摘　　要：茶跗线螨是四川茶区最重要的害螨之一 ,通常采用化学防治方法去控制。但由于该螨个体小 ,生境隐蔽 ,繁殖快 ,防治难度大 ,有必要探索新的控制途径。本研究探索生物多样性与害螨之间的关系 ,结果表明 ,在茶园生态系统中引入新的植被后 ,茶园生物多样性增加 ,但并不一定具有对害螨的控制能力。试验中的李 +茶 ,梨 +茶 ,桃 +茶栽培模式 ,害螨的发生及危害与单植茶园几乎没有区别 ,其原因可能因为李、桃、梨等果树均为螨类的寄主之一。林 +茶模式中 ,由于林木的阴蔽度改变了茶园生态条件 ,该螨发生及危害明显降低。不同栽培模式对跗线螨的抑制效果依次为林茶 >梨茶 >桃茶 >李茶 >单植茶园。Yellow mite (Polyphagotarsonemus latus(Banks))is one of the very important pest mites of tea in Sichuan,China.It is difficult to be controlled by chemicals because of its small body,rapidly reproductive and hind habitate.It is necessary to find out a new way for its control.This paper dealt with the relationship between plant diversity and yellow mites occurrence.The results were as follows:When the diversity increased in the tea field by introduced non-tea plants,the mites damage changed.e.g.while plum,pear or peach were introduced in the tea field,the mites population and damage due to yellow mites changed;the damage greatly decreased while a crop tree interplanted with tea bush.That's because the temperature,humidity and sunlight shed changed.The control efficiency of mite varied with the kind of trees as follows:tree(cedar)+tea>pear+tea>peach+tea>plum+tea>single-tea field.
