Lutzomyia evansi, an alternate vector of Leishmania chagasi in a Colombian focus of visceral leishmaniasis

Transmission, reservoir hosts and control of zoonotic visceral leishmaniasis

“…At least a dozen sandfly species of the subgenus Larroussius have been incriminated as vectors of L. infantum in the Old World, including Phlebotomus perniciosus, P. ariasi, P. perfiliewi, P. neglectus and P. tobbi in Europe (Killick-Kendrick, 1999). In Latin America, the most important vector is the Lutzomyia longipalpis species complex, with L. evansi suspected to be the important vector in some foci in Colombia and Venezuela (Travi et al 1990 ;Montoya-Lerma et al 2003), and L. cruzi incriminated in parts of Brazil (dos Santos et al 1998).…”

Lutzomyia longipalpis and the eco-epidemiology of American visceral leishmaniasis, with particular reference to Brazil: a review

“…longipalpis was seemingly absent. A further 26 years were to elapse, however, before this suspicion was substantiated, when Travi et al (1990) showed that 87% of the sandflies captured in a focus of AVL in the Córdoba Department of Colombia were Lu. evansi and that one of these flies was infected with L. i. chagasi, as identified by isolation of the parasite and its characterization by isoenzyme electrophoresis.…”

“…It is quite possible that other sand flies, besides the classical ones, could be vectors in certain situations. Thus in Colombia it has been shown (Travi et al 1990) that Lu. evansi is an important VL vector in the absence of Lu.…”
