Mode of action
To locate host eggs, adult females use chemical and visual signals, such as egg shape and colour.Adult Trichogramma pretiosum lay their eggs in the Lepidopteran eggs.After about 8-9 days, the adult wasps emerge from the pupae and escape the Lepidopteran egg by chewing a circular hole in the eggshell.
Visual effect
The black layer inside the chorion and the exit hole are evidence of parasitism by Trichogramma.
