１９９８年在室内用浸叶法测定了棉铃虫对有机磷、拟除虫菊酯、氨基甲酸酯、有机氯和抗生素类５类７种常用农药的毒力反应。结果表明，一至四代棉铃虫对各类型农药的毒力顺序为齐螨素＞功夫＞硫丹＞丙溴磷＞灭多威＞氰戊菊酯＞久效磷。各代棉铃虫对同一种杀虫剂的敏感性呈下降趋势，且杀虫剂抗性上升的幅度与棉田用药水平有密切的关系。与１９９７年的毒力测定结果相比，棉铃虫对氰戊菊酯的抗药性呈上升趋势，相对抗性倍数提高了５．５倍，而对功夫、硫丹的抗药性仍处于稳定状态。
In 1998, the indoor immersion leaf method was used to determine the toxicity of seven kinds of common pesticides to cotton bollworm, including organophosphate, pyrethroid, carbamate, organochlorine and antibiotics. The results showed that the order of toxicity of one to four generations of H. armigera to all kinds of pesticides was mite mites> kung fu> endosulfan> profenofos> methomyl> fenvalerate> monocrotophos. The susceptibilities of cotton bollworm to the same insecticide showed a decreasing trend, and the increasing range of insecticide resistance was closely related to the dosage of cotton bollworm. Compared with the result of virulence test in 1997, the resistance of fenvalerate to H. armigera increased with the relative resistance multiplying 5.5 times, while the resistance to Kungfu and endosulfan was still in a stable state.
