Transformation Capability Optimization and Product Application Potential of (Coleoptera: Cetoniidae) Larvae on Cotton Stalks.

Cotton stalks (CS) are a potential agricultural biomass resource. We investigated the use of CS as a feed for Lewis larvae and the resulting frass (larvae dung-sand) as a fertilizer. Based on a three-factor experiment (decomposition inoculant, fermentation duration, and cattle manure ratio), the optimal parameters for the transformation of CS using larvae were determined as 40-50% of cattle manure, the use of VT inoculant and a fermentation duration of 25-30 days.
