Banana Leaf Roller, Erionota torus Evans (Lepidoptera: Hesperiidae): A Destructive Insect Pest of Banana

Abstract

Banana leaf roller, Erionota torus Evans is a major devastating foliage pest of Musa spp. reported in several locations globally. It affects banana plant both during the vegetative and reproductive (flowering) stages. The main symptoms are incised and rolled-up leaves. The leaf roll can be extended to a length of 15 cm. The skipper larva's feeding activity causes significant harm to the banana leaves by rolling the leaf while feeding on it. Although banana plants can withstand up to 20% defoliation, a high infestation can cause the entire banana leaf to be damaged, leaving only the midrib intact. Defoliation by leaf roller larva will result in roughly 28% yield losses at a 50% defoliation rate. There is no much management practices are required, wherever the natural enemy’s activity is at peak.
