利什曼原虫物种和它们的载体之间或多或少有密切的配合，一种寄生虫的已证实载体通常无法支持另一种寄生虫的充分发育。这种契合可能是媒介和寄生虫共同进化的结果，值得注意的是，如果一种利什曼原虫在其分布区的不同部分有不同的无脊椎动物宿主，那么这些媒介通常是密切相关的。这种限制的流行病学后果是，第一，旧大陆皮肤利什曼病的传播，以及在较小程度上内脏利什曼病的传播，受到适当媒介分布的限制;第二，次级媒介对利什曼病流行病学的重要性不如疟疾。
There is a more or less close fit between Leishmania species and their vectors with the proven vector of one parasite often unable to support the full development of another. This fit is presumably a result of coevolution of vector and parasite and it is notable that, if a Leishmania has different invertebrate hosts in different parts of its range, the vectors are often closely related. The epidemiological consequences of this restriction are, firstly, that the spread of the cutaneous leishmaniases of the Old World and, to a lesser degree, that of visceral leishmaniasis is restricted by the distribution of suitable vectors and, secondly, that secondary vectors are of less importance on the epidemiology of the leishmaniases than they are in malaria.
