A method for protecting apple-tree plantations from damages of codling moth (Laspayresia pomonella L.) such that in the spring-summer period at the beginning of egg-laying of females of the codling moth three settlings of Trichogramma, Trichogramma dendrolimi Mats. species, are carried out in an equivalent of 80, 160 and 100 females per one tree. In addition, after the second settling of Trichogramma, two settlings of the egg caterpillar codling moth parasite Ascogaster (Ascogaster quadridentatus Wesm.) on trees, with an interval of 10-12 days, is carried out in an equivalent of 50 and 70 females per one tree. Furthermore, in the period of rebirth of caterpillars of the codling moth, two sprayings of the trees with the biological preparations Carpovirusin 0.3 kg/ha and Lepidocide c.p. (concentrated powder) 3.0 kg/ha are carried out with an interval of 8-10 days.
