Abstract:

Objective To get an insight into the density and seasonal fluctuation of flies in the urban area of Tai’an city, providing a scientific basis for the development of fly control programs. Methods Three farmers’markets six restaurant-surrounding areas, three city green belts and three residential areas were randomized as the fixed monitoring sites and the cage alluring was conducted to monitor the density of flies. Results A total of 7088 flies were captured from 2007 to 2010 with an average fly density of 14.8/cage, of which the dominant species were Musca domestica (19.6%), Muscina stabulans (19.6%) and Lucilia sericata (17.1%). The habitats that were listed in terms of the fly density in a descending order were farmers’markets, green belt, dining environment and residential community. The interannual and interhabitat fluctuations of fly density followed a single-peaked curve, which appeared in July and August. Conclusion The density of fly population in the urban area of Tai’an city peaks in July and August, and it is suggested that integrated measures be taken to concentrate on the control and prevention of flies in the period of time to reduce the density of flies and the prevalence of communicable diseases spread by flies.
