摘　　要：目的了解江苏省部分地区德国小蠊对溴氰菊酯、高效氯氰菊酯、敌敌畏、残杀威、乙酰甲胺磷5种常用杀虫剂的抗药性程度,以便通过抗性程度来指导科学、合理的用药。方法药膜接触法。结果江苏省4个地市的德国小蠊野外品系对上述5种杀虫剂的平均抗性系数分别为17.0、8.4、3.2、1.6和4.4。南京、南通、淮安品系对溴氰菊酯的抗性倍数最高,分别为22.9、20.6、16.1;丹阳品系对高效氯氰菊酯的抗性程度最高(R=10.9)。各品系德国小蠊对残杀威的抗性程度较低(R=1.6)。结论江苏地区4个野外品系德国小蠊对溴氰菊酯、高效氯氰菊酯、敌敌畏和乙酰甲胺磷均产生不同程度的抗性。Objective To estimate the susceptibility or resistance of Blattella germanica, including normal strain and four field-collected strain to dehamethrin, beta-cypermethrin, dichlorvos,propoxur and acephate in some areas in Jiangsu Province. Methods Contacting with chemical cover. Results The average resistance ratios of field-col- lected strains to dehamethrin, beta-cypermethrin, diehlorvos, propoxur and acephate were 17.0, 8.4, 3.2, 1.6 and 4.4 respectively. The resistance ratios of deltamethrin were high in Nanjing, Nantong and Huaian four field - collected strain（ R = 22.9, 20.6, 16.1 ）. The resistance also reached the high level to betacypermethrin in Danyang strain （ R = 10.9）. The average resistance ratios of field - collected strains to propoxur was low （ R = 1.6 ）. Conclusion Field collected strains of BlatteUa germanica in Jiangsu Province have already developed different resistance to four kinds of insecticides.
