摘　　要：目的了解朝阳区不同区域德国小蠊对杀虫剂的抗性水平及分布情况。方法按行政区划选定8个取样点,采集每个取样点的德国小蠊自然种群,带回实验室繁育,用药膜接触法测定其对7种杀虫剂的抗性系数。比较德国小蠊对7种杀虫剂的抗性程度差别;比较8个取样点德国小蠊种群的抗性差别,并以类平均法做聚类分析。结果德国小蠊对7种杀虫剂的抗性程度差异具有统计学意义(χ2=26.880,P=0.000),对有机磷类杀虫剂的抗性最高(χ2=20.494,P=0.000);8个取样点德国小蠊种群对杀虫剂抗性水平差异亦有统计学意义(χ2=29.143,P=0.000),根据聚类分析结果和专业知识可将其划分为4类。结论朝阳区德国小蠊对杀虫剂存在地理位置差别,抗性监测和指导用药时"以点代面"做法不可取。Objective To know the resistance situation and its geographic distribution of German cockroaches （Blattella germanica） in Chaoyang district. Methods German cockroaches were trapped from eight sites belonging to different geographic zone. The insecticides film contact method was used to the detection of resistance. The resistance level of German cockroach from different sites was analyzed by average linkage method. Results There was significant difference among the resistance level of cockroach to seven insecticides （χ^2=26.880, P=0.000）. It had the highest resistance to organophosphorus insecticides （χ^2= 20.494, P=0.000）. The resistance levels of cockroach from 8 sites were also significantly different （χ^2=29.143, P=0.000）, which could be classified into four groups by cluster analysis. Conclusion The resistance of cockroach to insecticides was different in different areas in Chaoyang district, so the same control method.
