Cnaphalocrocis medinalis Guenée is a noxious rice pest during cultivated periods. Cnaphalocrocis medinalis moths lay eggs on leaf surfaces, and larvae longitudinally roll the leaves to hide inside the leaf buds and feed on the upper epidermis and mesophyll tissues. In this study, we evaluated the female oviposition preference and larval performance of C. medinalis on six insect-resistant and six insect-susceptible rice genotypes. Female moth choice and no-choice oviposition preferences were studied. The number of eggs laid on the leaf varies among selected rice genotypes; however, female adults prefer to lay more eggs on both some resistant and susceptible rice genotypes. Furthermore, newly hatched larvae showed no observed differences in preference for both specific resistant and susceptible rice genotypes. The time taken by larvae for leaf selection varied significantly after inoculation on different genotypes at the maximum tillering and heading stages of rice plants. Compared with susceptible genotypes, leaf selection time was prolonged in resistant genotypes. In addition, the time taken for folding primary vegetative and flag leaves by larvae varied among the selected rice genotypes; larvae required more time to fold leaves of resistant than susceptible genotypes. In host antibiosis tests, larval and pupal survival and pupal weight were higher in susceptible than resistant genotypes. The results showed that the time required by larvae for leaf rolling and host antibiosis should be considered as the most crucial factors for rice genotypes resistant to C. medinalis.
