This invention relates to the field of microbial technology. This invention provides a strain of *Metarhizium anisopliae* JGMH-2401, classified as *Metarhizium anisopliae*. Metarhizium anisopliae The strain was deposited on March 3, 2026, at the China General Microbiological Culture Collection Center (CGMCC), Institute of Microbiology, Chinese Academy of Sciences, No. 3, Courtyard 1, Beichen West Road, Chaoyang District, Beijing, with accession number CGMCC NO:42519. This invention also provides the application of the described *Metarhizium anisopliae* JGMH-2401 in the control of scarab beetles. This invention combines the application of *Metarhizium anisopliae* JGMH-2401 as an inoculant with straw return to the field. During the feeding on contaminated straw, the beetle comes into contact with and becomes infected by the strain, shifting the control window forward to before the beetle larvae overwinter, thus achieving effective overwintering control.

The invention relates to a pesticide composition containing sophocarpidine and metarhizium robertii and application of the pesticide composition, and belongs to the field of biopesticides. The compound composition is a water dispersible granule containing sophocarpidine and metarhizium robertianum, and specifically comprises 15% of metarhizium robertianum MrCb01 pure sporopollen, 5% of sophocarpidine, 5% of a wetting agent NP-10, 4.5% of a dispersing agent Borresse NA, 10.5% of a dispersing agent Prowet WG20, 2% of an anti-ultraviolet agent L-ascorbic acid, 20% of a disintegrating agent ammonium sulfate, 2% of an adhesive sodium carboxymethyl cellulose and 36% of filler diatomite.
