45%苯醚·硫酰氟熏蒸剂的药效试验研究

Biological efficacy of the 45% mixed fumigant of sulfuryl fluoride with d-Cyphenothrin

目的观察45%苯醚.硫酰氟熏蒸剂模拟现场熏蒸效果。方法参照《农药登记用卫生杀虫剂室内药效试验与评价第10部分:模拟现场(GB/T 13917.10-2009)》有关方法进行。结果 45%苯醚.硫酰氟熏蒸剂对蚊、蝇、蜚蠊、蠹虫等有害节肢动物最低试验致死剂量为5 g/m(3a.i.2.25 g/m3),对鼠类最低试验致死剂量为20 g/m(3a.i.9 g/m3)。结论 45%苯醚.硫酰氟熏蒸剂对蚊、蝇、蜚蠊、蠹虫等有害节肢动物和鼠类击倒快、杀灭效果优良。

Objective To observe the biological efficacy of the 45% mixed fumigant of sulfuryl fluoride with d-Cyphenothrin under simulated field.Methods The procedures described in the ＂Laboratory efficacy test methods and criterions of public health insecticides for pesticide registration＂of PRC criterion were referred to for the study.Results It was found that the lowest lethal dose of the mixed fumigant to mosquito,fly,cockroach and clothes moth,etc.was 5 g/m3（a.i.2.25 g/m3）,with the dose to mice being 20 g/m3（a.i.9 g/m3）.Conclusion The 45%mixed fumigant of sulfuryl fluoride with d-Cyphenothrin has a quick knock-down and excellent lethal effect on both pests and mice.
