采用 FAO 推荐的浸渍玻片法,对宁夏高桥种群进行了敏感水平测定建立了山楂红蜘蛛对18种供试药剂的毒力基线。对山东云门山和山东莱阳种群进行了抗药性测定,结果表明,对三环锡、天王星、功夫、灭杀毙、水胺硫磷、灭扫利等10种农药表现非抗药性。连年多次施药的莱阳种群对氧化乐果、杀虫脒、对硫磷、三氯杀螨醇、乐果和久效磷产生了抗药性。其抗性分别为11.6、26.8、56.1、62.8、149.8和176.1倍。而采用乐果与杀虫脒、三氯杀螨醇与水胺硫磷交替轮换施药的云门山种群对乐果和三氯杀螨醇抗性明显降低,其抗性产生速度分别比莱阳种群低16倍和28倍。对三氯杀螨醇抗性很强的莱阳种群对混剂131—B 仅表现出轻度的抗药性。
The method of immersion slide recommended by FAO was used to determine the sensitivity of Takahashi population in Ningxia to establish a baseline of virulence for 18 tested agents. The resistance of Yunmen Mountain in Shandong Province and Laiyang Mountain in Shandong Province was tested. The results showed that the ten pesticides such as tricyclic tin, Uranus, Kung Fu, killing and killing, isocarbophos and forsythiaside showed non-resistance. The population of Laiyang, which was applied for many times in successive years, developed resistance to omethoate, chlordimeform, parathion, dicofol, dimethoate and monocrotophos. The resistances were 11.6, 26.8, 56.1, 62.8, 149.8 and 176.1 times, respectively. However, the populations of Yunmen Mountain that used dimethoate and chlordimeform, dicofol and alternamidine were significantly less resistant to dimethoate and dicofol, and their resistance rates were 16 and 28 times lower than that of Laiyang population respectively. Laiyang population, which is highly resistant to dicofol, showed only mild resistance to mixture 131-B.
