This insect significantly damages glossy privets and ash trees in most regions of China. The fatty acyl-CoA reductase (FAR) gene is a crucial enzyme in the cutin, suberine, and wax biosynthesis pathways in these insects and also in fatty acid metabolism. Herein, a synthesized double-stranded RNA of the FAR gene in E. pela (dsEpFAR) was used to explore the effects of dsEpFAR on the expression of EpFAR and secretion of wax and development of E. pela. The results showed that a high concentration of dsEpFAR could cause mortality of male nymphs. After a male nymph was treated with a low dose of dsEpFAR, the transcription level of EpFAR was significantly downregulated, the expression level of EpFAR protein was reduced, and the quantity of wax was markedly decreased, suggesting that EpFAR is a key gene in the biosynthesis of wax and that dsEpFAR can interfere with the gene EpFAR and disrupt the process of wax secretion. The growth and development of male nymphs were also significantly influenced by dsEpFAR treatment, leading to a significantly decreased weight and earlier nymph-to-pupae transition. The findings enhance the molecular understanding of male E. pela wax secretion and facilitate the development of EpFAR-based interference with wax secretion for the integrated management of male E. pela.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"60 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147919717","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}

Our study (1) examined the preference of B. tabaci for G. uralensis Fischer ex de Candolle, G. glabra L., and G. inflata Batalin through caged trials; (2) identified the volatile organic compounds (VOCs) released by the three Glycyrrhiza species using headspace gas chromatography–mass spectrometry (HS-GC-MS); and (3) screened the olfactory behavior responses of B. tabaci to the key VOCs identified. The caged host preference trial showed that B. tabaci had a clear preference for G. uralensis over G. inflata and G. glabra. Through HS-GC-MS analysis, we identified 26, 33, and 31 VOCs from G. uralensis, G. glabra, and G. inflata, respectively. (3Z)-Hexen-3-ene-1-yl acetate, trans-3-hexen-1-ol, cis-3-hexen-1-ol, 3-carene, and β-pinene were selected for further olfactory response assays on the basis of variable importance projection values and quantity differences. From these, we learned that cis-3-hexene-1-ol and trans-3-hexene-1-ol, abundant in G. uralensis, attract B. tabaci, whereas 3-carene and β-pinene, abundant in G. inflata, repel B. tabaci. The different VOCs from these three species of licorice may be primary factors affecting the preference for and feeding on cultivated licorice by B. tabaci. Our results will facilitate studies on the potential of using selected VOCs for managing B. tabaci, perhaps in push–pull strategies of their use against the pest.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"60 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894847","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}

With the extensive use of insecticides, A. gossypii in Xinjiang has developed high levels of resistance to a variety of insecticides. Afidopyropen is a new biogenic insecticide that is effective against insects with piercing-sucking mouthparts and has no cross-resistance with any commonly used insecticides in cotton fields. However, to our knowledge, the risk and stability of resistance of A. gossypii to afidopyropen and its detoxification enzymes under high selection pressure have not yet been elucidated. In this study, resistant A. gossypii specimens were selected with the cotton leaf-dipping method under laboratory conditions, and the realized heritability of A. gossypii resistance to afidopyropen was calculated using domain trait analysis. After 18 successive generations of selection for afidopyropen resistance, a resistant population with a median lethal dose (LC50) of 9.006 mg/L was obtained; the resistance ratios had increased 23.033 times. The realized heritability was 0.063, and a 10-fold increase in resistance required only 20–26 generations when mortality was 60–80%. The 15th generation of the resistant strain had some resistance instability, and glutathione S-transferases played an important role in the detoxification metabolism of afidopyropen. The results of this study provide a basis for application of afidopyropen and management of A. gossypii resistance.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"59 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880076","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}

Two key pests of cotton in the midsouthern United States are the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae), and bollworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae). A suite of highly effective synthetic insecticides is typically used for control of these pests. However, it is unclear how the combined management of these two insect pests with biological insecticides impacts the economics of cotton production. To address this shortcoming, we conducted a field experiment in the Mississippi Delta over 2 yr to study the effects of synthetic and biological insecticides for control of the tarnished plant bug and bollworm on cotton yield. The results indicated the control of tarnished plant bug with synthetic insecticides had the most significant impact on cotton yield and net returns. The conventional tarnished plant bug treatment also significantly increased bollworm density and damage, but these increases did not significantly alter yield or net return in non–Bacillus thuringiensis (Bt) or Bt cottons. The economic benefit of a conventional approach to tarnished plant bug control with synthetic insecticides was US$438.07/ha in non-Bt and $700.88/ha in Bt cotton relative to those treated with a biological insecticide. The biological insecticides used for this study were ineffective at significantly altering yield or net return. However, for insect management in cotton to be sustainable, alternatives must be found to complement conventional synthetic insecticides.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"62 10","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139451635","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}

Migratory locusts, Locusta migratoria manilensis (Meyen) (Orthoptera: Acrididae), are notorious for their destructive impact on crops. Traditional morphological methods often face limitations in distinguishing closely related species and require taxonomic expertise. However, the emergence of DNA barcoding as a powerful tool for species identification has revolutionized the field of entomology. DNA barcoding utilizes a standardized DNA sequence, a molecular barcode, which serves as a distinct genetic signature for rapid and accurate species identification. In this study, DNA barcoding techniques were employed to identify and differentiate the migratory locust subspecies manilensis, in both its solitary and gregarious forms, as well as to determine its phylogenetic relationship with other related species within the Acrididae family. GenBank reference sequences were used to identify the locusts at the molecular subspecies level. Although the COI marker did not exhibit significant differences between the solitary and migratory forms, it was valuable in resolving the identification of L. migratoria subspecies. This lack of significant differences may be attributed to limited genetic variation of COI at the subspecies level and substantial genetic similarities between the solitary and migratory forms, likely stemming from a recent common ancestor. Nonetheless, using COI remains beneficial for subspecies identification in migratory locusts.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"49 16","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139451669","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}

A major whitefly control failure occurred in the state of Georgia in 2017 when B. tabaci–induced economic losses in horticultural and field crops surpassed approximately US$160 million. Vegetable growers have historically used imidacloprid for whitefly management, which likely led to the insecticide control failures of whiteflies in spring vegetables. Despite this, only a single site documentation of imidacloprid resistance in adults from 2007 in Georgia exists, making the current status unknown. Thus, it is likely that Georgia has an ongoing risk of imidacloprid-resistant B. tabaci infestations. No multicounty, extensive survey for imidacloprid dose response in whitefly exists for the state of Georgia. Therefore, an adult mortality bioassay of a range of imidacloprid concentrations was used to evaluate B. tabaci populations from several counties in South Georgia, where most of these economic losses occurred. This included a maximum dose concentration representing the current highest labeled rate. Dose response to the insecticide was not uniform across locations, with whiteflies in several areas displaying unexpected susceptibility to imidacloprid. Median lethal concentrations (LC50s) ranging from 0.02 to 196.05 mg of active ingredient per liter in Georgia whitefly populations were substantially lower than the reference Florida whitefly population. This baseline information for the state is critical to future evaluations of this insecticide in resistance management programs.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"76 9","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139388272","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}
