Abstract : The purpose of the present study was to understand the definite alteration of metabolic activity at cellular level in Mangifera indica leaf galls induced by Amradiplosis allahabadensis. A marked difference in the anatomy was observed between gall and normal tissue. Histochemical studies revealed highest activities of the enzymes and various metabolites in the hypertrophied cells. High content of metabolites viz. starch, cellulose, proteins, etc. were observed in gall tissues as compared to normal counter parts, similarly high enzymatic activities of acid phosphatase, polyphenol oxidase and peroxidase were observed in the leaf galls. A functional elaboration in the cells closer to the feeding site during cecidogenesis was evident. Their differential response of enzymes and metabolites at cellular level of the host proved advantageous to the gall forming insect.
