METHOD FOR OPTIMIZING BIOLOGICAL CONTROL OF FRUIT MOTH POPULATIONS IN GARDENS

摘要

A method for optimizing biological control of fruit moth populations in gardens provides for spraying trees with biological preparations. Once feeding of caterpillars of fruit moths is finished, in fruits and at the beginning of migrating thereof into tree crowns into places of diapausing and wintering tree trunks, vegetable remains and soil surface near trunks, with a diameter of 85-, are treated with a 3 % aqueous solution of the biopreparation "Pecilomin". In addition, in the egg-laying period of fruit moth females of the first generation three settlings of a parasite of fruit moth eggs, a laboratory culture of Trichogramma, Trichogramma dendrolimi Mats. species, are carried out with an interval of 7-8 days in an equivalent of 100, 120 and 80 females of the first class quality per one tree. Furthermore, at the beginning of mass rebirth of caterpillars of fruit moths from eggs two sprayings of trees with an aqueous solution of the preparation "Viryn HIAP" are carried out with an interval of 6-7 days in an equivalent of 0.25- per .
