Objective To understand the flies species, density and seasonal variation in the past five years in Haidian District, Beijing, and to provide a scientific basis for the comprehensive control of flies. Methods Cage induction method. Results A total of 21 657 flies were collected from 2011 to 2015 with an average flies density of 12.13 per cage. Among them, the highest density was in 2012, the annual average density reached 18.88 per cage, and the lowest density in 2013 was only 6.43 per cage . Sesamia fuscus and Lucilia sericata were the dominant species, accounting for 42.02% and 31.93% respectively. The density of greenbelt in the park was the highest with an average of 20.94 / cage.
