The invention discloses an experimental method for using trichogramma to prevent and control sunflower stem borers and an implementation scheme of the experimental method. The experimental method includes dynamic analysis experiments of adult population of the sunflower stem borers, screening of trichogramma species and good strains, screening of advantageous trichogramma dendrolimi good strains and control effect comparison experiments on preventing and controlling the sunflower stem borers in a beekeeping period. The implementation scheme acquired through the experimental method includes variety selection of trichogramma, making of bee cards, and determining of the number of beekeeping, beekeeping quantity, beekeeping time, beekeeping method and beekeeping environment requirements. The experimental method and the implementation scheme thereof have the advantages that the designed technical scheme reaches the domestic advanced level, and considerable economic benefit and obvious ecological benefit are obtained.
