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}

At 24 h after release in choice tests, the number of larvae was greatest on maize ears and lowest on cotton (Gossypium hirsutum L.) leaves among the host plants tested. In nonchoice tests, third-instar larvae that fed on maize leaves and ears had the shortest growth periods (2.05 and 2.2 d, respectively) and the longest on marigold (Tagetes erecta L.) flowers (5.2 d). In oviposition preference tests, maize was the most preferred host, with the greatest number of egg masses deposited in choice and nonchoice tests compared with other hosts. Thus, maize was the most preferred host for fall armyworm in our tests, but fall armyworm may also survive on plants other than maize during the nongrowing season, posing a risk to other economically important crops in its expanded range in India.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"13 4","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139451016","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}

Rob (Gunneridae: Asteraceae). We evaluated the contact toxicity and oviposition-deterrent activity of the extract on adult B. dorsalis, as well as the sublethal effects on survival and reproduction. We found that the A. adenophora extract has significant insecticidal activity, with the 24-h median lethal concentration (LC50) for adults being 26.014 mg/ml. The extract of A. adenophora also showed oviposition inhibition. A residual deterrent effect (28.16%) was evident up to 5 d after treatment. Exposure to the LC25 concentration of the A. adenophora extract caused significant differences in preoviposition and fecundity, decreased adult longevity in the F0 generation, and decreased egg and pupa survival in the F1 generation. The levels of carboxylesterase enzyme activity in adults treated with the extract were significantly lower than those in the untreated controls at 12 h and 24 h. This latter phenomenon could perhaps be an adaptive response to the extract that might reduce its toxic effects in B. dorsalis.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":"9 4","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139256637","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 facilitate chlorantraniliprole resistance monitoring, seedling dip bioassays were conducted in 2013 and 2020 to assess the resistance of 5 field populations of C. suppressalis from Hunan provinces in China. The median lethal toxicity (LC50) of chlorantraniliprole against 3rd–4th instar larvae of field populations ranged from 14.799 to 103.587 mg active ingredient (a.i.)/L. The resistance of C. suppressalis to chlorantraniliprole is increasingly serious in most of the regions in Hunan. The levels of resistance of C. suppressalis to chlorantraniliprole ranged from 11.1-fold to 74.4-fold compared with a susceptible population, respectively. During the 8 years, the resistance level of C. suppressalis to chlorantraniliprole at five monitoring points showed a fluctuating upward trend. The resistance of C. suppressalis to chlorantraniliprole in Hengyang is highest in every year.
