Cecidogenous Crotonothrips (Thysanoptera)- Memecylon interactions: host relations, nutritive tissue, tissue dynamics and cecidogenetic patterns

Abstract

The host relations of Crotonothrips with Memecylon on the criterion of gall formation appear interesting. In the light of the morphogenetic courses that the susceptible host organ, the leaf, show, an attempt has been made to assess their functional efficiency in terms of structural adaptations envisaging the organisation of a nutritive zone, and tissue dynamics taking Memecylon edule, Memecylon lushingtonii, and Memecylon umbellatum as models.
