Özet
The natural enemies of Russian wheat aphid [Diuraphis noxia (Kurdjumov)] are well documented in South Africa (Aalbersberg et al. 1988), in USSR (Kovalev et al. 1991), in Eurasia (Gruber et al. 1991), in California (Bernal et al. 1993), in Morocco, Jordan, Syria (Miller et al. 1992), and in Turkey (Miller et al. 1992, Elmali 1996). Although Anthicidae is commonly referred to as a family containing predator species (McQuillan et al. 1982, Smith et al. 1987, Frank and Slosser 1991, Elmali 1996), Anthicus unicolor Schm. has not been previously reported in the literature as a predator of D. noxia. This anthicid was also a first record for Turkish fauna. It was locally seen in only one field infested with D. noxia at high density in Konya province. However, after A. unicolor adults suddenly appeared in large numbers, D. noxia declined rapidly. A. unicolor has a large brown egg which it deposits at the top of a short white fiber like a neuropteran egg. Eggs were where D. noxia colonies were present. A. unicolor was able to prey on D. noxia in rolled leaves and other concealed places. Although Sitobion avenae (F.), Rhopalosiphum maidis Fitch, R. padi (L.) (Homoptera: Aphididae), and Sipha (Rungsia) elegans Del Guercio (Homoptera: Chaitophoridae) were also prey of A. unicolor, D. noxia was preferred.
