This study aimed to validate the nutritional superiority and safety of fermented coffee by products (CB) and fermented oyster mushroom cultivation by-products (OMCB) as alternative food sources for Protaetia brevitarsis larvae. Thus, we conducted a comparative analysis of the nutrient composition of the food sources and developmental characteristics of the larvae. P. brevitarsis larvae have traditionally utilized various by-products as food sources and are able to efficiently utilize these. The analysis of the nutrient composition of the food sources indicated that, in comparison to control group fermented oak sawdust (FOS), the content of crude protein was 2.2 folds higher in larvae fed with OMCB and 3.2 folds higher in larvae fed with fermented 50% CB + 50% OMCB (CB + OMCB). Moreover, the cellulose content, utilized as a nutritional source for the larvae, was 1.3 folds higher in the CB + OMCB group than in the control group. Significantly, the weight of larvae fed with OMCB and CB + OMCB increased 1.7–4.2 folds compared to those fed with FOS. Additionally, the survival rate of larvae before the formation of pupal cells was over 90% in all groups. Therefore, it was concluded that CB and OMCB contain various nutrients without harmful composition and have a larval growth-promoting effect. Consequently, they are considered appropriate dietary materials for P. brevitarsis larvae. This study enhances our understanding of by-product usages by P. brevitarsis larvae and confirms their potential as sustainable food resources.
