Abstract：Objective To understand the density,population composition and seasonal fluctuations of flies in Liaoning Province in 2021,to provide a reference for scientific prevention and control of flies.Methods From May to October 2021,four kinds of places including residential areas,restaurants,greenbelts and farm produce markets were chosen for investigation.The cage trapping methods were used for the surveillance.Results The density of flies in Liaoning Province in 2021 was 4.61 flies/(cage·h).Lucilia sericata was the dominant species accounting for 36.85%,followed by Muscina stabulans(18.13%),Musca domestica(17.10%)and Sarcophagidae(12.41%).In different surveillance habitats,the density of flies in greenbelts was the highest,as much as 5.80 flies/(cage·h),while the residential areas held the lowest density,as much as 2.59 flies/(cage·h).Among the cities,Chaoyang held the highest flies density as 20.85 flies/(cage·h),while Dandong held the lowest as 0.40 flies/(cage·h).The annual density dynamics of flies showed a unimodal curve with a peak in August,7.39 flies/(cage.h).Conclusion The density,population composition and seasonal fluctuation of flies in Liaoning Province in 2021 were preliminarily understood.Comprehensive control measures should be taken to reduce the density of flies.
