Unraveling Key Amino Acid Residues Crucial for PxGSTs1 Conferring Benzoylurea Insecticide Resistance in .

The widespread use of benzoylurea insecticides (BUs) has led to significant resistance issues in various agricultural pests. Previous studies have demonstrated that the overexpression of sigma glutathione S-transferase 1 (PxGSTs1) can confer resistance to novaluron in ; however, the underlying molecular mechanism remains unclear. This study investigates the role of glutathione S-transferase PxGSTs1 in mediating resistance to BUs in .
