The parasitoid complex of several lepidopteran pests were studied in maize plantations in the Southeast Anatolian Region of Turkey during 2003-2004. Apenteles sp., Bracon hebetor (Say.), Chelonus oculator Panzer, Meteorus rubens Nees (Hym.: Braconidae), Conomorium patulum Walk. (Hym.: Pteromalidae), Diadegma crassicornis (Gray.) subsp. africator Aubert (Hym.: Ichneumonidae), Euplectrus sp. (Hym.: Eulophidae), Exorista larvarum (Linnaeus), E. xanthaspis (Wiedemann) Gonia bimaculata Wiedemann, Drino imberbis (Wiedemann), Pseudogonia rufifrons (Wiedemann), and Linnaemya neavei Curran (Dip.: Tachinidae),were reared from field-collected larvae. Mythimna loreyi (Duponchel) (Lep.: Noctuidae) was for the first time found to serve as a host for Diadegma crassicornis (Gray.) subsp. africator (Hym.: Ichneumonidae).
