This species is one of the largest stored-product beetles (adult body length between 12 and 20 mm) that is commonly found infesting stored agricultural products 6. Among the most promising insect species for industrial utilization and commercial large-scale production is the yellow mealworm, Tenebrio molitor L. Over the last few years, “insect farming” has attracted considerable scientific attention, as insects are considered an alternative and sustainable nutrient source for animal feed and human food 1, 2, 3, 4, 5. molitor larvae, with a high protein content of the substrate usually resulting in a high protein content of the larvae. Feeding on selected substrates exerted an impact on the nutrient composition of T. Similar effects were observed for larval development. In general, adult reproduction was clearly favoured by most amylaceous substrates tested, which was in contrast to the tested legumes on which fewer offspring were produced. molitor larvae that fed on various selected substrates. Finally, proximate composition was calculated to determine the nutrient components of the feeding substrates tested and the T. The efficiency of ingested food conversion was calculated for each substrate. After this time, the vials were opened, and the larvae of each vial were separated from the feeding substrate, counted and weighed as a group. At the end of the 1 week period, all adults were removed, and mortality was determined then the vials were further incubated for additional 9 weeks. molitor adults were introduced in plastic vials containing 30 g of each commodity. We evaluated the suitability of forty-four commodities (i.e., cereal flours and meals, non-flour, cereal commodities, legumes and various commodities of vegetative and animal origin) as oviposition and feeding substrates for the yellow mealworm, Tenebrio molitor.
