The larval survivorships were almost similar with the control group except a group with 70% of BSG. We compared survivorship, larval weight, developmental duration, pupation rate, and pupal weight of five different groups of T. We prepared five different diets with various BSG content, 0, 10, 30, 50, and 70% of heated air dried BSG with wheat bran. In this study, we investigated the effects of brewer's spent grain (BSG) on the growth of mealworm larvae to reduce the rearing cost. Conventionally, mealworms raised on wheat bran. Mealworms, Tenebrio molitor (Coleoptera: Tenebrionidae), are widely used as food sourcefor animal rearing as well as human diet.
