AI Technical Summary
Technical Problem
The smooth surface of the white snow moth eggs causes the Trichogramma wasps to frequently slip while parasitizing them, reducing egg-laying efficiency and limiting their large-scale breeding and application.
Method used
Spraying a mixture of small particles such as starch or diatomaceous earth with polyvinyl alcohol water-soluble film onto the surface of snow lamp moth eggs reduces smoothness and improves the gripping ability of Trichogramma wasps.
Benefits of technology
It significantly improved the parasitism efficiency of Trichogramma wasps and the number of parasitized eggs per unit time, reduced breeding costs, and did not affect the offspring emergence rate or female ratio of the wasp species.

Abstract
This invention discloses a method for reducing the smoothness of *Tetranychus spp.* eggs to improve the parasitism efficiency of *Trichogramma pulcherrima* wasps, and also discloses a particulate mixture solution for reducing the smoothness of *Tetranychus spp.* eggs. The method is applied to the surface of the *Tetranychus spp.* eggs by spraying. This method increases the friction of the *Tetranychus spp.* eggs, effectively solving the problem of *Trichogramma pulcherrima* wasps frequently slipping on the eggs and having difficulty grasping them. This method is simple and easy to operate, significantly improves the parasitism efficiency of the wasp species, greatly reduces the breeding cost of *Trichogramma pulcherrima* wasps, and has significant application advantages and broad market demand.
