Objective To survey the distribution,species composition and seasonal fluctuation of flies at five types of habitat in Zhongshan,compare the trapping efficiency of two kinds of bait for diverse fly species,and to provide scientific data for the prevention and control of flies. Methods The density surveillance of flies was conducted by using trap cages twice per month from October 2017 to October 2018,surveillance site covered 5 different habitat types,including the park,the periphery of the restaurant,the residential area,the hospital and market. Cages were placed between 9:00 to 10:00 and collected between 16:00 to 17:00,and the total period of surveillance was about 6 hours per day. Two trap cages were placed side by side at each monitoring point,using fish viscera and fruit bait for trapping respectively. The captured flies were brought back to laborotary for statistics and classification. Results A total of 6 128 flies were captured,classified into 39 species belonging to 23 genera of 5 families,the dominant fly species was Chrysomya megacephala,followed by Achoetandrus rufifacies and Hemipyrellia ligurriens,respectively accounted for 51.30%,20.00% and 9.92%. In the five types of habitat,the highest population diversity appeared in the park and the lowest in the market. The seasonal fluctuation of the density of flies showed a three-peak curve,the highest peak,the second peak and the smallest peak appeared in late May,early March and early September respectively. The number and species of flies in fish viscera bait were all more than that in the fruit bait.Conclusion The dominant species of flies in Zhongshan were C.megacephala,A.rufifacies and H.ligurriens. The park was important area that should be surveilled. The trapping effect of fish viscera was obviously better than that of fruit,and it is a suitable bait for routine monitoring of flies.
