Method for morphological determination of preimaginal stages of development of Trichogramma entomophage

摘要

The invention relates to agriculture, in particular to a method for morphological determination of preimaginal stages of development of Trichogramma entomophage.The method, according to the invention, consists in that the host eggs parasitized by the Trichogramma entomophage are treated with 3.0% aqueous solution of hydrogen peroxide at a temperature of 80…100°C, for 8…10 min until the shell of the eggs becomes transparent, the eggs are examined under stereoscopic microscope with an increase of 16…32 times and are determined the stages of development of Trichogramma entomophage.
