摘要:

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。

Abstract:

To understand the changes of sand flies in endemic regions of visceral leishmaniasis in Xinjiang, sand flies were captured using arrest tubes on outer walls of human houses, light traps in field, and viscous oil-papers, in the sampling site of Gholtoghrak desert agricultural area in Jiashi County from June 15 to June 30, 2016. The density and species of sand flies were determined and identified, respectively. The infection status with leishmania promastigote in the digestive tract of female sand flies under natural conditions was examined. Totally 497 sand flies were collected, all identified to be Phlebotomus wui with a female-to-male ratio of 3.04 ∶ 1 (374 versus 123). A total of 182 sand flies were captured using arrest tubes, with a density of 30.3/work hour; 259 sand flies were captured using light traps in field, with a density of 43.2/work hour; and 56 using viscous oil-papers in courtyards, with a density of 5.6/piece. One hundred and nine female sand flies were dissected, and two showed infection with leishmania promastigote in the digestive tract, resulting in an infection rate of 1.83%. These findings suggest a high density of sand flies and the presence of Leishmania infection in Gholtoghrak area.
