Waite G.K.
In each of 3 seasons, crops grown under a system known to be viable further south outyielded the district average, at less cost. Non-disruptive insecticides were used to control the key pests Heliothis punctigera and H. armigera, so that predaceous species were permitted to survive until at least mid-season. After this, parasitism of Heliothis spp. eggs by Trichogramma sp. increased to significant levels. The pest management approach has since been adopted commercially on a large scale.
