Abstract

In this survey, species diversity of sawflies (Hymenoptera: Symphyta) in north forests Iran was studied. Eight Malaise traps were installed in Mazandaran and Golestan at different forest sites from March to November of the year 2016. Sampling procedures were similar at different locations. The collected specimens were identified to species level and the number of each species was counted. Totally, 37 species were collected and identified. The species diversity were calculated by software SDR4. Results showed based on indices of evenness, richness and diversity that Shamooshak forest in Golestan and Haftkhal forest in Mazandaran with 18 and 14 species respectively had the highest diversity. Moreover, diversity and evenness in Golestan was more comparing to than Mazandaran province. Among all species, Tenthredopsis ornata with 127 specimens (37.79%), Cladius pectinicornis with 58 specimens (17.26%), and Allantus didymus with 34 specimens (10.12%) had the most abundance respectively.
