Diet Composition Influences Growth Performance, Bioconversion of Black Soldier Fly Larvae: Agronomic Value and In Vitro Biofungicidal Activity of Derived Frass

In recent years, the larval stage of Hermetia illucens, commonly known as black soldier fly (BSFL), has been used to promote circularity agri-food sector by bioconverting organic waste into biomass which a livestock feed. A secondary byproduct this process is frass that can be an fertilizer. This study compared two different plant-based diets on characteristics well performance, nutritional composition, and reduction efficiency. fruit/vegetable/bakery waste-based diet supplemented with brewery (FVBB) was control Gainesville (GV) reference fed BSFL under standard conditions. The results demonstrated NPK some macro micronutrients in both frasses are comparable commercially available fertilizers. It shown microorganisms present from inhibit mycelial growth several plant pathogens through production antifungal and/or anti-oomycetes compound(s) (antibiosis). also had positive effect individual mass (162.11 mg), bioconversion rate (13.32%), crude lipid (35.99% dry matter) content. reared reduced feedstock matter 67.76% very short time (10 days), promising solution for food management.
