Abstract
Phlebotomine sand flies occur throughout the tropics and subtropics, as well as in temperate regions of the world. They are vectors of human and canine leishmaniasis and sand fly fevers caused by phleboviruses. This study was aimed to determine the geographic and ecological characteristics of phlebotomine sand flies as vectors of leishmaniasis and to prepare a checklist of phlebotomine sand flies. The study was conducted in Qom province, central Iran, between April and November 2016. Qom is located in latitude 34.6399°N and longitude 50.8759°E with average annual minimum and maximum temperatures of 16.5 and 49°C, annual rainfall of 150mm and relative humidity of 84 and 28%, respectively. Sand flies were collected by sticky paper traps from Qom city and its six districts. The sand flies collected were separated from the sticky paper traps using an insulin syringe and kept in 70% ethanol for species identification using taxonomic keys. Also, a literature review was performed using all published reports on phlebotomine sand flies in this province during 1999-2015. A total of 28,410 sand flies from two genera and 14 species were collected. Phlebotomus papatasi, the main vector of zoonotic cutaneous leishmaniasis and arboviruses, and Phlebotomus sergenti, the vector of anthroponotic cutaneous leishmaniasis, were the predominant species followed by Phlebotomus kandelakii, P. major and P. alexandri. Fourteen species from two genera mostly from wet and mountainous areas were identified in the study area. Kahak and Markazi districts were identified as high-risk foci with numerous leishmaniasis vectors species; we recommend intensifying and strengthening of vector control programme in the area of study.
