摘要： 通过调查广西西林县古障有机茶园和黄果园常规茶园的最主要害虫和天敌分别为假眼小绿叶蝉和蜘蛛。在茶树生长季节，有机茶园的假眼小绿叶蝉数量比常规茶园少，蜘蛛数量比常规茶园多。有机茶园假眼小绿叶蝉和蜘蛛间的相关系数(r：0.2182~0.7355)比常规茶园的(r：0.1318)大，说明有机管理措施有助于天敌和害虫间形成相互制约关系。

Abstract: Empoasca(Emposaca)vitis(Gōthe)and spiders were the uppermost pest and natural enemies in Guzhang organic tea garden and Huangguoyuang conventional tea garden of Baise region, Guangxi province. In the organic tea garden, the population of Empoasca(Emposaca)vitis(Gōthe)was lower but the population of spiders was higher compared with the conventional tea garden. The correlation coefficient of the population dynamics between Empoasca(Emposaca)vitis(Gōthe)and spiders in organic tea garden(r：0.2182~0.7355)was higher than in conventional tea garden(r：0.1318),so organic management can help the interacting relation between pests and natural enemies and come to being.
