The Study of Sand Fly Fauna in an Endemic Focus for Cutaneous Leishmaniasis in Fasa from April to October in the year 2013

Background & Objectives: Leishmaniasis as a zoonosis disease seen in three forms including Cutaneous, mucocutaneous, and visceral (kala- azar). The Leishmania transferred by sand flies is the causative agent of this disease. Considering that leishmaniasis is an endemic disease in Fasa, this study was performed to determine the sand fly species of Fasa, Materials & Methods: In this cross- sectional study from April to September 2014, the fauna of sand flies was investigated. Sampling was done in villages with above, medium, and low incidence by using sticky traps every 15 days. Then, captured specimens were mounted and identified by specific key. Results: 3842 sand flies were captured for ecological studies. 2305 of them (60%) were males and the rest of them were females. 1152 specimens (30% of them) were from indoors and the rest were from outdoors. Totally, 10 species were identified including Phlebotomus. Papatasi, Ph. Alexandri, Ph. Sergenti, Ph. Mongolensis, Ph. Bergeroti, Ph. Caucasicus, Sergentomyia theodori, S. Baghdadis, S. sintuni, and S. antennata. Among captured specimens Phlebotomus Papatasi, Ph. Sergenti had the first and the second places, respectively. Conclusion: Sandflies in Fasa are very active with high prevalence and species diversity. Phlebotomus Papatasi as the predominant species transfers Leishmania from rodents to humans. This subject is related to the prevalence of rural leishmaniasis in this area. According to the semi-domestic vector, spraying is not helpful in a rural foci of cutaneous leishmaniasis. But the control of reservoir and educating the residents about prevention ways of bite are effective in disease control and prevention.
