Panikachu (Colocasia esculenta) is one of the most important tuber crops commercially grown in all parts of the country. The crop has good potential for production in the wet season and can survive a certain period in flood water. It is a good source of carbohydrate and other nutrients, supplementing a diet that tends to be deficient during this particular period. The whole plant of panikachu including leaves, petioles, stolon and rhizomes are edible (Saha and Hussain 1983). Among the insect pests infesting Panikachu, leaf hopper, Amrasca biguttula biguttula Ishida; aphid, Aphis gossypii Glover; leaf roller, Tetranychus spp. and common cutworm, Spodoptera litura are reported earlier.
