Mallada boninensis (Okamoto) eggs and first instar larvae were released thrice against Ateurocanthus woglumi Ashby at an interval of 15 days. Cumulative per cent reduction in the population of A. woglumi at the end of third release was recorded and the comparison was made between the treatments. The highest cumulative per cent reduction of 70.24 was recorded in malathion sprayed trees. Amongst various dosages/stages of M. boninensis, release of eggs @ 6 and 4 number/shoot recorded 36.72 and 34.65 per cent cumulative reduction in A. woglumi population and was found to be more effective than other dosages.
