The object of this study was to determine the genetic structures of three vector species, Phlebotomus tobbi, Phlebotomus papatasi, and Phlebotomus sergenti, in the Cukurova Region of Turkey, an endemic focus of cutaneous leishmaniasis. The genetic diversity indices, neutrality tests and hierarchical analysis of molecular variance (AMOVA) were performed using partial sequences of ITS2 and cytochrome b gene regions. In all species, within population genetic variation was higher than between population variation for ITS2 gene region. Fst values were low and non-significant for P. sergenti, and were higher for P. papatasi and P. tobbi indicating a weak structuring between populations. AMOVA tests suggest any substantial isolation between populations within species. AMOVA analysis of cyt b gene region revealed significant genetic structuring between populations for P. papatasi and P. sergenti. Fst values were relatively high and significant for these species indicating a certain degree of isolation between populations. However, in P. tobbi, any significant population genetic structuring was detected. Tajima's D and Fu's Fs values were negative and significant in all three species might be indicating a demographic expansion.
