Product details
Mode of action
Adult female parasitic wasps of Trissolcus basalis lay an egg in a host egg. Larvae develop inside the host egg, and after pupation the adult emerges from the host egg by biting a hole in the lid of the stink bug egg.
Visual effect
Parasitised host eggs turn beige-brown after about a week and shiny grey-black after about 10-12 days. Nezara eggs from which Trissolcus has emerged have an opening with a serrated edge. Unparasitised eggs have a nice round edge.

Dosage
The release of Greenshield should be done once stinkbug eggs are laid or preferably 2 weeks in advance. Release 100 wasps per hectare every 4 to 6 weeks for the period that either stinkbug egg laying takes place, or the nuts or fruits are prone to damage. Consult a Koppert advisor or a recognised distributor of Koppert products for advice on the best strategy for your situation.
