The study of different life parameters of Trichogramma chilonis on eggs of Sitotroga cerealella (Olivier) fed on old and new varieties of wheat, maize and sorghumrevealed that S. cerealella adult emergence was higher (88 adults) on wheat new variety (Atta Habib). In old varieties, T. chilonis parasitism was highest (41.20%) on wheat, while lowest (34.80%) on sorghum. On new varieties, parasitism was minimum (44.60%) on wheat while maximum (59.80%) on maize. T. chilonis adult emergence (85.40%) was highest on eggs derived from wheat old variety whereas, in new varieties, lowest adultrnemergence of 73.20% was recorded in wheat. T. chilonis male emergence was highest (41.40%) on maize old variety, while lowest (34.20%) on wheat old variety. On new varieties, male emergence of 22.80 was recorded on wheat, whereas value of 30.40 was recorded for maize and sorghum. The results revealed that maximum parasitism and adult emergence by the wasp was observed in maize new and highest females were counted from the wheat new variety.
