Thus, this fungus had low pathogenicity to Corcyra cephalonica larvae. Which similar to the results from Somodra (2003) evaluated Beauveria, Metarhizium and Isaria with Corcyra cephalonica larvae in the laboratory. The results, only Beauveria and Metarhizium caused the virulence to Corcyra cephalonica larvae but didn’t report the results of Isaria.
