects, likely driven by abiotic stressors such as extreme summer heat, humidity, food resource scarcity, and agrochemical exposure, as well as biotic stressors like labor demands and pathogen presence. In the laboratory, bees receiving pollen patty alongside sugar syrup lived longer than those fed sugar syrup alone, underscoring the importance of dietary protein. The study highlights how environmental and nutritional factors shape honeybee longevity and suggests colonies may be especially vulnerable in late summer. Findings emphasize the need for improved management practices, such as supplemental forage and nutrition, to enhance colony resilience. Understanding the seasonal dynamics of worker bee survival is crucial for beekeepers, researchers, and agricultural stakeholders aiming to maintain healthy bee populations and ensure reliable pollination services.</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 4","pages":"Article 102498"},"PeriodicalIF":1.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145516478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we identified an Hsp70 gene (<em>AglyHsp70</em>) from the soybean aphid genome and investigated its expression profile and role in stress tolerance under thermal and insecticide challenges. Sequence alignment and phylogenetic analysis revealed that AglyHsp70 shares strong homology with Hsp70 proteins from other insect species.

Exposure to imidacloprid significantly upregulated <em>AglyHsp70</em> expression in a concentration- and time-dependent manner. Moreover, RNAi-mediated knockdown of <em>AglyHsp70</em> markedly increased soybean aphid mortality under heat stress and at specific concentrations of imidacloprid. Collectively, these findings demonstrate that <em>AglyHsp70</em> plays an essential role in stress tolerance against both thermal and chemical stressors in <em>A. glycines</em>.

Five-step serial dilutions of the recommended field concentration (RFC) were used for acute oral and contact toxicity assays. ICP-OES was used to quantify copper residues in lab-exposed and field-collected bees, while multi-residue pesticide analysis was performed with LC-MS/MS and GC–MS/MS.

Field-collected bees exhibited higher copper bioaccumulation than control, comparable to lab-exposed bees with a 10<sup>−2</sup> RFC dilution, which remained well under the LC<sub>50</sub>. This implies that copper alone is not the cause of the witnessed phenomenon. Among detected pesticides, dinotefuran exhibited high HQ values, exceeding elevated risk threshold. Triflumizole and buprofezin showed minimal risk; however, triflumizole was considered likely to interact with dinotefuran, with their short half-lives potentially contributing to increased toxicity in bees. The combination of copper, dinotefuran, and triflumizole suggests potential interactive toxicity contributing to the observed mortality.
