Trichogramma (T. pretiosum, T. brassicae and T. minutum spp.) are tiny parasitic wasps that have a wingspan of 1/50th of an inch. They are a very efficient destroyer of the eggs of more than 200 species of moths and butterflies (Lepidoptera) which are leaf eaters in their caterpillar stage. Examples of such garden pests include corn earworm, cutworm, cabbage looper, armyworm, borers and codling moth caterpillar. Available March 1st thru September 1st.
DIRECTIONS FOR USE:
Shipped as pupae in host eggs, glued to one inch by one inch paper squares, Trichogramma arrive ready to hatch out as adult wasps. Release when moths are first present and periodically thereafter. Release 5,000 (1 square) per 5,000 square feet weekly, for 3-6 weeks.
Note: Ants can be a problem, eating the eggs on the squares if found — placing them in strategic areas should prevent this. Hanging each square from a piece of thread is a solution.
