Detoxification genes are crucial to insect resistance against chemical pesticides, yet their expression may be altered by exposure biopesticides such as spores and insecticidal proteins of Bacillus thuringiensis (Bt). Increased enzymatic levels selected detoxification genes, including glutathione S-transferase (GST), cytochrome P450 (CYP450), carboxylesterase (CarE), were detected in chlorantraniliprole (CAP)-resistant strains the diamondback moth (DBM, Plutella xylostella) from China when compared a reference susceptible strain. These CAP-resistant DBM displayed distinct patterns GST 1, CYP6B7, CarE-6 after treatment with CAP Bt pesticide (Bt-G033). In particular, gene analysis demonstrated significant upregulation CYP6B7 response treatment, while same was downregulated following Bt-G033 treatment. Downregulation using RNAi resulted increased susceptibility resistant strains, suggesting role this phenotype. However, pretreatment sublethal dose inducing downregulation did not significantly increase potency strains. results identify involved metabolic demonstrate how is affected Bt-G033.

Abstract BACKGROUND Resistance management in pesticide use is critical, yet grower practices, especially mixing motivations, diverge from theoretical frameworks. This study analyzes 30 years of Arizona cotton growers’ practices and pest manager insights to understand trends. RESULTS Growers predominantly mix pesticides for spectrum or efficacy, not resistance management. highlights a gap between theory practice, emphasizing the complexity real‐world dynamics. A shift over time towards selective insecticides integrated (IPM), supported by extension education, has reduced reliance on broad‐spectrum increased opportunities conserve natural enemies key pests. frequency insecticide use, mutual goal both IPM The availability adoption products with diverse modes action, along resulting increases biological control refuges, likely delayed prevented resistances without emphasis using mixtures specifically In disrupted system exclusively dependent (1991–1995), 75% ± 5% area was sprayed these materials. With insecticides, few are used today only 36% 3% (2015–2020). CONCLUSION Although relevance, it diminishing stable systems action adherence moderation principles. guidance prioritizes multi‐crop refuges Integrated research targeting professional managers, pivotal advancing designed prevent mitigate resistance. © 2024 Society Chemical Industry.

Diptera and Lepidoptera species have the highest levels of insecticide resistance, mechanism drug resistance has been studied in detoxification metabolism genes such as P450, GST, EST, ABC. Since Bactrocera dorsalis are resistant to a variety chemicals, pattern investigated from aspects genes, enzymes, intestinal symbiotic bacteria, synergists world. In this study, 51 149 were annotated Suppression Subtractive Hybridization (SSH) library, 12 candidate related beta-cypermethrin screened quantitatively expressed library.
