Aim of the study: The ubiquitous grain pest Corcyra cephalonica Stainton (Lepidoptera: Pyralidae) damages godowns and warehouses. Compared to Ephestia kuehniella and Plodia interpunctella, C. cephalonica pest potential is sometimes underestimated. Recent research shows that non-chemical management measures can successfully replace chemical pest control for farms. Thus, the most common fungal entomopathogens can control insects of diverse orders.

Methods: The plants B. bassiana, M. anisopliae, L. lecanii and P. lilacinum were taken from the ground and used at different amounts to treat C. cephalonica larvae in the lab. Statistical Package for the Social Sciences (SPSS), ver.16.00 SPSS Inc., USA, was used to do probit analysis on the concentration mortality rates and make correlations.

Results: Entomopathogenic fungus B. bassiana, M. anisopliae, L. lecanii and P. lilacinum were isolated from soil and treated on C. cephalonica larvae. B. bassiana proved effective. All four plates had protease, amylase, lipase, and chitinase clearance zones. This zone of clearance showed that B. bassiana culture filtrate produced protease, amylase, lipase, and chitinase. Negative impacts included short-lived adults with malformed bodies.
