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 2 7.0mg m2氯菊酯时 ,对抗氯菊酯德国小蠊品系的KT50 为 47.2 1min ,48h死亡率为 64 % ;加入不同剂量的S2 和S1 后 ,KT50 分别为3 1.89～ 3 8.66min和 2 4.0 8～ 3 2 .47min ,增效倍数分别为 1.2 2～ 1.48倍和 1.45～ 1.96倍 ,48h死亡率均为 10 0 %。结论 :两种增效剂能提高氯菊酯的灭蜚蠊效果 ;S1 比S2Objective: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/m 2,KT 50 of permethrin-resistant German cockroach was 47.21 min and the death ratio was 64 percent in 48 h.When S 2 and S 1 were added in with different dosages, KT 50 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 S 1 is stronger than that of S 2.
