Australian cotton production relies heavily on the use of pesticides for control of Helicoverpa spp. As a result insecticide resistance has become a major problem (Daly and Paschalidis 1994).

With the advancement in production of monoclonal antibodies (MAbs) that are species specific the use of serological assay as a tool for assessing natural enemies has increased during the last decade (Greenstone 1996).
