Heliothine moths are agricultural pests worldwide, attacking many food and fibre crops and costing billions of dollars each year in crop damage and control measures. This text is a base-line resource into Helicoverpa/Heliothis control methods. General, concise summaries of the agricultural importance of heliothines, their biology, systematics, and morphology are given. An up-to-date summary of heliothine phylogeny - based on morphological and molecular information - provides a framework for organizing and interpreting biological information about all heliothine moths and has worldwide relevance. The 38 Australian heliothine species are detailed with identification information an d individual species treatments. All species are illustrated. Nomenclatural information of interest to taxonomists appears in an appendix, and includes full checklist and detailed information of type specimens. The Cd-Rom contains a database of all 14,800 Australian heliothine specimens examined. It also carries nomenclatural information suitable for loading into bioinformatics packages, and images of type specimens.
