Image showing drab colouration of the adult Tachinid fly.. Because tachinid flies do not kill the host until after the caterpillar has finished feeding, helicoverpa crop damage is not prevented... The tachinid fly Goniophthalmus australis lays microscopic eggs (measuring 0.2 mm each) onto the plant surface close to where a helicoverpa caterpillar is feeding so that the caterpillar eats the eggs and becomes a host...

Growers do not have access to varieties with resistance to the key exotic pests and disease... The project will proceed in two phases... The project is about optimizing pesticide sprayapplications by: identifying spray technologies and spray settings with low risk of spraydrift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides andtherefore minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacyagainst target pests...
