Legumes (family Fabaceae), unlike grapevines (Vitis vinifera L.), are preferred feeding and reproductive hosts for S. festinus. Here, we analyzed the development and behavior of S. festinus on snap beans (Phaseolus vulgaris) in comparison to alfalfa (Medicago sativa) and grapevines, with an emphasis on colony establishment and population growth. Snap beans supported all stages of S. festinus development, promoting feeding, reproduction, and colony establishment, as well as supporting a faster life cycle, particularly on detached trifoliates in controlled environmental chambers, compared with alfalfa. Moreso, social aggregation of S. festinus adults was observed on snap bean plants with the petiole as a preferred feeding site. A preference toward grapevine petioles was also seen, though their survival and aggregation behaviors drastically declined on this nonlegume host. Dissecting the alimentary canal of S. festinus revealed more orange, refractive oil droplets, and air bubbles in specimens from grapevine compared to specimens from snap bean or alfalfa, suggesting possible disruptions in digestive processing or nutritional deficiencies with the former host. Together, our findings highlight snap bean as an ideal host for rearing populations of S. festinus to be used in grapevine red blotch virus transmission studies.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610735","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, they also cause extensive damage in live trees and pose serious risks to tree health as a result. The urban tree canopy in areas with established populations of Coptotermes are therefore at risk of loss of trees over time, and many urban forests within municipality parks in their introduced range may experience tangible canopy alteration. This can have wide-reaching negative impacts on the ecology of these parks and to the public that utilize them. This 5-yr long study utilized eight parks (1,304 trees) to demonstrate how a simple visual monitoring/bait approach can identify and eliminate termite colonies infesting trees and maintain minimal termite activity within public green spaces. Here, we demonstrate that the systematic direct application of an experimental above-ground chitin synthesis inhibitor (CSI) bait formulation to trees can eliminate termite activity and protect trees. However, owing to high termite pressure, colony reinfestation is likely over time, and municipalities may have to establish perennial programs that would include regular monitoring and treatment as needed. Such a long-term strategy would minimize tree loss, while using a termite-specific formulated pesticide with a low amount of active ingredient. This pilot study demonstrates that it can be achieved, but ultimately, the success of this approach relies on technically competent staff that can readily identify the signs of active Coptotermes infestation in trees and access to above ground CSI bait formulations.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610724","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}

(Lepidoptera: Bombycidae). Sur8 functions as a positive regulator of the RAS-MAPK signaling cascade, which plays an essential role in regulating cocoon silk production in Bombyx mori. However, the specific functions of BmSur8 in silkworms have not been fully elucidated. In this study, we demonstrate that BmSur8 is a highly conserved gene expressed across all life stages and various tissues at the third day of the fifth instar larvae (L5D3) stage in Bombyx mori. Knockout of the BmSur8 gene results in a 15.2% reduction in silk yield in females and a 13.4% reduction in males, with the cocoon layer rate in females decreasing by 3.8%. Through transcriptomic analysis of posterior silk glands (PSGs) at L5D3 stage from ΔBmSur8 mutants and Nistari controls, as well as mass spectrometry analysis of BmSur8-interacting proteins in BmN cells, we find that BmSur8 potentially interacts with BmEtfb and regulates the expression of BmCDA and BmjunD, thereby participating in material and energy metabolism. This study provides a comprehensive analysis of the function of BmSur8 in metabolic pathways and offers theoretical insights and experimental data for researching silkworm cocoon silk quality and yield, as well as for breed selection and breeding.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610736","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}

Given the need to establish new management tactics for B. tabaci, this study aimed to evaluate the effect of essential oils (EOs) from Syzygium aromaticum (Myrtaceae), Cymbopogon citratus (Poaceae), Cordia verbenacea (Boraginaceae), Callistemon sp.

The EOs of S. aromaticum and C. citratus were the most promising overall, exhibiting significant ovicidal activity, strong repellency, and deterrent effects on oviposition. Additionally, S. aromaticum and C. citratus EOs, and B. dracunculifolia EO, caused high nymphal mortality, while B. dracunculifolia EO stood out with the highest adult mortality.

(Hemiptera: Cimicidae), has become a well-established pest in houses within the United States. This is partly because bed bugs have been so successful at invading the many void spaces that exist in homes. Fumigation with sulfuryl fluoride (Vikane) at the 1.9× dosage rate is one of the few control methods that can access all bed bug harborage spaces in these homes and potentially eliminate all insecticide-resistant bed bug life stages in a single treatment. The objective of this study was to evaluate the labor costs and efficacy of two different home sealing methods that are typically used when conducting structural fumigation: covering the home with a tarpaulin or sealing cracks of doors and windows with tape (\"tape-and-seal\" method). It was found that the tarpaulin fumigations required a significantly greater number of labor hours (42.6 ± 2.3 SEM) than the tape-and-seal fumigations (24.2 ± 5.0 SEM) due to the more detailed preparation requirements (requiring more laborers) and longer fumigant holding periods. Only the tarp fumigations achieved 100% mortality of sentinel bed bug eggs. In the tape-and-seal fumigations, hatching was observed for 22% of the eggs, with 10% of the hatched nymphs surviving. This lack of complete bed bug mortality was because two tape-and-seal fumigations were unable to reach the 1.9× dosage rate.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593268","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}

Heat shock protein 70 (HSP70) family members serve as key components in insect molecular networks under heat stress. However, studies remain limited on this pest's tolerance to persistent high temperatures and the role of HSP70 under such stress conditions. In this study, extreme heat treatment (EHT; daily cycle of 31 °C (6 h), 34 °C (6 h), 37 °C (6h), and 34 °C (6 h)) drastically reduced H. cunea larval survival, preventing life cycle completion. Heat treatment (HT; daily cycle of 28 °C (6 h), 31 °C (6 h), 34 °C (6 h), and 31 °C (6 h)) during early stages had minor effects on larval development, whereas exposure during late larval stages shortened developmental duration, reduced fecundity, and decreased fitness. To explore the molecular mechanisms, four HSP70 genes of H. cunea were cloned and characterized. Phylogenetic analysis revealed high conservation among HcHSP70s, showing a close relationship with those from Noctuidae insects. HcHSP70 transcripts were significantly upregulated during heat stress, exhibiting diurnal fluctuation with peak expression at specific times. These results show that H. cunea can tolerate moderate heat stress, but pre-reproductive thermal stress reduces fecundity. The upregulation of HSP70 expression contributes to enhanced thermotolerance in this pest. Overall, this research provides a reference for population prediction of H. cunea in regions with increasing heat stress.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593249","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":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-07","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}
