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 major species in Kashgar Oasis in Xinjiang and provide evidence for the prevention and control of visceral leishmaniasis in Kashgar Oasis. Methods In 2008 and 2011, in Kashgar oasis in Xinjiang, Pek’slam village, Hao Han township was collected by artificial hour and light-induced method during the daytime and nighttime. Based on the literature of the composition ratio of two species of white sand in the Kashgar Oasis in the past, the changes of the composition ratio of the main species in the Kashi Oasis were compared. Results A total of 1 453 white catfish were captured at night, of which 1066 were white wampee, accounting for 73.4% of the total; White-tailed Catfish were caught in the human chamber during the day, capturing a total of 387 catfish The main white-collar long tube, accounting for 87.5% (91/104), Wu white sandalwood only 12.5% (13/104). Compared with the previous survey results, the percentage of O. japonicus in the local population increased (69.3%), while the percentage of S. albiflori in the local population (30.7%) decreased. Conclusion In the village at night, the catfish catfish was mainly collected in white catfish and white catfish was mainly captured in white catfish during the day. Therefore, we should pay more attention to the role of S. alba in local spread of visceral leishmaniasis and develop corresponding control strategies.
