H. armigera can be effectively controlled using abamectin, chlorfenapyr, chlorpyrifos and spinetoram in Hebei and Shandong provinces. The present study demonstrated that the relative expression level of GSTs1, GSTd1, CYP9A14, CYP9A17V2 and CYP337B1 genes were significantly correlated with the resistance ratio to indoxacarb, metaflumizone and carbosulfan in field H. armigera.
