METHOD FOR CONTROLLING NUMBERS OF INJURIOUS ARTHROPODAS IN BERRY FIELDS

摘要

A method for controlling the numbers of injurious arthropodas in berry fields includes methods directed on lowering the numbers of pests. In berry-field plantations in the spring–summer period double settling of Trichogramma (Trichogramma pintoi Voeg.) is carried out on the basis of 20-25 females per one brush. In the period of emergence and mass expansion of caterpillars of elder ages and pupae of lepidopterous pests double settling of the parasite Dibrachus cavus Walk is carried out on the basis of 10-12 females per one brush. In the period of emergence of sucking pests double settling of larvae of junior ages of the common earwig (Forficula auricularia L.) is carried out on the basis of 4-6 individuals per one bush.
