One of the major objectives of the cotton industry is to reduce dependence on insecticides. This may be achieved by incorporating parasitoids into the pest management strategy. Parasitoids are wasps or flies that "attack" other insects. The "attack" means that the parasitic wasp or fly lays an egg inside the eggs, larvae or pupae of a host insect (i. e. Helicoverpa spp. ). Once the egg of the wasps or fly hatches, it feeds on the internal organs of the host species (i. e. Helicoverpa eggs, larvae or pupae) eventually killing it. The eggs, larvae and pupae of Helicoverpa are attacked by several native parasitoids that rely on Helicoverpa for survival. In order to place greater reliance on parasitoids for Helicoverpa spp. control we need to understand how to increase parasitoids abundance in cotton.
