摘　　要：目的在新发现的流行区新疆塔里木盆地南缘民丰县调查内脏利什曼病(黑热病)的媒介蛉种。方法在民丰县安迪尔乡雅通古斯村居民点和附近野外采集白蛉,经鉴定后计算蛉种组成和数量比例;定人、定点、定时观察白蛉数量统计密度;观察白蛉昼夜活动的数量变动;解剖白蛉,分析雌蛉生殖营养周期;检查白蛉有无前鞭毛体自然感染。结果捕获白蛉1210只,其中99.17%(1200/1210)为吴氏白蛉;6月上中旬是该蛉季节消长的第一高峰;生殖营养周期分析表明吴氏白蛉为野生野栖蛉种,夜间活动的白蛉主要在户外吸血,有较强的亲人性;在2只白蛉体内查到自然感染前鞭毛体。结论塔里木盆地南缘民丰县安迪尔乡雅通古斯村存在内脏利什曼病传播媒介吴氏白蛉,并有利什曼前鞭毛体自然感染,表明当地存在内脏利什曼病自然疫源地。Objective To investigate the transmitting phlebotomine sandfly in Minfeng County, a newly-identified endemic area of visceral leishmaniasis in the south of Talim Pendi of Xinjiang. Methods Sandflies were collected using routine methods in and around the Yatonggusi village of Andier Township. The sandflles were identified to get their composition. Sandfly density was calculated following an observation at a given spot and time-period, and their appearance was recorded at night-time and day-tlme. Sandflies were dissected to analyze the gonotrophic cycle and to find infection of promastigotes. Results Phlebotomus wui was identified as the transmitting vector of visceral leishmaniasis in Andier Township, which occupied 99.2% of the sandflies collected. The first and second ten-day period of June was the first peak of its seasonal distribution. Analysis of the gonotrophic cycle revealed that Ph. wui was an exophilic species and appeared nocturnally for feeding with preference to human blood. Natural infection with promastigotes was found in 2 sandflies. Conclusion Phlebotomus wui is the transmitting vector for visceral leishmaniasis in the newly found endemic area of south Xinjiang.
