内脏利什曼病是亚洲、非洲、南欧、中美洲和南美洲的热带和亚热带地区的人和狗的地方性原生动物疾病，其中白蛉（Phlebotomus和Lutzomyia属）作为媒介。在纽约一家猎狐犬养舍爆发的疫情和随后的监测显示，在美国的狗中广泛存在婴儿利什曼原虫感染，超出了已知的媒介沙蝇范围。在这项研究中，我们进行了监测白蛉在2001年和2002年夏天在两个领域：在纽约狗舍的理由，并在生态系统研究所（IES）10公里以外。使用CO2诱饵灯陷阱进行监测。以前在纽约不知道的Lutzomyia vexator种群在IES研究中心分布广泛，局部丰富（范围为0.26-1.16只苍蝇/诱捕器夜晚）。这些人群表现出双峰，仲夏活动高峰期，最丰富的成熟混合阔叶林内的陡坡。进一步的研究将是必要的，以确定是否纽约人口的L。狗舍附近的犬只可能与传播犬利什曼病有关。
Visceral leishmaniasis is an endemic protozoal disease of humans and dogs in tropical and subtropical regions in Asia, Africa, southern Europe, Central America, and South America, where sand flies (genera Phlebotomus and Lutzomyia) act as vectors. An outbreak in a New York foxhound kennel and subsequent surveillance revealed widespread Leishmania infantum infection of dogs in the United States, outside the known range of the vector sand flies. For this study, we conducted surveillance for sand flies during the summers of 2001 and 2002 at two areas: on the grounds of the New York kennel and at the Institute of Ecosystem Studies (IES) 10 km away. CO2-baited light traps were used for surveillance. Populations of Lutzomyia vexator, not previously known in New York, were widespread and locally abundant (range, 0.26-1.16 flies/trap night) at the IES site. These populations showed a bimodal, midsummer activity peak and were most abundant on steep slopes within mature mixed hardwood forests. Further research will be necessary to determine whether the New York populations of L. vexator in the vicinity of the kennel could be involved in transmission of canine leishmaniasis.
