摘要: 目的:了解氯菊酯与增效剂的复配对德国小蠊的毒效。方法:果酱瓶药膜法。结果:当使用27.0mg/m2氯菊酯时,对抗氯菊酯德国小蠊品系的KT50为47.21min,48h死亡率为64%;加入不同剂量的S2和S1后,KT50分别为31.89~38.66min和24.08~32.47min,增效倍数分别为1.22~1.48倍和1.45~1.96倍,48h死亡率均为100%。结论:两种增效剂能提高氯菊酯的灭蜚蠊效果;S1比S2对氯菊酯的增效作用强。

Abstract: Objective:To survey the effect of compound of permethrin and synergist against German cockroach.Methods:The method of contacting with chemical cover in jar was used in this study.Results:When the concentration of permethrin was 27.0 mg/m2,KT50of permethrin-resistant German cockroach was 47.21 min and the death ratio was 64 percent in 48 h.When S2 and S1were added in with different dosages,KT50 were 31.89-38.66 min and 24.08-32.47 min respectively.The increasing multiple were 1.22-1.48 and 1.45-1.96 respectively,and the death ratio were all 100 percent.Conclusion:Two kinds of synergists can increase the effect of permethrin against cockroach,and the synergism of S1 is stronger than that of S2.
