Drought-resistant wheat cultivars have been developed to increase yield under water-deficit conditions. However, the effects of drought-resistant wheat on responses of S. avenae under water deficit are still unknown. 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. Our results provide insights into complex interactions between water stress levels and wheat drought resistance and have significant implications for wheat production and the development of integrated management programs for aphids in the context of climate change.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1599-1607"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512951","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 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. These findings are critical for predicting aphid outbreaks in the region and for informing maize cultivation strategies in affected areas.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1742-1751"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144577445","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}

This study aimed to investigate the functional response of A. baccarum to two common raspberry pests, Aphis idaei van der Goot and Neotetranychus rubi Trägårdh. In controlled laboratory conditions, six densities of A. idaei nymphs (2, 4, 8, 12, 16, and 24) and adult N. rubi females (2, 4, 8, 16, 24, and 32) were introduced in separate functional response experiments. Furthermore, the prey preference of A. baccarum on the two species was investigated when 5 A. idaei nymphs and adult N. rubi females were offered simultaneously to the predator. Anystis baccarum exhibited type II functional response to both prey, with capture rate for A. idaei higher than N. rubi. In addition, A. idaei was more likely to be consumed by A. baccarum than N. rubi. While promising as a biocontrol agent, the searching behavior, cannibalistic nature, and long generation time of A. baccarum suggest that it should not be relied upon solely for pest management in raspberry. Further studies on synergistic interactions with other biocontrol agents are recommended.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1536-1543"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12397967/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144287665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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}

This review addresses this critical knowledge gap by examining the genetic, behavioral, and physiological mechanisms that enable M. persicae to adapt to various host plants. The formation of biotypes through genetic adaptation, including color polymorphism and detoxification processes, is explored as a key factor in the pest's survival and proliferation. Additionally, we analyze the behavioral strategies M. persicae employs in host selection and feeding preferences, influenced by host plant traits. Physiological adaptations, such as changes in digestive enzymes and life cycle modifications, further contribute to the aphid's capacity to overcome plant defenses. The review also considers the impact of environmental and host plant factors on these adaptations, providing a comprehensive understanding of the complex interactions between M. persicae and its hosts. By integrating these insights, the review proposes implications for the development of more targeted and sustainable pest management strategies. This work enhances our understanding of host adaptation in M. persicae and underscores the need for novel approaches in controlling this resilient pest, ultimately contributing to the advancement of integrated pest management (IPM) practices.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1449-1462"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144217954","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}

While synthetic miticides are valuable for Varroa management, high reliance on these compounds has selected for miticide-resistant Varroa populations. To enable more sustainable Varroa management and provide options when synthetic miticides such as amitraz fail, effective Integrated Pest Management (IPM) approaches are urgently needed. Here, we show that organic miticides (oxalic acid, \"OA\"; and hops beta acids) can achieve high efficacy against Varroa when strategically combined with a widely used cultural control (starting new colonies, \"splits,\" with queen cells). This common splitting practice acts as a cultural control by temporarily reducing the amount of brood (developing bees) in colonies. This forces Varroa mites out of the protected environment of brood cells and on to adult bees-where they can be more effectively targeted with miticides. Based on Varroa infestation rates of adult bees, we determined that the organic miticide treatments OA dribble (75.5% efficacy), 5× OA dribble (82.2%), and HopGuard (82.7%) were significantly more effective than no treatment and provided comparable efficacy to amitraz-based miticides. In contrast, OA vapor (44.3%) did not provide effective Varroa control. Based on observations of queen and colony success, colony strength measurements, and hive weights, none of the organic miticides showed signs of harming colonies. Therefore, this combination of cultural and chemical control provides an additional opportunity for beekeepers to implement IPM for more effective and sustainable Varroa management.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1495-1503"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12412293/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, life table parameters such as the net reproductive rate (R0), and intrinsic rate of increase (r) in treated groups were reduced, while the mean generation time (T) was extended in these treatments. Enzyme activity assays displayed that these insecticides caused different detoxification enzyme activities variations, indicating that CarE, MFO, and GST may play key roles in the detoxification of the tested insecticides in H. armigera, respectively.
