近年银川、中卫、灵武、盐池等地的国槐、刺槐、白榆、杨、柳、白蜡及苹果树上普遍发生花球蚧。化学防治虽有一定效果,但花球蚧繁殖力强,稍一疏忽即可蔓延成灾。长期用药,又会使害虫产生抗药性,并造成环境污染。1979年发现北京举肢蛾幼虫寄生在花球蚧雌壳内,个别枝条寄生率达40%。为保护、利用天敌昆虫,并为综合防治提供依据,我们于1981~82年进行了观察研究。
In recent years, Yinchuan, Zhongwei, Lingwu, Yanchi and other places of Sophora japonica, locust, elm, poplar, willow, white wax and apple tree flower scale commonly occurs. Although there is a certain chemical control effect, but flower bill scale reproduction, a little negligence can spread disaster. Long-term medication, will make pests produce resistance, and cause environmental pollution. 1979 found Beijing parasites moth larvae parasitic flower gekko female shell, the individual branch parasitic rate of 40%. In order to protect and utilize natural enemies of insects, and to provide a basis for comprehensive prevention and control, we conducted an observation study in 1981-82.
