Eleven phlebotomine sand flies species were captured in the Ferlo sahelian region during monthly surveys from April 1 992 to June 1993. Around the Niakha ground pool, the most well studied location, the most abundant species were respectively: Sergentomyia dubia (40,71%), S. schewtzi (25,54%) and S. clydei (13,84%). In total, 98,73% of the specimens captured belonged to the genus Sergentomyia, and only 1,27% to the genus Phlebotomus. The sand flies community showed a peak of abundance in January. The sand flies preferred habitats were termite hills, followed by animals burrows and tree holes. In the five communities studied, the most abundant species was S. dubia, the gecko leishmaniasis vector. P. duboscqi, the human cutaneous leishmaniasis vector, was captured each month, despite its low abundance, except in the ratel burrows. Chandipura and Saboya viruses, as well as two probably new viruses, were isolated from sand flies.
