Abstract：Objective To understand the resistance of Musca domestica to commonly used insecticides in different counties or districts of Lianyungang City,so as to provide data support for rational selection,use of insecticides and decision-making of administrative departments.Methods Based on the Implementation Plan for Monitoring the Resistance of Vector in Lianyungang City,adult flies were captured by using fly nets,and the resistance of Musca domesticato insecticides were determined by using the topical application method in 2023.Data Processing System software was used to statistically analyze the data.Results Musca domestica in Haizhou District and Lianyun District were sensitive to dichlorvos,while Musca domestica in Ganyu District and Guanyun County were resistant to five insecticides.The highest resistance ratios of Musca domestica to deltamethrin,beta-cypermethrin,dichlorvos,phoxim,and dinotefuran were 113.64,18.50,11.17,54.74 and 11.60,respectively.Conclusion The use of deltamethrin for fly control should be restricted or stopped in Lianyungang City.Rotational and combine application of insecticides are prefer to delay the occurrence and development of the fly resistance.Comprehensive control measures should be implemented,chemical insecticides should be reduced,the environmental management and surveillance of insecticide resistance should be strengthened.
