山楂叶螨对常用杀螨剂的敏感性研究

Studies on the Susceptibility of the Hawthorn Spider Mite\%(Tetranychus Viennensis\%) to Commonly Used Acaricides

采用玻片浸渍法 ,测定了山楂叶螨雌成螨对常用杀螨剂的敏感性。结果表明 ,雌成螨对供试杀螨剂的敏感性依次为齐螨素 >三唑锡 >甲氰菊酯 >三氯杀螨醇 >哒螨灵 >毒死蜱 >双甲脒 >苯丁锡 >水胺硫磷 >四螨嗪。与国内报道的敏感基线比较 ,晋中山楂叶螨种群对水胺硫磷、甲氰菊酯和三氯杀螨醇表现为中等抗药性 ,对双甲脒产生了低水平抗药性 ,而对毒死蜱和苯丁锡仍很敏感。在此基础上提出了山楂叶螨抗药性综合治理的措施。

The sensitivity of the hawthorn spider mite, \%Tetranychus viennensis\% Zacher, from Taigu, Shanxi Province, to commonly used acaricides was tested with slide-dip method recommended by FAO. The result showed that the susceptible order was abamectin>azocyclotin >fenpropathrin>dicofol>pyridaben>chlorpyrifos>amitraz>fenbutatin oxide>isocarbophos>clofentenzine. Compared with the susceptible baselines from references, it was found that the pest has developed medium level resistance to fenpropathrin, dicofol and isocarbophos,and low level to amitraz. But it was still susceptible to chlorpyrifos and fenbutatin oxide. Integrated resistance management for this pest were discussed.
