The white-backed planthopper (WBPH) poses a significant threat to rice crops globally. A bioassay was conducted on three WBPH populations collected from Korean fields assess the effectiveness of five insecticides, including etofenprox and fenobucarb. results showed mortality rate over 97% at recommended concentration for carbamate organophosphate insecticides. However, exhibited less than 40% in all tested with Jindo population showing highest resistance. No mutations were identified voltage-sensitive sodium channel, target site etofenprox, suggesting an alternative resistance mechanism. To explore this, RNA-seq analysis performed identify genes potentially associated Gene expression assessed after treatment two sublethal doses using population. revealed that CYPSF gene, part CYP6 family, consistently overexpressed both treated untreated samples. This observation aligns results, where increased significantly cytochrome P450 inhibitor PBO, indicating may play key role Additionally, distinct gene patterns different concentrations suggest metabolic mechanisms be involved.

For over a decade, diamide insecticides have been effective against lepidopteran pests like beet armyworm, Spodoptera exigua (Hübner, 1808). However, the evolution of resistance poses challenge to their sustainable use. We identified an I4790 M mutation in S. ryanodine receptor (RyR) gene, but its correlation with varied across field-collected Korean populations exigua. RNA sequencing and differential gene expression analysis were performed investigate other mechanisms. Diamide-resistant susceptible strains F1 hybrids compared by mapping RNA-seq reads reference genome. CYP9A40 was as critical due high resistant strains. Synergist bioassays piperonyl butoxide supported role P450s metabolic A strong positive between over-expression levels (up 80-fold) LC
