Abstract

A method to control the number and harmfulness of silkworm populations in forest nurseries includes a direct effect on populations of harmful insects. Monitoring and identification of species composition of silkworm populations, determining the terms of the beginning and mass egg-laying with the following settling a parasite of silkworm eggs, preliminary grown in a biolaboratory, in particular Trichogramma, is carried out by means of visual observations. In the period of appearance of silkworm caterpillars of the first age a single settling of imago of a parasite of silkworm caterpillars, in particular Apanteles, is carried out. In the period of appearance of silkworm caterpillars of the fourth age re-settling of the Apanteles is carried out.
