Abstract : Field studies were conducted in Maharashtra, India, during 1987-88, to record natural enemies of Idioscopus niveosparus, I. nagpurensis, Amritodus atkinsoni and Amrasca splendens, which are pests of mango. Last-instar nymphs of Amritodus atkinsoni, I. niveosparus and I. nagpurensis were parasitised by an unidentified species of dryinid wasp. No parasitoids were recorded from Amrasca splendens. Predators of nymphs and adults of I. niveosparus, A. splendens and Amritodus atkinsoni included 11 species of spider [Araneae] and the coccinellid Menochilus sexmaculatus [Cheilomenes sexmaculata]. Predation occurred during October-November and January-April.
