Abstract
Microplitis demolitor Wilkinson is an important larval parasitoid of H elicoverpa armigera (Hubner) and H. punctigera (Wallengren) in Austral ia. The effect of host plant on parasitism of second instar H. armiger a by M. demolitor was investigated in a glasshouse experiment. Parasit ism was low (0%) on chickpea. Moderate to high levels of parasitism (2 2.4% to 75.4%) were recorded on sorghum, sunflower, maize, cotton and soybean. The results suggest that releases of larval parasitoids into chickpea are unlikely to enhance parasitismlevels during the first spr ing generation of Helicoverpa spp.
