当今茶叶安全生产面临害虫为害猖獗和农药污染的突出问题，害虫生态调控是实现农业可持续发展的重要途径之一，其核心是保护自然天敌资源，使其长期有效地调控害虫。为在茶园有效实施害虫生态管理策略，各茶区积极开展了茶树病虫害及其天敌资源的调查，在摸清茶园中天敌资源种类及其种群动态和自然控害能力的基础上，如何合理规划茶园生境布局和环境条件，以更好保护天敌资源和强化其对害虫的自然控制功能进行了积极的探索。本文对茶园生态系统生物多样性的特点进行分析，并对近年来在茶园利用生物多样性生态调控害虫方面的研究报道进行综述，以期为提升其保益控害的生态服务功能，更好地在茶园应用生态管理措施提供理论依据和实践指导。

Tea production currently faces the critical problems of pest damage and pesticide contamination, and therefore are in urgent need of sustainable pest management strategies. Ecologically-based pest management is one way of reducing pesticide use while maintaining high yields. This is achieved by constructing an ecological environment that provides important ecosystem services, including supporting natural enemy populations to enhance the biological control of pests. In order to effectively implement ecologically-based pest management in tea plantations, pest species and their natural enemies have been extensively identified, while the abundance and diversity of natural enemies, their population dynamics and their natural capability to control pests have been well documented. There has also been considerable research on how to manipulate habitats to better maintain and enhance populations of the natural enemies with the goal of achieving long-term sustainable regulation and control of pests in tea plantations. This paper reviews recent research advances on the use of biodiversity in tea plantations to regulate pests, in order to provide both a theoretical basis and practical guidance for improving ecosystem functions and services, and promote the application of ecologically-based pest management strategies in tea plantations.
