| 【目的】探明‘中黄1号’茶园中主要害虫及其天敌的群落结构，对于采取有效措施防治茶园主要害虫及其天敌的保护利用具有重要参考价值。【方法】本研究于2020年-2021年采用检叶法、盆拍法、黄板诱集法和室内观察法对‘中黄1号’品种茶园害虫及其天敌进行系统调查，利用群落多样性分析和时间格局分析方法解析了‘中黄1号’茶园害虫及其天敌的构成。【结果】群落结构组成结果显示，‘中黄1号’茶园群落组成有害虫9目23科28种，天敌8目24科40种；两年群落多样性指数以及均匀度均较稳定。主要优势害虫为茶园叶蝉和茶棍蓟马Dendrothri psminowai，优势天敌为蜘蛛类。时间格局分析表明茶园主要害虫及其天敌群落的时序结构分为4个阶段，不同时段内主要害虫及其天敌的发生特点有明显差异，但两年的同一时段发生的主要害虫及其天敌差异较小。【结论】本研究的结果有助于阐明品种茶园害虫与天敌群落关系，并为茶园害虫的防治及天敌的利用提供理论依据。 |

| 【Aim】The community structure of the main pests and their natural enemies in the "Zhonghuang No. 1" tea garden has important reference value for taking target measures to prevent and control the main insect pests, as well as the conservation and utilization of their natural enemies. 【Methods】The classification and statistics of pests and natural enemies were recorded by leaf inspection method, pot tapping method, yellow sticky trap method and laboratory observation methods from 2020 to 2021. The composition of pests and their natural enemies was analyzed by using the methods of community diversity analysis and temporal pattern analysis. 【Results】The analysis of community structure composition revealed that the community composition of "Zhonghuang No. 1" tea garden included 28 species, 23 families and 9 orders of pests and 40 species, 24 families and 8 orders of natural enemy. The community diversity and evenness indices remained stable over the past two years. The dominant species of pests were leafhopper and Dendrothri psminowai, while the natural enemies of the dominant species were spiders. The temporal patterns of the main pests and their natural enemy communities were divided into four stages in the seasonal dynamics. The occurrence characteristics of the main pests and their natural enemies in different periods were significantly different, but minimal variation between the same periods across two years. 【Conclusion】The results were helpful to elucidating the relationship between pests and natural enemy communities in tea gardens. As well as provided theoretical basis for the prevention and control of pests and the utilization of natural enemies in tea gardens. |
