Distribution and diversity study and distribution of the snail killing flies (DIPTERA:SCIOMYZIDEA ) in noor city, central part of mazandaran province

The family Sciomyzidae belongs to the order Diptera. The larvae of snail-killing flies feed on aquatic snails. These snails host a large group of human and animal parasites such as Fasciola and Schistosoma. Fighting these parasites takes place through different methods such health trainings, environmental rehabilitation, treatment of patients, and fighting the intermediary host snails. Hence, these flies play an important role in biological controls. In this study, the use of molluscicide flies in Nour County in Mazandaran Province was studied from April to August 2015 and a total of 1269 mature samples were obtained from the following five stations using sweeping nets: Izad Shahr paddy field, Tirakdeh village paddy field, Chamestan, Sabezeh Rud (Royan), and Nour. The samples were transferred to the University’s systematic animal studies laboratory following stabilization. Finally, after investigations and identity examinations it was found that the samples of the subfamily Phaeomyiinae had the one genus and one species. It was found that the subfamily Sciomyzinae consists of the following two tribe: Sciomyzini and Tetanocerini. The tribe (Sciomyzini) consists of three genera and five species whereas the latter one (Tetanocerini) consists of two genera and two species. Therefore, both of the subfamily have a total of six genera and eight species that the most abundant species are Pelidnoptera leptiformis and the least abundant species are belonging to Colobaea punctata ; and from the point of location , the most abundancy had been occurred in Sabze-rud royan and the least abundancy had been occurred in Tirakde village.
