Abstract：Musca domestica are one of important sanitary pests,and can transmit a great variety of infectious diseases that threaten human health.Chemical insecticides has become the main measure for the control of M.domestica due to its rapid and efficient insecticidal effect.However,due to the heavy and frequent application of insecticides,M.domestica have developed resistance to many insecticides.This paper summarizes the resistance of M.domestica to commonly used insecticides in China in recent years,which will provide a reference basis for scientific and reasonable use of insecticides against M.domestica.A total of 82 monitoring sites were counted to carry out resistance studies to cypermethrin,of which 36 sites showed high resistance to cypermethrin,accounting for 43.90％,and 5 sites showed very high resistance to cypermethrin,accounting for 6.10％.A total of 84 monitoring sites were counted to carry out resistance studies to deltamethrin,of which 39 sites showed high resistance to deltamethrin,accounting for 46.43％,and 13 sites showed very high resistance to deltamethrin,accounting for 15.48％.A total of 60 monitoring sites were counted to carry out resistance studies to permethrin,19 sites showed high resistance to permethrin,accounting for 31.67％and 1 site showed very high resistance to permethrin,accounting for 1.67％.A total of 51 monitoring sites were counted to carry out resistance studies to dichlorvos,of which 9 sites showed high resistance to dichlorvos,accounting for 17.65％,and 7 sites showed very high resistance to dichlorvos,accounting for 13.73％.A total of 18 monitoring sites were counted to carry out resistance studies to propoxur,of which 4 sites showed high resistance to propoxur,accounting for 22.22％.A total of 50 monitoring sites were counted to carry out resistance studies to propoxur,of which 5 sites showed high resistance to propoxur,accounting for 10.00％,and 14 sites showed very high resistance to propoxur,accounting for 28.00％.
