Abstract
The sugarcane internode borer, Chilo sacchariphagus indicus (Kapur), is a major constraint to sugarcane production in tropical and subtropical regions, causing significant yield and quality losses. Its cryptic feeding habit within cane internodes makes early detection difficult and reduces the effectiveness of conventional control measures. This review synthesizes current knowledge on the biology, ecology, host range, and damage potential of the pest, with particular emphasis on climatic interactions influencing its population dynamics. Factors such as temperature, humidity, and cropping practices play a crucial role in pest incidence and seasonal abundance. The multivoltine nature and overlapping generations further complicate management strategies. Integrated Pest Management (IPM), combining cultural practices, biological control agents, resistant varieties, and need-based chemical applications, offers a sustainable solution. Advances in pest monitoring, pheromone-based techniques, and climate-resilient strategies are also highlighted to enhance effective and eco-friendly management of this economically important pest.
