Bagaço de malte como componente alimentar para criação de Gryllus assimilis (ortoptera: gryllidae)

Abstract

The present study investigates the biological parameters of crickets (Gryllus assimilis) fed a malt bagasse-based diet, aiming to assess the feasibility of this food industry by-product as an alternative to the standard diet proposed by the FAO. The developmental time of juvenile stages, nymph mortality, adult weight, and egg fertility and viability were analyzed. Crickets were reared in specific cages under controlled temperature and humidity conditions and fed two distinct diets. Data collection occurred regularly to monitor insect development and health. Results indicate that malt bagasse is a viable food component, promoting efficient development in juvenile stages, controlled mortality, adequate adult weight, and good egg fertility and viability. Compared to crickets fed the FAO standard diet, those fed the malt bagasse diet showed similar performance. It is concluded that utilizing food industry by-products such as malt bagasse for insect rearing is economically viable and sustainable, contributing to food security and sustainability. This method holds promise as an alternative in the food market, contingent upon adherence to appropriate regulations.
