Abstract
ObjectiveTo investigate Phlebotomus sand fly fauna and their vectorial capacity in Hamadan, Iran. MethodsDuring the three consecutive years (2010-2012), from May to October, sandflies were sampled monthly from residential areas of Hamadan and selected villages using sticky traps. ResultsA total of 3 089 sandflies comprising 12 species from 2 genera were collected, of which 6 species are known vectors of leishmaniasis in Iran and/or other parts of the world. About 75% of the collected sandflies were of two dominant species, Phlebotomus kandelaki (38%) and Phlebotomus papatasi (36.6%). These species in combination with Phlebotomus major (6.8%), Phlebotomus sergenti (6.3%), Phlebotomus caucasicus (5.3%), Phlebotomus wenyoni (1.3%), Sergentomyia sintoni (2.9%) and Sergentomyia dentate (2%) collectively comprised the majority of the sandflies. Other species including Phlebotomus halpensis, Phlebotomus longiductus, Phlebotomus comatus and Phlebotomus alexandri each comprised only less than 1% of collected samples. ConclusionsAlthough none of the 158 dissected female Phlebotomus kandelaki and Phlebotomus papatasi were infected with leishmania promastigote, it is probable that in the future, factors such as environmental changes, migration and urbanization can ease the transmission of leishmaniases in this area.
