摘要： 通过调查结果，广西百色地区有机茶园中主要病虫害的种类包括假眼小绿叶蝉、茶跗线螨、茶黄蓟马、茶蚜和茶饼病、茶炭疽病。假眼小绿叶蝉在4、7月份有两个发生高峰；茶跗线螨和茶黄蓟马早春发生较重。各种害虫都具有一定的趋嫩性，其中茶黄蓟马在茶树顶部的种群密度与其它位置差异显著。根据各病虫害的生物学习性，采取了强采及植物源药剂相结合等方法，起到了良好的防治效果。

Abstract: In 2003~2004, invetigations on the plant diseases and pest communities in organic Oolong Tea orchard were carried out in Baise.
