The number of phytophage eggs at the beginning of mass egg laying and during thereof is controlled by means of settling Trichogramm on the basis of 50000-100000 individuals per 1 ha. Caterpillars of younger 1-3 ages are controlled by means of using bacterial preparations, and controlling the hazard of caterpillars of the elder 4-6th ages, resistant to the action of bacterial preparations, is carried out by means of double settling of the entomophage Habrobracon hebetor Say.
