Green leaf hopper is one of the serious rice pests. Rice plant with GRH2 and GRH4 genes shows a high level of the resistance against this insect species. In this study, the mechanism for the resistance has been tried to wlucidated. Ten compounds including one peptide with D-form were isolated and identified as antifeeedants against her.

叶蝉是严重的水稻害虫之一。具有GRH2和GRH4基因的水稻对该害虫表现出较高的抗性。本研究对其耐药机制进行了初步探讨。分离并鉴定了10个化合物，其中包括1个d型肽。
