Abstract: The present application relates to the technical field of biology, in particular to a beauveria bassiana strain with high ultraviolet radiation resistance as well as a directional mutagenesis method therefor and use thereof. The beauveria bassiana strain with high ultraviolet radiation resistance of the present application has an accession number of CGMCC No.22466, and is deposited on Jul. 5, 2021. The strain is obtained by means of taking beauveria bassiana wild strain CGMCC No.13566 as an original strain and performing multiple rounds of repeated stress and directional screening under simulated sunlight UVB sub-lethal radiation, and has high resistance to ultraviolet radiation. A fungal insecticide prepared by adopting the strain can be well applied to pest green prevention and control in all weather.
