Abstract:

Objective To determine the species composition, ecological habits, and seasonality of flies in the urban area of Xi’an, China, and to provide a scientific basis for the prevention and control of flies and fly?borne diseases. Methods Cage traps with sugar and vinegar baits were used to capture flies. Monthly statistical analysis of surveillance data for the diversity of flies was performed from March to November each year. Results A total of 2378 adult flies were captured from 2009 to 2012 and classified into 15 species, 10 genera, and 3 families. The general average density was 2.65 flies/cage. The highest density was found in 2009 (3.00 flies/cage), and the lowest density in 2012 (2.47 flies/cage). Musca domestica (54.71%), Muscina stabulans (10.26%), Helicophagella melanura (10.13%), and Lucilia sericata (9.04%) were the predominant species. Conclusion The population density and seasonality of flies are related to the habitat, climate, and seasons. Integrated control measures with chemical and physical methods before activity climax will substantially reduce fly population density and the incidence of fly?borne diseases.
