The Queensland Department of Primary Industries is currently investigating IRM techniques for heliothis in cotton and some vegetable crops. The research includes evaluation of native egg parasitoids as biological control agents of heliothis. In 1994 a strain of Trichogramma pretiosum was obtained from heliothis eggs on sunflowers at Kununurra (Western Australia). The results of initial field testing of this species of wasp as an in inundative bio control agent are provided below.
