A method for maintaining the sub-threshold numbers of lepidopterous phytophages of berry-fields includes using destroying techniques in agrocenoses. In the spring-summer period, at the beginning of mass egg laying of lepidopterous phytophages, double settling of Trichogramma of the species Trichogramma pintoi Voeg. onto bushes is carried. In the period of appearance of caterpillars of the 1-2ages single spraying of plants with aqueous solution of the preparation Gaupsin is carried out. In the period of appearance of caterpillars of the 3d and elder ages single settling onto bushes the ectoparasite Habrobracon (Habrobracon hebetor Say.) is carried out.
