Chlorantraniliprole has been widely used to controlSpodoptera frugiperda, but it led the development of chlorantraniliprole resistance. Multiomics analysis strains with two extreme traits helps elucidate complex mechanisms involved. Herein, following genome resequencing and application Euclidean distance algorithm, 550 genes within a 16.20-Mb-linked region were identified from chlorantraniliprole-resistant (Ch-R) chlorantraniliprole-susceptible (Ch-Sus) strains. Using transcriptome sequencing, 2066 differentially expressed between Ch-R Ch-Sus Through association analysis, three glutathione S-transferase family four trehalose transporter selected for functional verification. Notably, SfGSTD1 had strongest binding ability is responsible tolerance. The strain also increased intracellular content by upregulating transcription SfTret1, thereby contributing These findings provide new perspective reveal mechanism resistance agricultural pests insecticides.

The fall armyworm (FAW), Spodoptera frugiperda Smith (Lepidoptera: Noctuidae), poses a significant threat to food security, necessitating effective management strategies. While chemical control remains primary approach, understanding the toxicity and detoxification mechanisms of different insecticides is crucial. In this study, we conducted leaf-dipping bioassays assess quinalphos beta-cypermethrin·emamectin benzoate (β-cyp·EMB) on S. larvae. Additionally, assessed response alterations in CarE, GST, MFO, AChE activities sublethal concentrations these over various treatment durations. Results indicated that β-cyp·EMB exhibited higher than frugiperda. Interestingly, highest were observed at 6 h exposure LC
