Life Cycle and Abundance of Rice Leaf Folder, Cnaphalocrocis medinalis (Guenee) - A Review

Abstract

The Rice leaf folder, (RLF) Cnaphalocrocis medinalis (Guenee) is widely distributed in rice growing areas in all over the world. The leaf folder has been considered a miner pest of rice growing areas but after the existence, high yielding and Basmati rice varieties increasing the importance of these pests.  Feeding rates of the first three larval instars rice leaf folder on rice plants were significantly lower than those of the fourth and fifth instars. The first three instars consumed less than 10% of the larva's total consumption. Feeding also decreased with increasing plant age. To understand about life cycle and management’s tactics is help to reduce the yield losses. In present review articles discusses about life cycle and abundance of rice leaf folder.
