Abstract
A faunistic list of Syrphidae sampled in the agroecosystems of Neyshabur (Khorasan-Razavi Province) through Malaise, yellow water traps and hand net is hereby presented for the first time. A total of 22 species were collected, including 13 species through Malaise trap, 5 through yellow water trap as well as representatives of all species sampled through hand net. Among the species collected, 8 including phytophagous ones were exclusively sampled through hand net. In the case of Malaise trap the hover fly population was strongly dominated (73%) by 3 common species of: Sphaerophoria scripta, Episyrphus balteatus, and Eupeodes corollae while, in the yellow water trap, Episyrphus balteatus was the key species representing about 45% of all specimens. Shannon-Weiner index of biodiversity found out for Malaise trap (H= 1.86) was higher than that calculated for yellow water trap (H= 1.39). The relative efficiency of the three collection methods is discussed.
