    • Abstract

       

      Campoletis chlorideae Uchida was the most common parasite emerging from the larvae ofHelicoverpa armigera (Hub.) collected during 1974–83 from almost all of its crop and weed hosts from Andhra Pradesh, Karnataka and Maharashtra. In most years, parasitism was highest in September and lowest in May. At ICRISAT Center, during 1977–83, the average percentage parasitism of first to third instar larvae, which are only parasitised byCampoletis chlorideae, was 44·2 on sorghum, 33·1 on chickpea, 32·6 on pearl millet, 7·1 on groundnut and 4·2 on pigeonpea. Parasitism in pesticide-treated crops was lower than in untreated crops. Ten species of hyperparasites were recorded from cocoons ofCampoletis chlorideae. Hyperparasitism was around 40% on cereals and 10% on legumes.
