Chilo partellus (Swinhoe) larvae were found to be parasitised by Cotesia flavipes Cameron and pupae by Tetrastichus howardi (Oliff) and Xanthopimpla stemmator (Thunberg) in Bangalore during February to May, 2001. The extent of larval parasitisation by C. flavipes varied from 3.3 to 24.5 per cent. Pupal parasitisation due to T. howardi and X. stemmator varied from 2.5 to 9.5 and 0 to 10 per cent, respectively.
