Entomopathogenic fungi, such as ${it Metarhizium anisopliae}$, are economically important agents for integrated pest management programmes of insect pests. However, negative effects of temperature, such as heat stress that exceeds 35 $$^{circ}$$C, can have serious deleterious effects on conidial germination and persistence, vegetative growth, sporulation, and/or the infection process in these entomopathogenic fungi. In this study, we attempted to enhance thermotolerance in a model entomopathogenic fungus, ${it M. anisopliae}$, by mutagenesis using ion beams or $$gamma$$ rays and evaluated the relative virulence of the resulting mutants compared with the wild-type isolates. In conclusion, ion beams and $$gamma$$ rays are useful tools for improving biological characteristics, such as thermotolerance and fungicide-tolerance, in entomopathogenic fungi, but the mutants obtained in this study must be carefully evaluated for unpredictable negative side effects.
