Based on the current situation of chemical pesticides used at tea gardens and in order to make a scientific tea pest management in Zhouning, the application of the lime sulphur to control the overwintering pests at tea gardens was conducted during January 2008 in 2 different altitude level tea gardens, Makeng and Qibu of Zhouning.
为探讨周宁茶园有害生物的科学治理,减少农药残留,提高茶叶产量与品质,在全面调查周宁茶园农药使用现状的基础上,于2008年1月,选择周宁的玛坑、七步两种不同海拔高度的茶园,应用石硫合剂进行冬防处理,探讨比较了不同处理区的茶园害益虫种群结构及数量、茶叶产量及农药残留量等,取得如下结果:周宁县茶园节肢动物群落可以划分为3个亚群落,它们分别是:由假眼小绿叶蝉、蚜虫、黑刺粉虱、蓟马、螨类、螽斯、蝗虫、蟋蟀、象甲、甲虫类、蝽类、树虱类等组成的害虫亚群落;由跳虫、蚊类、甲螨和蝇类等组成的中性昆虫亚群落;由蜘蛛、瓢虫、黑刺蚁、蚂蚁、隐翅虫、螳螂、食蚜蝇等捕食性天敌和由姬蜂、茧蜂、蚜茧蜂、小蜂、金小蜂、姬小蜂、跳小蜂、蚜小蜂、缨小蜂、赤眼蜂、扁股小蜂、黑卵蜂、分盾细蜂、瘿蜂、锤角细蜂等寄生性天敌共同组成的天敌亚群落。
