Abstract：The rice leaf folder, Cnaphaolcrosis medinalis Guenée, is an important migratory rice pest in the main rice-growing areas of China. However, it is a very difficult species to successfully rear in the lab, which is a major hindrance to research on its biology, ecology and the development of control strategies this species. We analyzed and compared nutritional components of the leaves of susceptible and resistant varieties of rice at different growing stages. The key nutritional factors that influence the development, survival and fecundity of C. medinalis were found and appropriate proportions of each nutritional ingredient in an artificial diet calculated. The results provide a scientific basis for the development of an artificial diet for C. medinalis.
