Human indigenous cutaneous leishmaniasis caused by Leishmania donovani complex is endemic in Sri Lanka. We performed an entomological survey to determine the distribution of probable vector species. Sand flies were collected in districts in the dry zone, in the wet zone highlands, and in the wet zone coastal belt of Sri Lanka using CDC light traps, sticky traps and cattle-baited net traps during July, 2005. The survey was reconducted in February, 2006. Overall, 584 sand flies belonging to Phlebotomus (266 specimens, 2 species) and Sergentomyia (318 specimens, 8 species) genera were collected. A total of 266 Phlebotomus was identified as P. argentipes (258/266; 97%) and P. stantoni (8/266; 3%) . The identification studies of Sergentomyia specimens showed that there are at least 8 species in Sri Lanka. Higher number of Phlebotomus sand flies (76/266) were caught in the southern part of the country compared to the other parts probably due to different ecological aspects. P. argentipes were widely distributed throughout the island whereas P. stantoni were collected only in four districts. Since P. argentipes is known to be the vector of L. donovani responsible of visceral leishmaniasis in India, this species may be incriminated as the most possible vector of human cutaneous leishmaniasis in Sri Lanka.
由杜氏利什曼原虫复合体引起的人类本土皮肤利什曼病在斯里兰卡呈地方性流行。我们开展了一项昆虫学调查,以确定可能的病媒种类分布情况。2005年7月,在斯里兰卡的干旱地区、湿润地区高地以及湿润地区沿海地带,使用疾控中心灯光诱捕器、粘性诱捕器和牛诱饵网捕器收集了白蛉。2006年2月再次进行了该调查。总体而言,共收集到584只属于白蛉属(266只标本,2个物种)和司蛉属(318只标本,8个物种)的白蛉。总共266只白蛉被鉴定为银足白蛉(258/266;97%)和斯坦顿白蛉(8/266;3%)。对司蛉标本的鉴定研究表明,斯里兰卡至少有8个物种。与该国其他地区相比,在该国南部捕获的白蛉属白蛉数量更多(76/266),这可能是由于不同的生态因素。银足白蛉在全岛广泛分布,而斯坦顿白蛉仅在四个地区被收集到。由于已知银足白蛉是印度内脏利什曼病病原体杜氏利什曼原虫的病媒,该物种可能是斯里兰卡人类皮肤利什曼病最有可能的病媒。
