Abstract: 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.
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1.99~20.34、1.62~10.28,对毒死蜱、残杀威的抗性系数分别为0.96~3.42、1.28~3.88。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。
