Abstract:
The effect of feeding damages induced by the leaf folder, Cnaphalocrocis medinalis (Guenee) at various damage levels on the biochemical parameters of rice leaves was investigated. The biochemical profile of rice leaves damaged by a leaf folder was studied for quantitative and qualitative variations in chlorophyll, phenol and carotenoid using standard biochemical procedures. The tests were carried out on a rice variety called TN1 that is susceptible to the insect. The result revealed that with increase in infestation by C. medinalis resulted in decreased chlorophyll a, chlorophyll b and total chlorophyll content in rice leaves. The similar trend was observed for carotenoid content with increase in infestation. The phenol was found increased amount in infested leaves as it was a component of plant resistance.
