    • Abstract


      In all the three plants selected, viz.,Pongamia, Diospyros andArgeria there appears to be a specific reduction in riboflavin (B2), niacin, protein, protein nitrogen, soluble nitrogen and total nitrogen contents of gall tissues, thus perhaps indicating that the insect larvae may preferentially feed on these nutrients of the leaf. There also appears to be a general reduction in reducing sugar content although it is not so significant. Increased starch content is noticed inPongamia.
