Diversity and Dynamics of Sand Flies (Diptera: Psychodidae) of Two Cutaneous Leishmaniasis Foci in the Fes-Boulemane Region of Northern Morocco

Cutaneous leishmaniasis (CL) is an infectious disease caused by various species ofLeishmaniaand transmitted by several species of sand flies (Diptera: Psychodidae). In order to evaluate the risk of leishmaniasis transmission in Fes-Boulemane, an investigation was carried out in two localities, Aichoun and Bouasseme, during 2011. From January to December, 1120 specimens were collected in Aichoun comprising six species belonging to two genera:Phlebotomus sergenti(76.07%),Phlebotomus longicuspis(9.01%),Phlebotomus perniciosus(8.48%),Phlebotomus papatasi(4.82%),Sergentomyia minuta,andSergentomyia fallax. For Bouasseme, seven species were identified withPhlebotomus sergenti(60.39%) dominating, followed byPhlebotomus perniciosus(20%) andPhlebotomus longicuspis(12.15%). The remaining species,Phlebotomus papatasi,Phlebotomus ariasi,Sergentomyia minuta,andSergentomyia fallax,were less prevalent. The activity of sand flies in both localities is marked by the dominance ofPh. sergentiwith two peaks occurring in June and September. In order to obtain a better understanding of sand fly diversity among their species, results were analyzed by the ecological indices determinant: specific richness, the relative abundance, and Shannon-Weiner index (H′). Further studies of sand fly diversity should employ statistical tests and molecular analyses. This study can be useful in the implementation of appropriate future control measures.
