Abstract Microplitis demolitor Wilkinson is an important larval parasitoid ofHelicoverpa armigera (Hübner) andH. punctigera (Wallengren) in Australia. The effect of host plant on parasitism of second instarH. armigera byM. demolitor was investigated in a glasshouse experiment. Parasitism was low (0%) on chickpea. Moderate to high levels of parasitism (22.4% 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 spring generation ofHelicoverpa spp.
