Assuming the fungus B. bassiana does not adversely affect S. scimitus, the combined application of these 2 agents could enhance the suppression of F. occidentalis. The age-stage, 2-sex life table was used in the present study to evaluate the effects of B. bassiana strain GZGY-1-3 on S. scimitus, mediated through F. occidentalis feeding. When S. scimitus fed on the prepupae of F. occidentalis that had been exposed to the GZGY-1-3 suspension for 24 h, the developmental times of protonymph, deutonymph, and preadult mites were significantly longer and the mites' longevity and fecundity were significantly lower than mites fed on untreated F. occidentalis. The intrinsic rate of increase (r), finite rate of increase (λ) and net reproduction rate (R0) of the mite population were all significantly lower in the treatment where B. bassiana was applied compared to untreated populations. Specifically, the indirect effects of B. bassiana on S. scimitus was mediated through mite consumption of fungus-infected pupae of F. occidentalis. Our results showed that the combined application of B. bassiana and S. scimitus may pose potential risks for the simultaneous biocontrol of F. occidentalis.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144984090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the regulatory effects of diapause on migratory capacity and their underlying mechanisms remain poorly understood. In this study, we systematically examined the flight capacity, flight muscle weight and triglyceride content in adults derived from larvae subjected to varying diapause durations (0, 2, 4, 6, 8, 10 mo). It was confirmed that while different diapause durations had no significant effect on the flight capacity of 1-d-old adults, they could substantially enhance the flight capacity of 3-d-old post-diapause adults. Correlation analysis demonstrated that diapause-induced increases in flight muscle weight and triglyceride content were positively associated with improved flight capacity in 3-d-old adults. These results establish that prolonged diapause durations promote migratory capacity in L. sticticalis, providing critical insights for developing improved monitoring strategies and integrated pest management approaches.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1634-1642"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we examined the responses of S. avenae to seedlings of different wheat cultivars (drought-resistant: Chang-6794, Fan-6, and Yunhan-618 and drought-susceptible: Xinong-585) under three different water treatments. The aim was to assess how wheat drought-resistance and water-deficit stress affect selected life-history traits, honeydew production, and dehydration responses of S. avenae. Our results revealed that second-instar S. avenae presented shorter developmental times on drought-resistant cultivars and with increasing water-deficit stress, showing high plasticity of this trait in response to different environmental conditions. Test aphid individuals from the drought-susceptible Xinong-585 tended to have longer lifespan, higher adult fresh mass, and higher fecundity, compared to those from drought-resistant cultivars. This aphid species tended to produce higher amounts of honeydew on drought-susceptible Xinong-585 than on drought-resistant cultivars. Compared with Xinong-585, this aphid species tended to have higher absolute-water contents on the drought-resistant cultivar Chang-6794 only, showing cultivar-specific effects. Overall, drought-resistant cultivars also tended to be more resistant against S. avenae infestations under all water levels, suggesting a link between drought and aphid resistance in wheat.

However, the patterns of aphid activity remain poorly understood, with systematic monitoring efforts for Aphididae in this region remain insufficient. During 2018 to 2022, multiple methods were used to monitor aphid movements, including a suction trap network in Jilin Province, drones equipped with traps, and adjustable-height yellow sticky traps. In total, 82 aphid species were identified using the suction trap network. In the maize field, 47 and 51 aphid species were captured using drone traps and adjustable-height yellow sticky traps, respectively. Eight aphid species were documented as damaging maize, with field observations of winged and wingless aphids revealing four key pests: Sitobion miscanthi (Takahashi) (Hemiptera: Aphididae), Rhopalosiphum maidis (Fitch), Aphis gossypii Glover, and Rhopalosiphum padi L. Their migration periods, spatial distributions, local population dynamics, and distribution were recorded. In the field, S. miscanthi was occasionally observed during June to October. For A. gossypii, peak activity occurred during June to July, corresponding to the maize ear development stage, whereas R. maidis and R. padi occurrence peaked from August to September, aligning with the maize reproductive growth stage. The study also identified the population sources of these four aphids. Trajectory simulations for S. miscanthi and R. maidis showed annual invasions by migrants from southern China and the Korean Peninsula.

The use of a foundation significantly enhances the efficiency of comb construction. However, commercially available foundation sizes, which match the Langstroth standard frames, are not entirely suitable for Apis cerana cerana Fabricius (Hymenoptera: Apidae), resulting in bees gnawing on the lower edges of the foundation. This study bridges this ecological-technological mismatch by establishing species-specific foundation parameters through morphometric analysis of natural comb architecture. Apis c. cerana primarily starts comb construction in the upper half of the frame during the early stages. The comb pieces were mostly vertically elliptical (nest shape index = 1.4, with a ratio of 0.7 for the horizontal to vertical axis), with the cells predominantly arranged vertically. Based on the structural characteristics of A. c. cerana combs and the principle of economic efficiency, 3 foundation installation patterns were designed. These patterns all promote the comb-building efficiency of A. c. cerana. A comprehensive analysis of the implementation difficulty, construction rate, and regularity of cell orientation revealed that Pattern 3's foundation installation method (horizontal rectangular units: 36 × 10 cm) was determined to be the most efficient and biologically compatible with the comb-building characteristics of A. c. cerana. This study establishes a biomimetic framework for comb foundation optimization in A. c. cerana, demonstrating that horizontally aligned rectangular wax substrates (36 × 10 cm) enhance apicultural efficiency. These findings support an ethology-driven approach to apiculture that aligns with species-specific biological imperatives.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144983925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
