[Sandflies Fauna of the Focus of Keur Moussa: Current Data on Diversity and Seasonal Variations (Thies, Senegal)]. Bull Soc Pathol Exot. 2018;111(1):38-45 Authors: Omar SAS, Serigne M, Niang AA Abstract An inter-epidemic oversight was conducted in the cutaneous leishmaniasis focus of Keur Moussa (Thies region) between June 2015 and October 2016, more than 20 years after the last epidemic. The three sampling methods (adhesive traps, CDC light traps, and indoor pyrethroids sprays) allowed the capture of 1,746 sand flies belonging to 2 genera and 24 species, those involved in the transmission of leishmaniasis in Senegal, as well as 11 new species for the focus. The vector of human cutaneous leishmaniasis in Senegal, Phlebotomus duboscqi Neveu-Lemaire, 1906, represents 10.9% of this fauna. Sergentomyia schwetzi, one of the species involved, with Sergentomyia dubia and Sergentomyia magna, in the transmission of canine leishmaniasis in Senegal, is the most abundant species with 38.1% of the samples. The other two species have individually smaller percentages. Seasonal variations of the abundance show an intense activity of sandflies at the end of the dry season under the influence of high average temperatures and a humidity exceeding 50%. Rains are a limiting factor. According to the enrichment of the fauna and the high density of the different vectors of leishmaniasis in this focus, particularly P. duboscqi, a specific importance should b...
