摘　　要：Recently N-glycosylation was found to be required for the postembryonic development and metamorphosis of the holometabolous beetle Tribolium castaneum. However, the role of N-glycosylation in the development of hemimetabolous insects is unknown. To further elucidate the role of N-glycosylation in the development of insects, a functional characterization of the N-glycosylation-related genes (NGRGs) was performed in a model insect for hemimetabolous development, namely the brown planthopper Nilaparvata lugens. In this project, we report the effects of RNAi-mediated silencing of 15 NGRGs on the postembryonic development of N. lugens. Two major observations were made. First, interruption of the early steps of N-glycan processing led to a lethal phenotype during the transition from nymph to adult as was observed in T. castaneum. Second, we report here on an essential function for the α-1,6-fucosyl transferase in the ecdysis event of N. lugens between nymphal instars, since gene-silencing by RNAi led to failure of ecdysis and subsequent mortality of the treated insect.
