Performance and Virulence of the Entomopathogenic Fungi Beauveria bassiana Grown in Media Derived from Biodegradable Agricultural Wastes Enriched with Cricket Powder

Entomopathogenic fungi (EPF) can be an eco-friendly alternative to control pests. To produce large-scale EPF requires underused economical substrates containing high carbon and nitrogen; hence the production could cost-effective. This study investigates effects of organic agricultural waste, i.e., rice bran, husks, tea dregs, wheat bran enriched with cricket powder as culture media on mycelial growth, sporulation, conidia viability Beauveria bassiana fungal pathogenicity towards Spodoptera litura larvae. For each type medium, five independent cultures B. are treated replications. grown a PDA medium is control. shows that became most suitable waste support mass virulent bassiana. Therefore, used appropriate for
