Survey and seasonal occurrence of aphid parasitoid species, particularly Aphidius matricariae, associated with cereal aphid species on wheat plants were carried out in different wheat regions in Egypt for
the two seasons1998/99 and 1999/2000.The survey revealed the presence of the primary parasitoids
species Aphidius matricariae Haliday, A. colemani Viereck, Diaeretiella rapae M’Intosh, Praon necans
Mackauer, Ephedrus persicae Froggott., and Aphelinus spp.and the hyperparasitoid species; Alloxysta
spp., and other cynipids, pteromalids (Asaphes and Pachyneuron), and Dendrocerus spp. associated with
different cereal aphid species in wheat fields. Highest percentage of total primary parasitoid species
(84%) and the lowest percentage of hyperparasitoid species (16%) were recorded at Sharkia Governorate, during season 1999/2000. Percentages of A. matricariae were higher during the first season than
those of the second season. Among the surveyed parasitoids species, the total percentages of A.
matricariae reached 42.8, 50.5, and 51.8%, in the first season, compared to 18.7, 14.2, and 6.1% in the
second season at Sharkia, Beni-Suef, and Sohag Governorates, respectively |
