简介：
Overview
This study presents a protocol utilizing a mealworm (Tenebrio molitor) bait system for the isolation and selection of entomopathogenic fungi (EPF) from soil samples. The method incorporates a formula for effective conidia number (ECN) to identify high stress tolerant EPF, aimed at enhancing pest microbial control.
