摘　　要：目的研究并掌握连云港市德国小蠊对常用杀虫剂的抗性情况,为合理使用杀虫剂提供科学依据。方法采用常用的药膜接触法,测定德国小蠊对高效氯氰菊酯、乙酰甲胺磷和残杀威抗药性。结果连云港市德国小蠊对高效氯氰菊酯、乙酰甲胺磷和残杀威的抗性系数分别为38.2、6.0和1.8,其抗性水平分别为高度抗性、中度抗性和低度抗性。结论连云港市德国小蠊对高效氯氰菊酯、乙酰甲胺磷抗和残杀威均产生不同程度的抗性,在防制蟑螂中,应根据抗性情况合理选择杀虫剂,以提高蟑螂的防制效果。Objective To study and understand the resistance to common insecticides of blattella germanica in Lianyungang, and provide scientific basis for rational use of insecticides. Method Use the common drug con- tacting method of drug sensitive layers to determiner the resistance to cypermethrin, acephate and propoxur of blattella germanica. Results The resistance coefficients of blatteUa germanica to cypermethrin, acephate and propoxur were 38.2, 6. 0, 1.8, and the resistance levels were high, moderate and low resistance, respective- ly. Conclusions Blattella germanica had different resistance to cypermethrin, acephate and propoxur. We should select appropriate insecticides to improve the control effect of cockroach according to their resistance to drugs.
