Abstract

Studies carried out on night activity of sandflies in an endemic area of leishmaniasis have shown the night cycle of the most abundant species: Phlebotomus perniciosus Newstead, 1911 and Phlebotomus sergenti Parrot, 1917. This cyle is directly related to environmental conditions and physiological stage of females. So, warm and dry conditons allow sandflies activity is continued all night long. With lower temperatures and higher relative humidity values sandflies go out from their resting sites in waves. The higher densities, measured in sandflies per hour, have been reached from 21 to 24 p.m.; so, this is the most important epidemiological risk period for dispersion of leishmaniasis, because 95 per cent of females have not fed yet and, accordingly, they should be more active to find a host.
