natural enemies

Catalogue: Broadacre Field Crops DAFF QLD
Ascovirus-infected larvae are small, pale and can look as though they have been grazing in one place, leaving small 'windows' in the leaf State of Queensland.. Some predators found commonly in crops will not feed on helicoverpa at all and some may only feed on certain stages (for example, larvae of a particular size, or only eggs)... Natural enemies will rarely eradicate all eggs or larvae, but may reduce infestations to below economic threshold if predators and parasitoids are not disrupted by broad-spectrum insecticides...

The best approach to managing helicoverpa is to use a combination of both chemical and non-chemical tools... By considering the ecology of H. armigera and H. punctigera , several key principles emerge that will assist in the successful and sustainable management of these pests... Insect-resistant genetically modified (GM) cotton has been developed to produce a highly specific toxin that kills helicoverpa larvae that feed on the cotton plant...
