Studies on sandfly fauna (Diptera: Psychodidae) in a foci of cutaneous leishmaniasis in mesquita, Rio de Janeiro State, Brazil.

In a study on vectors of cutaneous leishmaniasis in Mesquita, Rio de Janeiro State, Brazil, eleven species of sandflies were found: Lutzomyia longipalpis, L. fischeri, L. quinquefer, L. intermedia, L. whitmani, L. shannoni, L. cortelezzii, L. edwardsi, L. migonei, L. lanei and L. firmatoi. Lutzomyia intermedia was the predominant species. It was collected indoors but in much higher numbers outdoors, in the close vicinity of houses. In comparative captures it was found to feed more frequently on equines, and less frequently on man and dogs. Studies, using man and animals as baits, showed that blood-feeding started in the evening, and remained stable during the night, until early morning. June, August and October were the months of highest density.
