STUDIES ON THE STEM GALLS OF CEPHALANDRA INDICA

Manu Rani Paul

Abstract :

 The stem galls in Cephalandra indica (common name – Ivy gourd) of family Cucurbitaceae is the result of association of the plant with an insect Neolasioptera cephalandrae (Order – Diptera, Family – Cecidomyiidae). The gall formation was the response of the plant to the stimulus induced by the feeding of phytophagous insect by producing abnormal growth resulting in physiological disturbance of the stem tissues. The stems had undergone considerable morphological and anatomical changes. The gall formation was due to the hyperplasia and hypertrophy of the cells of the stem. Non sporulating stage of a fungus was also found in this gall this helps in nourishing the larvae. Different developmental stages of the insect such as egg larvae and adult were found in the gall chamber of the stem. The insect and plant association were observed beneficial only to the insect.
