The Role of Beneficials - Are Some Predators Better Than others at Finding and Consuming Helicoverpa?

Gregg, P, Daly, J, Davies, I, Johnson, M (Australian Cotton Growers Research Association, 1998-08-14)

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).

Using immundot assay to test which predators feed on Helicoverpa armigera (Hubner) in Australian Cotton

Gregg, P, Trowell, S, Daly, J, Johnson, M (Australian Cotton Growers Research Association, 1998-08-14)

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).

The effects of chlorfluazuron (Helix TM) on the development of the parasitoid Microplitis demolitor (Braconidae) and its host Helicoverpa armigera (Noctuidae)

Annetts, R, Murray, D, Gregg, P (Australian Cotton Growers Research Association, 1996-08-16)

Microplitis demolitor (Hymenoptera: Braconidae) is a mid to late season parasitoid of Helicoverpa spp. larvae. Female M. demolitor prefer to lay eggs in second instar larvae.
