Two sets were designed to determine the acceptance and prefer­ence of some lepidopterous hosts to be parasitized by Trichogramma ev­anescerrs and Trichografrotatoidea bactrae females which had been maintained on angoumois grain moth, Sitotroga cereaiella eggs (original culture) for more than 10 generations, In the first set, Trichogramma fe­male was offered the choice between acerealeila eggs (the original host) and those of each of the other five hosts pink bollworm Pec­tinophora gossypielta Saunders, spiny bollworm Eaoas ftsuiana Boised, black cutworm Agra ipsifor? Hufn, rice bran moth Corcyre cephalonica and Mediterranean flour moth Ephestia kuelygelia. Data revealed that fe­males of the two parasitoids accepted to parasitize eggs of the six lepi­dopterous species with different levels of preference. i.e., 2.0-2.9 con­tacts & 10.75-21.79 parasitized eggs by Teveroescens and 1.2-3.0 contacts & 6.04-32_46 parasitized eggs by Tbactrae . The two parasi­toid females didn't prefer S.cereatelia more than either of the remaining five hostes. In the second set. eggs of the six host species were ex­posed to Trkhogramma females, eggs of the six host species were also accepted for parasitism with different levels of preference. The accep­tance and preference behavior between the two parasitoids were insigni­ficet. While, P.gossypiefla eggs were the most preferred by females of the two species over those of the remaining five hosts.
