为明确新化合物天维菌素的杀螨活性,浙江农林大学生物农药高效制备技术浙江省工程实验室、浙江海正药业有限公司研究人员采用叶碟喷雾法,测定了在室内天维菌素对朱砂叶螨、柑橘红蜘蛛及二斑叶螨的毒力,并研究了其制剂对螨类害虫的田间防治效果。结果表明,天维菌素对朱砂叶螨若螨和雌成螨均具有较高的毒力,其LC50分别为0.011、0.11mg(a.i.)/L,杀螨活性优于弥拜霉素、阿维菌素,但杀卵活性较差。田 In order to clarify the acaricidal activity of the new compound avermectin, Zhejiang Agriculture and Forestry University, Zhejiang Province Engineering Laboratory, Zhejiang Hisun Pharmaceutical Co., Ltd. researchers using leaf dish spray method, the determination of the indoor avermectin On the turf spider mites, citrus red spider and two-spotted spider mites virulence, and the preparation of mites pests on the field control effect. The results showed that the fungicide had higher virulence to both the mite and adult mite, the LC50 was 0.011,0.11 mg (ai) / L, respectively, and the acaricidal activity was better than that of mebemycin Vitexin, but oviposit less active. field
