This project has led to a significant advance in our understanding of the feeding behaviour of the adult heliothis moth. It has used detailed studies in ecology and behaviour of H.

Nowadays, most of us are aware that natural enemies (parasites and predators) sometimes play an important role in the control of pests attacking our crops.

Any agent which reduces damage caused by heliothis is a valuable asset.

During the 1991-92 season, a 1 ha block of unsprayed raingrown cotton near Dalby was sampled for parasite activity in heliothis larvae.

Recent research has indicated that two species of native egg parasitoids, Trichogramma (Trichogrammanza) carverae Oatman and Pinto and Trichogrammatoidea bactrae Nagaraja, have potential as biological control agents o
