This invention relates to the field of insect control, specifically to the Paecilomyces lilacinus strain XI-5, and the extraction and identification of crude toxins produced by secondary metabolites of Paecilomyces lilacinus strain XI-5. This invention confirms that the secondary metabolites of Paecilomyces lilacinus strain XI-5 produce cyclosporine C. Cyclosporine C has a stomach poison effect on adult whiteflies. Twenty-four hours after application, the LC50 concentration of cyclosporine C against adult whiteflies was 31.75 µg / ml; compared to the control group, the LC30 concentration of cyclosporine C resulted in a decrease in oviposition / fertility in female whiteflies.

The invention belongs to the technical field of insect pest control, and particularly discloses a complex microbial inoculant for preventing and treating insect pests and application thereof.The complex microbial inoculant is prepared from, by weight, active ingredients and auxiliary materials, the active ingredients comprise 5-8 parts of bacillus thuringiensis, 4-6 parts of beauveria bassiana, 3-5 parts of metarhizium anisopliae, 2-4 parts of bacillus subtilis, 2-3 parts of bacillus amyloliquefaciens and 1-3 parts of paecilomyces lilacinus, the auxiliary materials comprise the following components in parts by weight: 1-2 parts of a surfactant, 0.5-1 part of a protective agent, 2-3 parts of a nutrient synergist and 30-40 parts of a carrier. According to the complex microbial inoculant, multiple functional microorganisms and synergistic components are reasonably matched, comprehensive and efficient prevention and control of scale insects, red spiders, aphids and fruit borers are achieved, and the complex microbial inoculant is environmentally friendly and safe to durian growth. The defects that durian pest control depends on chemical pesticides, and the control effect of microbial agents is single and unstable in the prior art are overcome.

The present application relates to the technical field of pesticides, and provides a pesticide composition containing Paecilomyces lilacinus and application thereof in killing root-knot nematodes.The pesticide composition containing Paecilomyces lilacinus comprises fungus powder and modified chitosan in a mass ratio of 5:3-9:1, the modified chitosan is obtained by modifying chitosan with a phosphoric acid compound, and the fungus powder comprises Paecilomyces lilacinus, Trichoderma harzianum, Bacillus cereus and Bacillus polymyxa.Through the technical scheme, the problem of poor control effect of Paecilomyces lilacinus preparation on nematodes in the related art is solved.
