摘要
洱海东岸面山造林区内,历年来鼠害十分严重,从1995年起进行了多次化学灭鼠工作,但鼠口密度一直没有得到有效控制。至使用植物性不育剂以来,试验区内鼠口密度得到了明显下降。因为植物性不育剂的作用原理与化学灭鼠剂相比具有根本性的区别,化学灭鼠剂是以杀死害鼠的个体来抑制鼠害的,而植物性不育剂是以控制和降低鼠类的出生率来抑制鼠害的。
Along the east coast of Erhai hill, afforestation area has been affected by forest rat, serious problems indeed. Since 1995, chemicals were used a lot to kill the rat but the density has not been ef- fectively controlled. Since the use of the plant sterile agent in the test area, the rat density was signifi- cantly decreased. The key point is that plant sterile agent operates by controlling the birth rate of for- est rate, whereas chemicals operate by killing the single entity.
