Insecticide resistance-associated mutations in chinese Spodoptera exigua populations: prevalence characteristics and AS-PCR rapid detection validation.

Abstract excerpt

The beet armyworm, Spodoptera exigua, a notorious agricultural pest, poses an increasing threat in China. This study aimed to elucidate the frequency of resistance-associated mutations across 11 S. exigua populations in China and assess the effectiveness of allele-specific PCR (AS-PCR) for rapid mutation detection. We employed sanger sequencing to identify reported mutations in key resistance genes including...
