Entomopathogenicity assay in silkworm larvae. One milliliter of a conidial suspension (105/mL) of each fungal isolate was spread on potato dextrose agar or synthetic nutrient agar, and the plates were incubated for 4~10 days at 25℃. Fifth-instar silkworm larvae were allowed to walk on the plates for 12 hr (upper) and then moved to fresh Petri dishes. The photographs (lower) were taken 7 days after relocation. S. lanosoniveu, Simplicillium lanosoniveu; B. bassiana, Beauveria bassiana; F. graminearum, Fusarium graminearum.
