 Background and Aim: Sand flies are responsible for transmission of leishmaniasis, papatasi fever and carrion disease. Warning of sand fly population is the first step for the establishment of baseline data for the vector control operations of visceral leishmaniasis (VL). In order to attempt to the difference between species composition and bieocology of sand flies, the comparative research was carried out in west and east of Meshkinshahr district where having high and low prevalence of VL as well as mild semiarid and semiarid steppe climates respectively.

 Materials and Methods : Sand flies were biweekly collected using sticky paper traps from indoor and outdoor shelters from four villages at west and east of Meshkinshahr district. The specimens was removed from sticky paper traps and washed in acetone and preserved in 70% alcohol. The preserved sand flies were mounted using Puri’s media and identified using valid keys. The labeled specimens were deposited in Medical Entomology Museum, School of Public Health under code GC22ST6-93 .

 Results: During this study, totally 783 and 400 sand flies were respectively caught from indoor (19-27%) and outdoor (73-81%) of both at west and east. The sex ratios of collected sand flies were estimated 2.3 and 1.9. in latter areas. The genera percentage of sand flies were 66.3-64.5% for Phlebotomus and 33.7-35.5% for Sergentomyia compromising of 7 subgenera which included in 20 and 17 species respectively in west and east areas. For the first time, Se.sintoni and Se.mervynae was reported in Meshkinshahr district.

 Conclusion: The Ph.kandelakii and Ph.perfiliewi were introduced as prevalent species in the west area compared to the east. In the west area, activity duration and number of generation was higher than east. The prevalent species in the east area was Ph.papatasi. The high density of Ph.anderjevi was seen in both studied areas. The most proven vectors of visceral leishmaniasis were revealed in the west of Meshkinshahr district.
