为了解新疆伽师县内脏利什曼病流行区媒介白蛉的动态,于2016年6月15-30日白蛉季节高峰期间,以伽师县卧里托格拉克乡荒漠农业区为监测点,采用人房外墙捕蛉管人工捕集法、野外悬挂白布灯照诱引法和黏性油纸法捕集白蛉,观察白蛉密度、鉴定白蛉种类并观察雌蛉消化道自然感染利什曼原虫(Leishmania)前鞭毛体情况。结果共采集白蛉497只,经鉴定均为吴氏白蛉(Phlebotomus wui)。其中,雌蛉占75.3%(374/497),雄蛉占24.7%(123/497),雌雄比例3.04∶1。人房外墙捕集白蛉182只,密度为30.3只/人工小时;野外捕集白蛉259只,密度为43.2只/人工小时;居民庭院内捕集白蛉56只,密度为5.6只/张。剖检的109只吴氏白蛉雌蛉中,自然感染利什曼原虫前鞭毛体的2只,自然感染率为1.8%。提示卧里托格拉克乡白蛉密度甚高,存在利什曼原虫感染。
In order to understand the dynamics of white catfish in the predatory area of visceral leishmaniasis in Jiashi Prefecture, Xinjiang, during the peak season of white catfish on June 15-30, 2016, the monitoring area was located in the desert agricultural area of Toledula Township, Jiri County, Jiashi County , The use of artificial wall catching artificial catcher outside the wall, the lawn hanging white cloth lights according to induction method and sticky paper method to capture the whitefly, observe the whitefly density, identify the whitefly species and observe the female natural digestive tract infection Leishmania promastigotes. Results A total of 497 white catfish were collected and identified as Phlebotomus wui. Among them, 75.3% (374/497) of female fetuses, 24.7% (123/497) of male fetuses, and 3.04:1 were male and female. A total of 182 white catfish were collected from the external wall of the house, with a density of 30.3 / artificial hour. There were 259 white catfish collected in the field with a density of 43.2 / artificial hour. 56 white catfish were collected in the courtyard of residents, with a density of 5.6 / Zhang Of the 109 Wuqi white female rats in the autopsy, 2 were naturally infected with Leishmania promastigotes, with a natural infection rate of 1.8%. Tip Zhuo Tuogulake Township white clumps density is very high, there Leishmania infection.
