Individual releases of 19 000-387 500 adults of Trichogramma pretiosum Ril./acre on up to 48 acres of cotton at College Station, Texas, resulted in parasitism of eggs of Heliothis zea (Boddii) and H. virescens (F.) averaging from 33 to 81%, with some movement of parasites up to 400 ft within 2 days.
