2009年西宁市城北区蝇类监测研究

Monitor result of fly at Chengbei district in Xi'ning city in 2009

目的掌握西宁市城北区的蝇类种群、密度和季节消长规律,有针对性采取蝇类控制措施。方法笼诱法。每个监测点设置1个配有新鲜饵料的天幕式捕蝇笼,放置8 h(9:00-17:00),收集到的蝇类用乙醚杀死后分类,统计各蝇种数量,并计算蝇类密度。结果西宁市城北区2009年平均蝇类密度为10.20只/笼;优势蝇种为厩腐蝇、舍蝇;蝇类季节消长呈单峰型,8月份达到最高峰。结论孳生环境和防治措施是影响蝇类密度和种群的主要因素。蝇类防治应采取环境治理为主、化学防治为辅的综合防治措施,以达到降低蝇密度,控制传染病发生与流行的目的 。

Objective To study the population density and seasonal fluctuation of fly at Chengbei district and take suitable measures for controlling fly.Methods Net attaching and setting up a cage with fresh bait in each monitoring point for 8 hours（9：00-17：00）,classifying the flies after collected and killed with aether,counting the number and calculating the density.Results The average fly ensity in Chengbei district in 2009 was 10.20 pieces per cage;the ascendent category were Muscina stabulans,Musca domestica vicina.The density and seasonal fluctuation of fly in Chengbei district showed single peak,and reached to top in August.Conclusion Propagate environment and control measures are the main factor to influence the fly density and population.The general control measures（environment harness mainly and chemic method as accessorial） should be taken to control fly,reduce the density and prevent the occurring of infectious disease and prevailing.
