A total of 5 parasitoids i.e. 3 larval parasitoids and 2 pupal parasitoids were recorded parasitizing the maize stem borer, Chilo partellus (Swinhoe). The larval parasites were active throughout the season with occasional peaks of up to 52.26% parasitism. Cotesia flavipes, a larval parasitoid proved to be the most abundant and showed highest percent host mortality followed by Cotesia chiloni and the least parasitism was shown by Sturmiopsis inferens. Among pupal parasitoids, maximum parasitism was shown by Xanthopimpla stemmator and the least parasitism was shown by Tetrastichus spp. Therefore, larval parasitoids are more able to cause host mortality/ parasitism than pupal parasitods. Cotesia flavipes is the best larval parasitiod and can be effectively used as a biological control in the integrated pest management (IPM).
