A method to form a wintering reserve of species of the genus Trichogramma includes forming favourable conditions in natural biocenoses such that along the perimeter of agrocenoses in forest belts a consortium plant group with a gooseberry brush nucleus in the centre is formed, which is settled with the Exapate congelatella Cl. (Lepidoptera, Tortricidae) on the basis of 25-35 individuals per brush where populations of Trichogramma develop and diapause. Nearby at a distance of 1-1.5 m hawthorn, black thorn and spiraea are planted.
