Abstract
Four egg and 24 larval parasitoids including one mermithid species have been identified fromHeliothis armigera collected at and around ICRISAT Center. Twenty one insect and five spider species have been recorded as predators ofHeliothis. The degree of parasitism varies according to the crop. Egg parasitism is absent on chickpea, and almost negligible on pigeonpea (0·3%). Most early larval parasitism occurs on pearl millet (50·7%), sorghum (49·5%), and chickpea (31·4%), whereas late larval parasitism occurs on pigeonpea (16·4%), and groundnut (11·5%).
The egg parasitoids, mostlyTrichogramma chilonis Ishii, and the parasitoids of small larvae, mostlyCampoletis chlorideae Uchida, are the most abundant natural enemies ofHeliothis in the study area.
