Abstract excerpt

The beet armyworm, Spodoptera exigua, is a polyphagous, migratory pest of worldwide importance. It has developed serious resistance to emamectin benzoate and abamectin due to the widespread use of these insecticides in pest control. Previous research demonstrated that the F116V mutation in CYP9A186 confers 265-fold resistance to emamectin benzoate (EB) and 45-fold resistance to abamectin in the WH-EB strain of S....
