none Enter An attempt was made to study the population dynamics of natural enemies of H. armigera under the prevailing agro-climatic conditions of Allahabad. A few parasitoids were found to be associated with the major insect-pest N. armigera. The parasitoids belonged to the order Hymenoptera viz. Campoletis chloridae (Uchida), Tetrastichus ayyari Rohwer and Brachymeria lasus (Walker) were found parasitizing the gram pod-borer. The data revealed that the parasitoid, C. chloridae made its presence felt throughout the cropping season, whereas T. ayyari and B. lassus were seen parasitizing at the later stage of the crop. These parasitoids if manipulated might prove to be a potential source of suppressing the population built up of H. armigera. Brachymeria lasus (Chalcididae): [Parasite]. Tetrastichus ayyari (Eulophidae): [Parasite]. Campoletis chloridae (Ichneumonidae): [Parasite]. Helicoverpa armigera (Noctuidae): [Host].
