A search for Russian wheat Aphid (RWA), Diuraphis noxia (Mordvilko) and its natural enemies was conducted from 1990-1992 in 7 provinces of Iran. Of the 326 locations surveyed RWA was found at 179 and parasitized aphids at 114. The RWA is not a serious economic pest in any of these 7 provinces. High levels of the aphid were encountered only in localized of small areas of fields in all provinces. This survey revealed the presence of 5 species of parasitoids and 2 species of predators of Russian wheat aphid in Iran. The most abundant and widely distributed parasitoids were Diaeretiella rapae and Aphelinus albipodus varipes. They were found in more varied climatic areas than any of the other species. Aphelinus albipodus varipes was more widely distributed than D. rapae. Aphidius uzbekistanicus and A. matricaria were found with less abundance, and Praon volucre was tha rarest species found in this exploration. Eupeodes nuba and Leucopis ninae, and coccinelid predators were widely distributed and not generally found within the rolled leaves
