Resumo: Morphological, anatomical and biochemical alterations in foliar galls of Alstonia scholaris R. Br. induced by the insect Pauropsylla tuberculata (Psyllidae) are described and quantified. Galls occur isolated or agglomerated on the abaxial surface of the leaf. The insect along with the egg deposits some physiologic fluid which act as a stimulant for the induction of the gall. This stimulus brings about hypertrophy followed by hyperplasia of cells next to the location of the deposited eggs. The psyllid presents three nymphal instars, from eclosion of the egg to the adult. Hyperplasia in the palisade cells is very distinctly noticed. Hypertrophy followed by hyperplasia takes place and brings about elevation of hypodermal and palisade parenchyma which undergoes repeated anticlinal divisions. Neoformation of phloematic bundles were distinctly noticed close to the site of infection. With an increase in the growth of the gall, chlorophyll content in the gall tissue decreases. A steady increase of sugar content is noticed. The immature galled tissue showed almost two fold increases in the protein content. The mature galled tissue showed a very high increase in the proline content compared to the immature galled tissue indicating a stressed condition of the galled tissue.
