ROLE OF CARBOHYDRATES AND PROTEINS IN MAXIMIZING PRODUCTIVITY IN ALPHITOBIUS DIAPERINUS (COLEOPTERA TENEBRIONIDAE)


Abstract


Among all Tenebrionidae beetles Alphitobius diaperinus is considered a good choice for high-scale facility production of feed and food. It is widely considered that studies regarding the impact of the different dietary components on growth performances are very few and focused only on certain aspects, e.g. problems connected to the harmfulness of this species for stored products (rearing to test insecticides, studies about dietary preferences regarding different cereals). The real role of the different dietary components was never evaluated in order to better comprehend how to project diets that maximize productivity (maximum number of specimen as function of time). Research on the role of proteins and carbohydrates ascertained that a high protein content is required to obtain the best growth performances for this species. Carbohydrates also play a key role, though secondary to proteins.

The diets thus obtained establish an important starting point for future formulations aimed at obtaining useful insects for feed and also for human consumption, soon to be legalized worldwide.
