Abstract: Two methods of monitoring flies population density were carried out in Shanghai.The results showed that Chrysomya megacephata (34%),Lucilia sericata (34%) and Aldrichina grahami (9%) were attracted to a mixture of putrid fish and soybean sauce, and Musca domestica (41%),C. megacephata (23%) and L. sericata(13%) were attracted to a measure that compounded by a mixture of brown sugar and vinegar ,and a commercial sticky card. The flies population density of two methods varied with the seasons, and had similar chart. The flies population density of two methods had positive correlation, and the density of most of these years also has linear regression with temperature. The attraction of brown sugar and vinegar was more unvaried than that of putrid fish and soybean, so the combine measure is worthy to be recommended for monitoring flies population density , and can reflect the main specimens of flies of city and their changes with the seasons.
