Abstract The Syrphidae family with almost 6000 described species, 15 Tribes and 3 subfamilies is one of the largest families of Diptera. They known as hoverflies or flowerflies. The larvae of subfamily Syrphinae are considered the specialized aphidophagous predators play an important role in the reduction of aphid populations in agroecosystems. Almost all the adult syrphids feed on pollen or nectar and they are crucial agent inpollinating process. A survey was conducted to identify the hoverflies in Roshtkhar city (Razavi Khorasan Province) during 2010-2011 led to collected 340 specimens. Sampeling was done in 4 period from 2 station. Among of all specimens, 26 species belonging to 12 genera and 2 subfamilies (Syrphinae and Eristalinae) were verified. Their larvaes feeds contain: 18 predatory species, 5 saprophages species and 3 phytophagus species were identified. That all of them were newly recorded for the Roshtkhar region. That all of them were newly recorded for the Roshtkhar region.

Abstract The Syrphidae family (Known as hover flies or flower flies) is one of the largest families of Diptera with almost 6000 species. Adult flies feed on nectar and pollen of flowers and they are crucial agent in pollinating process. The larvae of many species of Syrphidae are predators of Aphids and play an important role in biological control of pests. In the following faunestic investigation, some ecological indices of Syrphidae family was carried out in Torbat-e Heydarie, Roshtkhar & Khaf cities (Razavi Khorasan Province) during 2010-2011and the most dominant species has been identified in each station of the study area. Adult species were collected randomly with entomological net and transferred to animal biosystematics lab in Shahid Beheshti University. The specimens have been identified by valid identification keys. After identification of species in 987 specimens, they have been sent to prof. Barkalov from institute of animal systematics and ecology, Siberian, Russia to confirm the obtain results and specimens were stored in the insect museum of bioscience faculty of Shahid Beheshti University. After survey of Iranian Syrphidae checklist, three species; Eumerus ornatus, Pipizella virens, Platycheirus fulviventris are new recorded from Razavi Khorasan Province. Two genus Pipizella and Platycheirus, are added to genus reported of Razavi Province’s fauna. So far, the report of Platycheirus fulviventris from Guilan Province, Pipizella virens from north of Iran and Eumerus ornatus from Damavand city show that wider the range extension of this species in Iran.
