Ectropis oblique (Prout) seriously damages tea plant and reduces tea quality. It is well documented that different tea cultivars [Camellia sinensis (L.) O. Kuntze] have diverse and complicated responds to the feeding stress caused by E. oblique. So to investigate the mechanisms of resistance to E. oblique by tea plant is of great importance for identifying resistance level of tea cultivars, exploring tolerant genetic resources against insects and creating new insect-resistance materials. The damage situation caused by E. oblique was firstly described, then the new achievements related to resistance mechanism to E. oblique by tea plant were summarized, and some problems in this field were pointed out, and the current research trends and prospects were analyzed.%茶尺蠖[Ectropis oblique (Prout)]危害严重降低了茶叶产量和品质。业已表明，不同茶树[Camellia sinensis (L.) O. Kuntze]品种对茶尺蠖取食的胁迫反应复杂多样，探究茶树对茶尺蠖的抗性机制，对于鉴定茶树抗虫性等级，发掘利用抗虫基因资源以及培育抗虫良种具有重要意义。本文从简述茶尺蠖危害概况入手，总结了当前茶树对茶尺蠖抗性机制研究的新成果，指出了目前茶尺蠖抗性机制研究中存在的问题，并分析了当前的研究动向与前景。
