在我国为害柑桔的螨类中,柑桔红蜘蛛(Panonychus citri McGregor)普遍发生严重。其年发生世代多,兼营两性生殖和孤雌生殖,因此繁殖迅速,发生量大,猖獗为害时可造成大量落叶、严重减产和削弱树势。目前鉴于国内(尤其我省)对红蜘蛛的其它防治措施还未进入实用普及阶段,即使从害虫综合治理(IPM)这一角度考查,化学防治对控制柑桔红蜘蛛的猖獗为害也是十分必要的手段并起着重要作用,但由于过去长期使用有机氯和有机磷类广谱农药,产生了诸如环境污染、杀伤天敌、害虫抗性等一 Among the mites that harm citrus in our country, Panonychus citri McGregor is widespread. Its generation more than generation, 兼营 bisexual and parthenogenesis, so the rapid propagation, occurrence of large, rampant damage can cause a large number of deciduous, severely cut production and weaken the tree potential. At present, in view of the fact that other control measures against red spiders in China, especially in our province, have not yet entered the stage of practical popularization, it is very necessary for chemical control to control the rampantness of red spider mites, even from the perspective of IPM Means and play an important role, but due to the long-term use of organochlorine and organophosphate broad-spectrum pesticides, resulting in such as environmental pollution, natural enemies of insects, pest resistance, etc.
