Incrimination of Lutzomyia cruzi as a vector of American Visceral Leishmaniasis

Phlebotomines (Diptera: Psychodidae) in forested areas of the Serra da Bodoquena, state of Mato Grosso do Sul, Brazil

“…almerioi, just as on humans, predominated absolutely in the captures with Shannon traps. Its infection rate among the females captured on humans (0.13%) and in the Shannon traps (0.22%), both on the Pitangueiras farm, was close to that observed in some foci of cutaneous leishmaniasis (Pessôa & Coutinho 1941, Hashiguchi et al 1992, Galati et al 1996, Luz et al 2000, but lower than that for visceral leishmaniasis (Santos et al 1998).…”

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

“…To add to the confusion, a distribution overlap makes it difficult to incriminate either species as the vector of AVL in areas where the two are found together. Santos et al (1998) dissected a large number of sandflies captured in CDC light-traps around houses in a focus of AVL in Corumbá and Ladário, Mato Grosso do Sul, and found promastigotes in 14 female specimens, all with the morphology of Lu. longipalpis/Lu.…”

The presence of Lutzomyia longipalpis in a focus of American visceral leishmaniasis where the only proven vector is Lutzomyia cruzi. Corumbá, Mato Grosso do Sul State

“…These collections resulted in the incrimination of Lutzomyia cruzi as the vector of AVL in the absence of Lu longipalpis in Corumbá 4 .…”
