红蜘蛛是柑桔的主要害虫之一。由于桔园长期大量使用化学农药,致使红蜘蛛的抗药性越来越强,许多化学农药对其防效差,甚至无效,有的农药对其生长繁殖还有刺激作用(如菊酯类农药)。为此,近年来我们应用土农药防治柑桔红蜘蛛,收到了良好的效果。 Red spider is one of the major pests of citrus. Due to the long-term use of chemical pesticides in orange orchards, the resistance of spider mites is getting stronger and stronger. Many chemical pesticides have poor or even ineffective effects on them. Some pesticides have stimulating effects on their growth and reproduction (such as pyrethroid pesticides) . To this end, in recent years, we use pesticides to control citrus red spider, received good results.
