Sorghum is extremely attractive to ovipositing heliothis (Hencoveipo armigero) moths. Some cotton growers on the Darling Downs are intercropping cotton with sorgum because they believe that sorghum may act as a beneficial nursery, and that the beneficials may move into the adjacent cotton. Here we report on a trial comparing the levels of heliothis egg parasitism and predator abundance in cotton adjacent to intercropped sorghum. The heliothis egg parasitoid Trichogramma pretioswm was released into half of the sorohum, and the levels of egg parasitism in the adjacent cotton were compared between the release and non-release sections of the field.
