Experiments were conducted to determine the best nutritive source to be used for improving the quality of Trichogramma evanescens (Westwood) reared on eggs of Sitotroga cerealella (Olive). Various nutritive solutions were tested: pure sugar cane honey (Blackstrap Molasses), pure bee honey, 10% sucrose solution, 10% yeast extract solution, a mixture of sugar cane honey with yeast extract solution and water. Longevity, fecundity, percentage of parasitoid emergence, sex ratio (female percentage) and general productivity were investigated. Trichogrammatids fed on pure sugar cane honey parasitoized the highest number of eggs (58.2 eggs/ female), lived the longest life span (5.35days) and produced the highest percentage of emerged adults (96.86%) with more female offspring (78.17%). Unfed females parasitoized the lowest Sitotroga eggs (30.55 eggs/ female) and lived the shortest life span (1.8 days). The least percentage of emerged progeny was produced when parents were fed on mixture of sugar cane honey and yeast (87.77%), whilst females fed on yeast only produced the lowest rate of female offspring (61.82%). Generally, the highest productivity of T. evanescens reached 44.07 females/ female by feeding adults on pure sugar cane honey, while reduced drastically to 19.60 females/ female when adults were unfed.
