The research given may be similar to the situation created in nature, after heavy dew, after rain, after irrigation, for rice plants, which grow in water, etc., when the leaves of the plants are wet and the pest's eggs are in the water. Our experience has shown that in watery conditions Trichogramma evanesces can move on water, find the pest's eggs and parasitize them, where the percentage of parasitism was 71%. In extreme conditions the moth eggs of cereals aged 24-26 hours were treated at a temperature of 40-70℃, the time of treatment with hot water was: 20 and 40 seconds each variant, where the hatching of the larvae continued until the temperature of 60℃.
