WANG Bingsheng
Abstract：Objective To understand the resistance status of Musca domestica to commonly used insecticides in Jinnan,Tianjin,so as to provide technical guidance for the scientific use of insecticides.Methods According to the topical application method of GB/T 26350-2010,the insecticide resistance of M.domestica was determined.Results In 2017,the resistance ratios of M.domestica were permethrin 9.64(low resistance),methylpyrimidine 11.05(moderate resistance),lambda-cyhalothrin 20.09(high resistance),beta-cypermethrin 91.33(high resistance),deltamethrin 158.50(high resistance),and propoxur＞352.94(high resistance).In 2020,the resistance ratios of M.domestica were permethrin 11.61(moderate resistance),lambda-cyhalothrin 17.5(moderate resistance),DDVP 41.18(high resistance),deltamethrin 116.67(high resistance),beta-cypermethrin 181.67(high resistance),and propoxur＞352.94(high resistance).Conclusion Government departments should strengthen the management of insecticides,and suspend the purchase and use of insecticides that have developed high resistance such as propoxur,deltamethrin,and beta-cypermethrin.It is necessary to scientifically and rotating use insecticides that have developed moderate resistance such as permethrin,lambda-cyhalothrin,and organophosphates,or introduce new insecticides with new mechanisms of action to delay the development of resistance.
