“…A significant difference was found for the parasitoid complex of Sitobion avenae, based on all the data. According to our results, A. ervi is a rare parasitoid of cereal aphids in Iran, contrary to its high abundance in Europe and North America (Starý, 1976b;Powell, 1982;Pike et al, 1997;Al-Dobai et al, 1999;Sigsgaard, 2002). S. graminum, which is the most widely distributed, was parasitized by the greatest diversity of parasitoids.…”

Abstract. Eleven species of parasitoids were found to attack 7 species of wheat aphids in Iran. The Simpson's Index of diversity (D) used to compare the aphidiine diversity in various cereal crop systems in geographically different regions of Iran ranged from 0.197 to 0.488, depending on locality. There were significant differences among species diversities at different altitudes. The central highlands (1000-1500 meters above mean sea level) were the areas with the most diverse aphid parasitoid complex, differing significantly from that at lower and higher altitudes. We found that altitude explained about 10% of the cereal aphid parasitoid distribution pattern in Iran. Species of the genus Aphidius Nees were the most abundant and widely distributed. These were Aphidius rhopalosiphi De Stefani, Aphidius uzbekistanicus Luzhetski, Aphidius colemani Viereck and Aphidius matricariae Haliday. A. uzbekistanicus, Ephedrus plagiator (Nees) and Ephedrus persicae Froggat were encountered mainly on the plains at lower altitudes. Diuraphis noxia (Kurdjumov) was mainly recorded at higher altitudes in Iran along with its dominant parasitoid species, Diaeretiella rapae (MIntosh). The fact that Iran is close to the presumed area of D. noxia origin (Central Asian submountains) could be very important in further biological control efforts against this pest aphid. According to our results, Aphidius ervi Haliday is a very rare parasitoid of cereal aphids in Iran, which contrast with its high abundance in Europe and North America.

“…Although the role of cereal aphid predators and primary and secondary parasitoids has been studied in different ways (Jones, 1972;Dean et al, 1981;Powell, 1982;Hellenius, 1990;Höller et al, 1993;Pike et al, 1997;Pankanin-Franczyk & Sobota, 1998;Thies et al, 2005), the parasitoids of aphid specific predators are usually overlooked. Based on our findings of a wide spectrum of parasitoids of aphid specific predators, we conclude that they are an important factor reducing the abundance of predators and cannot be overlooked when considering the effectivity of predators in reducing cereal aphid densities.…”

Abstract. During 1989During -2006 the number of live aphid, mummies, aphid specialist predators and their parasitoids in cereal fields in Serbia were recorded. S. avenae and M. dirhodum were the most common, both on wheat and rye crops. Maximum numbers of cereal aphids were detected between the end of May and the middle of June. A low percentage of mummified aphids was recorded during May and June, but increased rapidly at the beginning of July, when aphids left the wheat crop. Here, we record over 60 species of cereal aphid natural enemies, including primary and secondary parasitoids, aphid specific predators and a wide spectrum of their parasitoids in Serbian cereal crop systems. Aphidius uzbekistanicus Luzhetzki, Aphidius rhopalosiphi De Stefani, Aphidius ervi Haliday and Praon gallicum Starý were the most abundant species of primary parasitoids. Of the secondary parasitoids, six species were dominant with Asaphes suspensus (Nees) and Dendrocerus carpenteri (Curtis) generally the most often recorded. Coccinella septempunctata L. was the most abundant coccinellid and syrphid flies were represented by 11 species, two of which, Sphaerophoria scripta (L.) and Episyrphus balteatus (DeGeer), were the most common.

“…In this study, four braconids recovered (A. avenaphis, A. ervi, L. testaceipes, P. yakimanum) were either native or long-time residents of North America (Mackauer and Finlayson, 1967;Krombein et al, 1979;Pike et al, 1997) and were not introduced for D. noxia control (Prokrym et al, 1998). In comparison, during and within a few years after the release program for D. noxia control, two native or resident parasitoids (A. ervi and L. testaceipes) were recovered (Brewer et al, 2001;Burd et al, 2001).…”

“…The canisters were maintained at room temperature (»24°C) and »70% RH under a constant light for 2 weeks. The contents of the collection vials were examined under a dissection microscope for species identification using keys and other materials found in Vockeroth (1992), Tanasijtshuk (1996), and Pike et al (1997). The contents of the canisters also were examined to further maximize the likelihood of detecting parasitoids and predatory flies associated with D. noxia.…”

Hymenopteran parasitoids and dipteran predators of Diuraphis noxia in the west-central Great Plains of North America: Species records and geographic range

Parasitoids and predatory flies were sampled in the wheat production region of the west-central Great Plains (southeastern Wyoming, western Nebraska, and northcentral Colorado) of North America using plant material infested with the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae). Samples were taken April through October in 2001 and 2002, which was 15-16 years after first detection of D. noxia and 5-6 years after the last release of natural enemies for its control in this region. The natural enemies detected were (in order of high to low detection frequencies across three states and 2 years): Aphelinus albipodus Hayat and Fatima (Hymenoptera: Aphelinidae), Eupeodes volucris Osten Sacken (Diptera: Syrphidae), Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae, Aphidiinae), Leucopis gaimarii Tanasijtshuk (Diptera: Chamaemyiidae), Aphidius avenaphis (Fitch), Aphidius matricariae Haliday, Diaeretiella rapae (M'Intosh), Aphidius ervi Haliday, Praon yakimanum Pike and Stary´(Hymenoptera: Braconidae, Aphidiinae), and Aphelinus asychis Walker (Hymenoptera: Aphelinidae). The results confirmed establishment of one of the 10 exotic parasitoid species released for D. noxia control (A. albipodus) in the west-central Great Plains. It is unknown whether detection of A. asychis, A. matricariae, and D. rapae can be attributed to exotic introductions or preexisting populations. Other species detected in this study have been previously documented from the western US, although the recognized distributions have expanded for A. avenaphis, L. gaimarii, and P. yakimanum compared to the first few years after initial detection of D. noxia. Thus, there is definitive establishment of one exotic introduced for D. noxia and considerable range expansion of preexisting species that prey upon D. noxia.
