在广州地区的柑桔园,柑桔红蜘蛛的天敌有捕食螨、草蛉、食螨瓢虫、塔六点蓟马和蜘蛛类等。其中钝绥螨占60—80％。经过两年的试验证明,以利用钝绥螨为主,少量使用选择性农药和加强田间管理的综合措施,是防治柑桔红蜘蛛行之有效的途径,可长期控制其数量在防治指标以下,化学农药的用量也相应大大减少。 钝绥螨具有发育历期短,嗜食柑桔红蜘蛛,食料范围广,在植株上的分布与猎获物相一致等优良特性,可取得理想的防治效果。钝绥螨对三氯杀螨醇、石硫合剂、西维因、胶体硫、六六六、滴滴涕、巴沙、托布津等化学农药具有不同程度的抗性。 柑桔园的一种杂草——藿香蓟对稳定钝绥螨的种群数量有着重要的作用,它的花粉和在叶上的啮虫的幼虫可作为钝绥螨的食料。
Citrus orchards in Guangzhou, citrus red spider predators are predatory mites, grass mullet, food mites ladybugs, tower six-point thrips and spiders. Among them Amblyseius accounted for 60-80%. After two years of experiments, it has been proved that the comprehensive measures of using selective pesticides and strengthening the field management with Amblyseius acuminatum are the effective ways to prevent and cure citrus red spider mites, and the quantity can be controlled for a long time under the control index, The amount of chemical pesticides is also greatly reduced. Amblyseius has the characteristics of short developmental duration, citron spider mite, wide range of foodstuffs, distribution on the plant and the same with the hunt, etc., can achieve the desired control effect. Amblyseius mites have different degrees of resistance to dicofol, limestone, carvedilol, colloidal sulfur, BHC, DDT, Balsa, Topaz and other chemical pesticides. Ageratum, an herbaceous weed in citrus groves, plays an important role in stabilizing the population of Amblyseius spp. Its pollens and the larvae of the larvae on the leaves act as food for the Amblyseius spp.
