Abstract：Objective To study the density and species composition of flies in Longchang from 2020 to 2024,so as to provide a reference for scientific control.Methods From 2020 to 2024,the surveillance of flies was carried out in the farmers'market,catering surroundings,green belts and residential areas in Longchang by using cage trapping method.One-way analysis of variance was used to compare differences between groups.Results From 2020 to 2024,a total of 1 301 flies were captured in Longchang,and identified as belonging to 12 species,10 genera and 4 families.The domain fly species were Muscina stabulans(accounting for 42.30%),Musca domestica(accounting for 16.10%),Boettcherisca peregrina(accounting for 12.50%),and Lucilia sericata(accounting for 11.00%).The average annual density of flies was 5.91 flies/cage.Higher fly densities were occurred annually in May,peaking at 36.60 flies/cage in May 2022.Fly density was relatively lower in the second half of the year.The species composition and densities varied among different habitats.Conclusions The fly density in Longchang is relatively high in May.Flies should be controlled based on the trend of fly density and the breeding conditions of different habitats,combined with physical and chemical measures,including strengthening environmental management improvement,promoting fly prevention facilities,such as fly killing lamps and fly sticks.
