Abstract

This chapter describes the distribution, population dynamics, host range and feeding preference of H. armigera and H. punctigera, the 2 most important Helicoverpa pests in Australia; host selection by Helicoverpa spp.; extent of damage on crops caused by Helicoverpa spp.; management of Helicoverpa spp. in Australia, with emphasis on the development of transgenic cotton harbouring a Bacillus thuringiensis gene, and implementation of an integrated control system incorporating INGARD (transgenic cotton); and role of the wild relatives of chickpea as sources of resistance to Helicoverpa.
