The value of unsprayed. strip crops as nurseries for beneficials in dryland cotton on the Darling Downs
Abstract
We are currently evaluating unsprayed strip crops planted beside dryland INGARD cotton as nurseries for beneficial arthropods. In the first season of trial work (1999/2000) lablab was evaluated as a nursery (Scholz et o1. 2000). While lablab harboured some species of predators, it supported few Trichogramma egg parasitoids. Trichogramma wasps are considered important beneficials on the Darling Downs and a nursery crop that supports them, as well as other beneficials, may be useful for managing heliothis and other pests. Consequently, during the 2000/01 cotton season we evaluated unsprayed sorghum, maize and soybean strips as beneficial nurseries for adjacent lNGARD cotton.
