中文摘要：
化学农药防治茶树病虫害效果迅速,然而其长期使用所带来的＂3R＂问题直接影响茶叶的可持续发展。随着茶叶质量安全问题日受关注,生物防治作为病虫害综合治理的一个重要组成部分,在茶树病虫害防治体系中有着广阔的应用与发展前景。概述生物防治的定义、演变及茶树病虫害生物防治的主要措施如害虫天敌、植物源农药、微生物制剂、信息素及昆虫生长调节剂等在茶树上的应用研究进展,总结茶树病虫害生物防治存在的不足,并对茶树病虫害生物防治提出展望：充分利用生防微生物来拮抗茶树病原菌、构建载体植物系统防治茶树虫害、充分发挥天敌对茶园害虫的调节作用、加强茶树生物农药的研究及其产品的开发推广应用。
英文摘要：
The control effect of chemical pesticides on tea diseases and pests is rapid, but its long-term use brings ＂3R＂ issues directly affecting the sustainable development of tea. With the attention of tea quality and safety issues day, biological control as an important part of integrated pest management has turned into a broad prospect in the tea diseases and pests control system. This paper elaboratethed the definition and evolution of biological control, outlined the major types of biological control and their research on the application of tea, such as natural enemies of pests, botanical pesticides, microbial agents, pheromones and insect growth regulator, etc, summarized deficiencies of tea biological control, then proposed the following ideas and suggestions for biological control of tea diseases and pests：make full use of biocontrol microbes to antagonize tea pathogens, construct vectors against tea pest plant system, give full play to natural enemies of pests regulatory role for tea, strengthen research and bio-pesticides tea product development and application, to provide the reference for further research and application of biological control of tea diseases and pests.
