METHOD TO CONTROL THE AMOUNT OF LEAF-ROLLER MOTH

摘要

A method to control the amount of leaf-roller moth includes artificial rearing and settling parasite insects at small fruit fields. Settling the Trichogramma is carried out early in autumn in the second half of September in the period of beginning and mass egg-laying. The Trichogramma is settled at the stage of imago in eggs of a host insect in the lower part of a brush at a distance of 7-10 cm from the soil surface except that inside the brush 50% are arranged and at the edges by 25% of the Trichogramma from the used rate.
