Compositions and methods for controlling plant-parasitic nematodes using naturally derived fungal strains are provided. The compositions comprise one or more fungi selected from Trichoderma koningiopsis NC.184, Metarhizium NC.244, Clonostachys NC.261, Clonostachys NC.359, Clonostachys NC.297, an unidentified Hypocreales fungus NC.311, Pseudozyma pruni NC.423, Clonostachys rosea NC.480, Metarhizium anisopliae NC.374, Plectosphaerella cucumerina NC.438, or products, isolates, or extracts derived therefrom, optionally in combination with surfactants or additional active ingredients. Formulations include sprays, powders, granules, seed coatings, emulsions, and microencapsulated products. Methods of producing fungal materials and methods of applying the compositions to plants, seeds, or soil to reduce nematode populations are also provided. The compositions are effective against agriculturally important nematodes, including soybean cyst, root-knot, lesion, sting, and corn needle nematodes, and may improve plant health and yield. The invention enables biologically based nematode management for crops such as soybean and corn.

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.

This invention discloses a termite-killing dsRNA and its combination with Metarhizium anisopliae for termite control. The nucleotide sequence of the termite dsRNA is shown in SEQ ID NO.2. Inhibiting the expression of the termite taste receptor 14 gene (Gr14 gene) using RNAi significantly increases termite mortality. Spraying termites after inhibiting Gr14 gene expression using RNAi achieves a termite mortality rate of approximately 75%, thus it can be considered an effective method for termite control.
