Aphid parasitoids (Hym.: Aphidiidae, Aphelinidae) from the Yemen Arab Republic.
Because of the climatic characteristics of the country, most of the samples taken during a survey for aphids and their parasites carried out in the Yemen Arab Republic in 1979-1980 were collected from irrigated plots in the highlands. Aphidius colemani Vier.ck was the dominant parasite and was reared from Acyrthosiphon gossypii Mordv. and Aphis craccivora Koch on Vigna sp., from Acyrthosiphon pisum (Harris) on Vicia faba, from Aphis fabae solanella Theo. and Myzus persicae (Sulz.) on Solanum spp., from Brachycaudus helichrysi (Kalt.) on Myosotis sp., from Diuraphis noxia (Mordv.) on Triticum persicum, barley and triticale, from Rhopalosiphum maidis (Fitch) on sorghum, and from Schizaphis graminum (Rond.) on barley. The only other parasites reared from aphids were a species of Aphelinus reared from R. maidis on sorghum, and Praon exsoletum (Nees) and Trioxys complanatus Quilis reared from Therioaphis trifolii (Monell) on lucerne.
