在北美很多苹果与梨种植区研究并实施了以生物防治为基础,助以生理选择性杀螨剂以及其它仁果类病虫害化学防治的叶螨综合防治。这些方法的实施还没有完成。滥用生理选择性杀螨剂的现象相当普遍。近来已产生了对有机锡杀螨剂的抗性,有效杀螨剂的数量在急剧减少。几种试验性的杀螨剂如clofentezene hexythiazox,abamectin也许不久可以应用于生产,但如果这些药剂也被滥用,抗性也会很快产生。实施叶螨综合防治的一些策略及措施必须改变,建议增加现有研究,扩大推广教育,促进工业及生产者更好的合作。
Many apple and pear cultivation areas in North America to study and implement a biological control based on the help of physiologically selective acaricides and other pomegranate chemical control of pest spider mite integrated control. The implementation of these methods has not been completed. The abuse of physiologically selective acaricides is quite common. Recently, resistance to organotin acaricides has been produced, and the amount of available acaricides is drastically reduced. Several experimental acaricides such as clofentezene hexythiazox and abamectin may soon be available for production, but if these agents are also abused, resistance will quickly develop. Some strategies and measures for implementing the comprehensive prevention and control of spider mites must be changed. It is suggested that existing research be expanded to promote education and promote better cooperation between industry and producers.
