Understanding the life cycle and behaviour of Helicoverpa armigera and H. punctigera improves our chances of managing this pest sustainably... Recent strategies such as area-wide management (AWM) and integrated pest management (IPM) aim to restrict the build-up of Helicoverpa populations to below damaging levels... Cotton Catchment Communities CRC has information related to integrated pest management including: impact of insecticides and miticides on predators in cotton current insecticide resistance management strategy integrated pest management guidelines for Australian cotton...

Normal helicoverpa egg on left, black parasitised egg on right.. H. armigera has developed resistance to a wide range of insecticides a number of products are now registered for both species that have reduced impacts on natural enemies in the crop... All stages of the helicoverpa lifecycle are attacked by a wide range of predators, parasitoids and pathgens, and conserving these in the crop through the avoidance of broad-spectrum insecticides can help prevent/minimise the need for insecticide treatments...

The name Helicoverpa refers to two species of moth: Helicoverpa punctigera and H. armigera , the corn earworm... The likely magnitude of these influxes of H. punctigera can be estimated by monitoring the breeding areas in inland Australia... The computer model uses current local temperatures to calculate the rate of development of pupae in the soil, and predicts the timing of emergence of moths...

Late instar Helicoverpa larvae can vary greatly in colour and markings State of Queensland.. Life cycles of H. armigera and H. punctigera take 4-6 weeks from egg to adult in summer, and 8-12 weeks in spring or autumn... Not all pupae that form in late summer go into diapause: a proportion continues to develop, perhaps emerging during winter, or early in spring...
