Abstract: Before administrating the integrated programme for controlling flies, the density of fly in Chifeng was very high. There were 44 species of flies identified in the local area, among which Muscidae (M) domestica, M.stabulans (Fall), Fannia eanicularis (L), phormiinae regina(Mg) and Lucia sericata (Mg) were the dominant species.After three consecutive years (from 1987 to 1989), having taken effort to carry out the integrated programme against flies. The programme consists of comprehensive improvement of the environmental sanitation, together with chemical managment and physical measures against flies.About a hundred public lavatories and 6 339 residential toilets were repaired and rebuilt and setting up 22 refuse bins and garbage dumps spots for daily clearing refuse every day throwing out. Setting up cleaner-battalion consisting of 510 individuals, tacter or lorries for transportting refuse. Some special enterprises, such as food products, wine brewaies and Butcheries were instructed to be reformed or rebuilt in respect of their sanitory facilities, enhancing their antiflies equipments, as well as establishing hygienic regime for foods productions and appropriate treatment of leftover bits of pieces in proper spots. All above mentioned measures were able to control effectively the multipliation of flies.Successful application of Furadan Bait plate and using spray with insecticides such as Deltamethrin at a concentration of 20mg/m², and with Cypermethrin at a concentration of 40 mg/m² were used in door, and it was found that these treatments were sufficient to control the breeding of flins.The Health inspections were conducted by specialists from the Council of Chinese Central Patriotic health movements, the results showed that by checking different varieties of 1213 rooms the rate of density of flies was found to be 1.65% (flies were found in 20 rooms) and among 348 different kind of breeding sites checked, 3 positive sites were recovered, consequently, the breeding rate of flies was much reduced to 0.86%. The experiences regarding of the measure and managements achieved in Chifeng, appear to be very useful for popularization as they are economic and suitable for the basic units, we believe that these measure could also be apply to any medium sized town in future whenever is in need.
