【摘要】 应用浸叶法、点滴法和滤纸药膜法对黄曲条跳甲药剂敏感性测定结果的重复间变异系数比较表明,用点滴法测定黄曲条跳甲成虫药剂敏感性的重复性最好,变异系数为6.42%;其次为浸叶法和滤纸药膜法。利用点滴法和浸叶法测定了4个菜区黄曲条跳甲成虫对毒死蜱、丁硫克百威、氯氰菊酯的敏感性,结果表明点滴法和浸叶法测定结果均能一致反映出黄曲条跳甲田间种群的药剂敏感性水平。更多还原

【Abstract】 The susceptibility of striped flea beetle (SFB) to insecticides was examined with three kinds of monitoring techniques including leaf-dipping, dropping and filming methods, among which dropping method, with a value of 6.42% of coefficient of variation, was considered best due to its high reproducibility. Also, the susceptibility of SFB from 4 regions was tested to chlorpyrifos, carbosulfan and cypermethrin via dropping and leaf-dipping method, both of which could be applied to produce reliable results.更多还原
