Smith), is a generalist pest of food crops and turfgrasses. Insecticides such as diamides provide longer residual control of some grass-feeding caterpillars relative to pyrethroids. The objective was to compare the responses of fall armyworm larvae to residues of commonly used insecticides on hybrid bermudagrass (Cynodon dactylon (L.) × C. transvaalensis Burtt-Davy). A field experiment determined mortality of free-ranging fall armyworms exposed for 1–3 h on turfgrass at 1, 7, 14, 28, and 42 d after a foliar application. A laboratory experiment determined the mortality of larvae fed grass clippings harvested from treated plots at 1, 3, 7, 14, 28, and 42 d after application. Larvae crawled similar or greater distances across bermudagrass treated with bifenthrin and permethrin relative to nontreated grasses. After crawling on bermudagrass treated with chlorantraniliprole or cyantraniliprole 14 d after application, larval mortality was ≥77%. Mortality of larvae fed pyrethroid-treated clippings was ≤40% and no different from control larvae regardless of residue age. Larvae fed bermudagrass with 1 to 7 d old residues of cyantraniliprole or indoxacarb resulted in significantly greater mortality than larvae fed nontreated clippings. No residues of cyantraniliprole or indoxacarb older than 7 d resulted in mortality significantly greater than larvae fed nontreated clippings. Larvae fed chlorantraniliprole-treated clippings of all residue ages produced larval mortality greater than larvae fed nontreated clippings. These experiments support previous reports of extended residual control from chlorantraniliprole against other grass-feeding caterpillar species. The diamides protect turfgrass from larvae better than pyrethroids.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"57 1","pages":"182 - 193"},"PeriodicalIF":0.9,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49335387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the transcriptome data of A. zanthoxylumi, five GST genes were screened and cloned. The transcription levels of the five GST genes in male and female adult head, thorax, abdomen, legs and wings were determined by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) in order to provide a theoretical basis for the functional study of the gene. The results showed that all five GST genes had highly conserved N-terminal domain or C-terminal domain, belonging to two subfamilies of Delta or Sigma. The phylogenetic tree results showed that the evolutionary relationship of GST genes between A. zanthoxylumi, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), and Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae) was the closest; RT-qPCR results showed that the five GST genes were differentially expressed in different tissues and sexes, and its expression level in each tissue of the male was higher than that of the female as a whole, especially in the head. The results of this study can provide basic data for analyzing the mechanism of detoxification resistance of A. zanthoxylumi and provide reference for its biological control and resistance research.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"57 1","pages":"173 - 181"},"PeriodicalIF":0.9,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45093623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore new techniques for prevention and control of this destructive beetle, a novel gene vacuolar ATPase subunit H (V-ATPase H) was chosen as RNA interference (RNAi) target gene. Relative expression of V-ATPase H in different tissues and silencing efficiency in an in vitro RNAi experiment was assayed by using reverse transcription–quantitative polymerase chain reaction. The results indicated that the mRNA abundance of V-ATPase H in the gut was significantly higher than that in fat body, residual body, and hemolymph. Double-stranded RNA (dsRNA) targeting V-ATPase H was able to silence the expression of target gene effectively at 24 h posttreatment. Expression of immunity-related genes was examined after treatment with dsRNA targeting V-ATPase H, and transcript levels were compared with the control. The results showed that RNAi suppression of V-ATPase H inhibited the expression of immunity-related genes.

Silk production by the silkworm, Bombyx mori L., is linked to the quality of the silkworm diet, leading to efforts to nutritionally enrich the mulberry (Morus alba L.) diet of silkworm larvae. Previous studies have established that spermidine, a polyamine, enhances larval growth in B. mori, subsequently increasing silk production. However, its role in improving the nutritional quality of the silkworm diet is not known. In this study, we evaluated the effects of spermidine-treated diet on the nutritional indices, polyamine levels, and antioxidant potential in fifth-instar larvae. We also assessed the effect of consumption of the spermidine-treated diet on the larval gut microbiome, which impacts digestion and assimilation of nutrients. Larvae consuming the spermidine-treated diet showed a significant increase in the efficiency of conversion of ingested food and digested food, intracellular polyamine levels (especially the conjugated and free fraction), antioxidant potential and cell viability, and both diversity and number of bacterial communities. These findings suggest that feeding mulberry leaves fortified with spermidine enhances nutritional efficiency in the B. mori larvae and may represent a method of increasing silk production by B. mori.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"57 1","pages":"12 - 26"},"PeriodicalIF":0.9,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41494865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using gas chromatography-electroantennographic detection (GC-EAD) coupled with electroantennogram (EAG), we found that beet armyworm antennae responded to 8, 11, and 3 volatile organic compounds (VOCs) from noninfected roses, mildew-infected roses, and mildew alone, respectively.

Based on location of the original description (Cano 1894, Naturaleza 2: 377–379) and genetic analyses (Van De Vossenberg et al. 2019, PLos ONE 14(8): e0221182), the origin of the pepper weevil is considered to be Mexico. It is generally more prevalent in warmer climates and a consistent pest of peppers throughout Mexico, Central America, the Caribbean, and the southernmost states in the United States (Riley and King 1994, Trends in Agri. Sci. 2: 109–121). In the United States, the pepper weevil was first reported in Texas in 1904 (Walker 1905, USDA Bur. Entomol. Bull. 54: 43–48). This infestation was suspected to have resulted from importation and repackaging of infested peppers from Mexico (Elmore 1934, USDA Tech. Bull. 447). Elmore (1934) further indicated that movement of infested peppers, picking sacks, and young pepper plants likely moved weevils into new locations. Economically damaging infestations in both field and greenhouse grown peppers have been reported in more northern climates including New Jersey, Canada, the Netherlands, and Italy. These infestations have generally been attributed to importation of infested fruit as they occurred near repacking and processing facilities (Fernandez et al. 2020, J Integ. Pest Manag. 11(1): 1–11; Ingerson-Mahar et al. 2015, J. Integ. Pest Manag. 6(1): 77; Van de Vossenberg et al. 2019).
