摘要:

  【摘要】 目的 观察不同药剂对淡色库蚊的杀灭效果,为产品开发提供科学依据。 方法 气雾剂的室内药效测定和模拟现场药效测定。结果 室内药效测试KT50在1.30~4.40 min,24 h死亡率在95.0%~100%;模拟现场药效测试1 h击倒率和24 h死亡率均在93.0%~100%。7种杀虫气雾剂药效结果均符合国家标准,但彼此间存在较大差异。 结论 0.05%胺菊酯·氯氰菊酯杀虫效果最佳,具有击倒快,死亡率高,成本低的特点。

Abstract:

  【Abstract】 Objective To test the control efficacy of different chemicals to Culex pipiens pallens. Methods The methods of laboratory efficacy test for aerosol and simulated field efficacy test were used in this study. Results KT50 values of seven aerosols to Cx.pipiens pallens was 1.30-4.40 min, and the mortality rate was about 95.0%-100% after treatment for 24 h. The knockdown rate and the mortality rate were all within 93.0%-100% after treatment in the simulated field for 1h and 24 h. The control efficacy of seven chenmicals accorded with the national standards, but there was still more significant difference among them. Conclusion  The control efficacy of 0.05% tetramethrin·cypermethrin was the best, which had the characteristics of fast knockdown, high mortality and low cost.
