目的观察2种不同的氯菊酯复配剂对淡色库蚊、德国小蠊、家蝇的杀灭效果。方法按照国标GB/T13917.1-2009中喷雾及滞留喷洒方法和GB/T13917.10-2009模拟现场药效测定方法进行。结果 2种复配剂对淡色库蚊、德国小蠊、家蝇的喷雾和模拟现场效果24 h内死亡率均为100%,在不吸收、半吸收、吸收表面30、45 d平均死亡率大于90%,符合GB/T13917.1-2009的A级要求。结论 2种不同的氯菊酯复配剂快速杀灭率高,在不吸收、半吸收、吸收表面对蚊、蝇、蟑有较好的杀灭效果,施药后表面药痕小、有较长的持效性,药效稳定。
Objective To observe the killing effects of two different permethrin compounds against Culex pipiens pallens, German cockroaches and house flies. Methods according to the national standard GB / T13917.1-2009 spraying and retention spraying method and GB / T13917.10-2009 simulated field efficacy measurement method. Results The results showed that the mortality of all the two compounds against Culex pipiens pallens, German cockroaches and houseflies was 100% within 24 h, and the mean death rates at 30 and 45 days after absorption were not greater than 90%, in line with GB / T13917.1-2009 Class A requirements. Conclusion The two different permethrin compounds have a high rate of killing rapidly, and have good killing effect on mosquitoes, flies and cockroaches on non-absorbed, semi-absorbed and absorbed surfaces. Long-lasting, stable efficacy.
