Objectives. High dependency on pesticides could cause selection pressure leading to the development of resistance. 0is study was conducted to assess the resistance of the house fly, Musca domestica, to five insecticides, namely, permethrin, deltamethrin, beta- cypermethrin, propoxur, and dichlorvos, in Zhejiang Province. Methods. Field strains of house flies were collected from the 12 administrative districts in Zhejiang Province in 2011, 2014, and 2017, respectively. Topical application method was adopted for the bioassays. 0e probit analysis was used to determine the median lethal doses with the 95% confidence interval, and then the resistance ratio (RR) was calculated. 0e insecticides resistance in different years and the correlations of the resistance between different insecticides were also analyzed.
