Studies on release and recovery of native parasitoids viz. Megastigmus sp and Aprostocetus gala Walker of eucalyptus gall wasp, Leptocybe invasa Fisher & La Salle, were conducted during 2008-09. The results indicated that there was a gradual increase in the per cent parasitization of these parasitoids under green house conditions. During November 2008, 10.83 per cent parasitization by Megastigmus was observed which increased to 23.27 per cent parasitization in September 2009 and 28.33 per cent parasitization during October 2009. The parasitization by Aprostocetus gala was to the extent of 16.45 per cent.
