摘　　要：目的 调查研究新疆喀什绿洲主要蛉种的组成比,为制定喀什绿洲内脏利什曼病防制策略提供依据. 方法 2008、2011年在新疆喀什绿洲伯什克拉姆乡、浩罕乡于白天和夜间以人工小时法、灯诱法采集白蛉,解剖鉴定蛉种,计算当地长管白蛉和吴氏白蛉的种群组成比,结合以往新疆喀什绿洲内2种白蛉的组成比的文献,比较喀什绿洲主要蛉种组成比的变化. 结果 夜间共捕获白蛉1 453只,其中吴氏白蛉1 066只,占73.4％;长管白蛉387只,占26.6％;白天在人房内捕捉白蛉,共捕获白蛉104只,以长管白蛉为主,占87.5％ （91/104）,吴氏白蛉仅占12.5％ （13/104）.与以往调查结果相比,吴氏白蛉占当地蛉种组成比（69.3％）上升,长管白蛉占当地蛉种构成比（30.7％）下降. 结论 夜间村内捕获白蛉以吴氏白蛉为主,白天人房内捕获白蛉以长管白蛉为主.吴氏白蛉占当地蛉种组成比（69.3％）上升,因此应重视吴氏白蛉在当地内脏利什曼病传播中的作用,并制定相应的防治策略.Objective To investigate the composition ratio of main sandfly species and to provide evidence for generating prevention and control strategies against visceral leishmaniasis in Kaxgar oasis.Methods The investigation was done at the settlements of Baishikeranmu township and Haohan township of Kaxgar oasis in 2008 and 2011 by exploring labor-hour method and the light trap method in day-time and at night.Sandfly species composition ratio was calculated after sample anatomy and species identification,then was compared,the variation of species composition ratio in terms of Phlebotomus longiductus and Phlebotomus wui according to literature information about sandfly composition in Kaxgar oasis.Results A total of 1 453 sandfly were captured at night,including 1 066 Phlebotomus wui and 387 Phlebotomus longiductus,accounting for 73.4% and 26.6% respectively.A total of 104 sandfly were captured in the room during the daytime,including 91 Phlebotomuslongiductus and 13 Phlebotomus wui,accounting for 87.5% and 12.5% respectively.Compared with the previous survey results,the species composition ratio（69.3%） of Phlebotomus wui rose.On the contrary,the species composition ratio （30.7%） of Phlebotomus longiductus declined.Conclusion Phlebotomus wui was the main sandfly species in the villages at night.Phlebotomus longiductus was the main sandfly species in the room in daytime.The species composition ratio（69.3%） of Phlebotomus wui rose significantly.Thus we need pay attention to the role that Phlebotomus wui plays on the visceral leishmaniasis transmission,and formulate corresponding countermeasures against visceral leishmaniasis.
