First Report on Sergentomyia sintoni and Sergentomyia clydei (Diptera: Psychodidae): Their Natural Promastigote Infection and Some Aspects of Biology in Sistan-Baluchistan Province, Southeastern Iran

ObjectiveTo This paper has explained initial survey on two vectors of lizard leishmania promastigote in south-east of Iran.MethodsTotally 333 S. sintoni and 475 S. clydei were collected from rodent burrows by sticky traps in three villages of Chabahar County. Sand flies were dissected in a drop of normal saline.ResultsNatural leptomonad infection rate involved %2.1 S. sintoni and %5 S. clydei. The finding about seasonal variation was showed the highest infection rate in two vectors in the first week of August. The highest population of gravid and semi-gravid of main vectors of Lizard leishmaniasis, S. sintoni and S. clydei, were observed in the last week of September and the lowest were in the last week of July. The examination of accessory glands showed that the maximum population of parous was observed in the last week of September and the last week of July it was at least. This is the first report of leptomonad (promastigote) infection in S. sintoni and S. clydei in Sistan-Baluchistan Province, southeastern Iran.ConclusionsA further study with more focus on biology of Sergentomyia genus is suggested.
