【摘要】 用滤纸药膜法测定了二氯苯醚菊脂、溴氰菊酯、毒死蜱、马拉松以及氯丹对黄肢散白蚁（Reticulitermesflaviceps）的接触毒性，结果表明在1－1000ppm范围内，五种药剂都对白蚁具有击倒作用；在相同的浓度下，药剂间存在着显著性差异；溴氰菊酯、毒死蜱对黄肢散白蚁的KT（50）明显小于氯丹。更多还原

【Abstract】 The contact toxicity of Reticulitermes flaviceps to permethrin, deltamerhrin, chlorpyrifos, malathion and chlordane was tested to estimate KT(50). The results showed that termite could be killed by these five insecticides respectively when the concentration range from 1ppm to 1000ppm. There was significant difference among the fice insecticides, the KT(50) of chlorpyrios and deltamethrin was less than chlordane.更多还原
