Abstract：Objective To understand the current status of insecticide resistance of Musca domestica in the human environment of Huainan,so as to provide theoretical basis for scientific fly control.Methods M.domestica were collected from farmers' markets,restaurants,supermarkets,garbage transfer stations and residential areas in five districts of Huainan in 2023,including Tianjia'an District,Datong District,Xiejiaji District,Bagongshan District and Panji District.The topical application method was used to evaluate the resistance of M.domestica to six commonly used insecticides.And the data were analyzed using the SPSS 25.0 software for the virulence regression equations,LD50 and 95%confidence interval(CI).Results For M.domestica,the LD50 of deltamethrin,beta-cypermethrin,dichlorvos,chlorpyrifos,tetramethrin,propoxur were 0.249 5,0.754 6,0.305 6,0.220 7,＞30,＞30 μg/mosquitoes,and the resistance ratios were 356.43,87.74,26.81,76.10,＞449.78,＞15 789.47,respectively.Conclusion At present,M.domestica in Huainan have developed high resistance to the six commonly used insecticides.It is recommended to stop or reduce the use of these insecticides.In the future,it is necessary to continue to strengthen resistance monitoring,and use insecticides scientifically and rationally in order to delay the occurrence and development of insecticide resistance,and improve the effectiveness of fly control.
