During growing seasons of years 2006 & 2007, a faunistic survey on Syrphidae family(Diptera) in agroecosystems of Neyshabor region, Khorasan-e-razavi province was carried out. In this study, 3 collection methods: Yellow water trap, Malaise trap and Sweeping net were applied. The results showed a large difference between different collection methods. Specimens of 14 species collected by Malaise trap while Yellow water trap collected 5 species and 8 species exclusively collected by sweeping net. In total, 22 species belonging to 14 genera have been identified. All species are reported from the region for the first time. Among these, E.tricolor & H.trivittatus are new for Khorasan-e Razavi province fauna. Recording the species, E.jacobsonii from Neyshbor, the distribution range of this Syrphid which was restricted to south east Iran is extended. Shannon-Weiner index of biodiversity measured for Malaise trap was higher than that calculated for yellow water trap.
