Abstract
A midge,Odinadiplosis odinae Mani induces galls along the midribs of the leaflets ofLannea coramandelica (Hoult.) Merr. (=Odina wodier Roxb.). Gall initiation takes place at a very early stage of leaf development, incited by the larvae from the superficially deposited eggs, migrating into the leaf tissue. Bulk of the gall is formed by the proliferation of the interfascicular or parenchymatous ground tissue. Vascular bundles occur widely separated and during the early stages of cecidogenesis, a few atypical tracheary elements appear which later develop into a very complex anastomosing network of vascular elements around the larval chamber with the maturation of the gall. The functional nutritive zone becomes sclerenchymatous with the ageing of the gall.
