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.
