柑桔红蜘蛛危害一直是世界柑桔生产上的突出问题,我省在1964年以前仅有零星地区发生。由于广泛应用有机氯防治柑桔虫害,红蜘蛛逐渐严重。20年来我省柑桔区先后推广了内吸磷(1059等)、三氯杀螨醇和三氯杀螨砜等药剂防治,由于药剂种类少,连续单纯使用一种药剂,对发育期短,年世代数多的红蜘蛛,使用3～5年即产生抗药性。因此对病虫种类多的柑桔要做好红蜘蛛的防治,当前除积极探索以保护与利用天敌的防治以外,还要结合使用选择性农药(不伤害天敌的药剂)和农业技术措施的综合治理,才能彻底收效。为此必须不断筛选出更多的新杀螨剂,以供轮换使用,缓和虫害产生抗性,这是当前比较有效的控制
Citrus red spider harm has been a prominent issue in world citrus production, the province occurred in only sporadic regions before 1964. Due to the widespread use of organic chlorine to control citrus pests, spider mites gradually worsened. In the past 20 years, Citrus District of our province has successively promoted the control of the internal absorption of phosphorus (1059, etc.), dicofol and dicofol and other agents. Due to the small variety of medicaments, a simple and continuous use of one kind of medicament can shorten the growth period and generation age The red spider, the use of 3 to 5 years that produce resistance. Therefore, the species of pests and insect pests to do a lot of red spider control, the current active in addition to actively explore the protection and use of natural enemies of prevention and control, but also with the use of selective pesticides (agents that do not harm natural enemies) and agricultural technology synthesis Governance, in order to fully effective. For this purpose, more and more new acaricides must be continuously screened for alternate use to mitigate pest and disease resistance, which is currently more effective control
