Process for mass production of the Trichogramma evanescens W. trichogramma (variants)

摘要

The invention relates to agriculture, in particular to the mass production of useful insects, used for plant biological protection.Summary of the invention, according to the 1-st variant of the mass production of the Trichogramma evanscens W. trichogramma, consists in multiplication thereof on eggs of the European grain moth Sitotroga CerealellaO., ageing 46-48 hours preliminarily irradiated with gamma rays in a dose of 200…300 Gy at the temperature of 23…25°C and a relative air humidity of 75…85%. According to the 2-nd variant, the trichogramma mass production consists in its multiplication on eggs of the European grain moth SitotrogaCerealella O., ageing 70…72 hours preliminarily irradiates with gamma rays in a dose of 350…650 Gy in the same conditions.The result of the invention consists in increasing the trichogramma quality and in saving the moth and trichogramma eggs.
