Sustainable Management Strategies for Rice Leaffolder, Cnaphalocrocis medinalis (Guenée): Progress and Prospects

The rice leaffolder, Cnaphalocrocis medinalis (Guenée), is a major migratory insect pest in paddy fields that damages rice by folding and feeding on leaves, causing chlorophyll loss and resulting in significant yield losses when its population density exceeds an economic threshold. Sustainable pest management requires ‘green plant protection’ solutions. Advances in science and technology have introduced numerous green methods for sustainable management of the rice leaffolder. This paper reviews recent research advancements in rice leaffolder management, such as ecological regulation, healthy cultivation, behavioral regulation, biological control, and rational insecticide application. Based on accurate monitoring and early warning systems, rice leaffolder management can incorporate comprehensive green control products, green control technologies, and control modes. This paper provides prospects for discussing the future of rice leaffolder management, achieving sustainable management of the rice leaffolder, and ensuring rice production safety.
