Sugarcane is an important cash crop in many tropical and subtropical regions of the world. However, the sugarcane internode borer is a significant pest that causes substantial economic losses to sugarcane farmers. The larvae of the sugarcane internode borer feed on the inner tissues of sugarcane stalks, leading to yield losses ranging from 20% in moderate infestation to 50% in severe infestation. In this article, we provide an overview of the sugarcane internode borer and explore various control strategies to help farmers minimize its damage.
They are whitish larva with brown heads, which can be identified by the longitudinal stripes and dark spots on the dorsal side of the body. Waterlogged conditions around the shoot canes favor the buildup of sugarcane internode borer. Low temperature and high humidity also favor the outbreak of internode borers.
The larvae of the sugarcane internode borer tunnel through the stem and feed on the cane horizontally causing damage to the cane by breaking them.
Scientific Name: Chilo sacchariphagus indicus
