摘要
柑桔红蜘蛛、锈壁虱是柑桔园中的主要害虫,常规的防治方法主要依赖于化学防治,利用胡瓜钝绥螨(Amblyseius cucumersis),通过人工释放手段进行生防,释放后3个月生防效果调查,平均'黑果率'控制在2.70%～3.63%内,害螨控制率达89.6%～92.7%,年降低农药使用次数40%～60%.
As we know Panonychus citri Mcgregor and Phyllocoptruta oleivora (Ashmead) are the main harmful lirimg things to orange trees. Farmers often use chemicals to kill them. Now we have find Amblyseius cucumersis is the important enemy of the harmful mites. If we have some of them live on the orange trees. After 3 months the experiment shows that only 2.70~3.63 percent of the orange trees are harmed; about 89.6~92.7 percent of the harmful mites can be killed. The times of spraying (chemicals) can be reduced by 40~60 percent. Per year.
