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...
