摘　　要：目的 :了解广东省德国小蠊对常用杀虫剂的抗药性 ,指导科学、合理使用杀虫剂。方法 :药膜接触法。结果 :野外采集 5个品系德国小蠊与敏感品系比较 ,对氯氰菊酯、溴氰菊酯的抗性系数分别为 1.99～ 2 0 .34、1.62～ 10 .2 8,对毒死蜱、残杀威的抗性系数分别为 0 .96～ 3.42、1.2 8～3.88。其中肇庆及茂名地区野外种群均对氯氰菊酯、溴氰菊酯产生了较高抗性。结论 :广东省德国小蠊对 4种杀虫剂的敏感性及抗药性不一 ,其化学防制须选择适当的杀虫剂。Five field collected strains of German cockroach, Blattella germanica , were tested for resistance to 4 different insecticides by the time mortality res ponse of single rate, continuous expoure methods in comparison with a known susceptible strain in Guangdong province. The results showed that five field collected strains were susceptible or low resistance to chlorpyrifos and propoxur, tow field collected strains were high resistance to cypermethrin and deltamethrin. The result indicated that cockroach control by chemical method should selected the suitable insecticide.
