摘要
目的了解海淀区现场品系德国小蠊对常用杀虫剂的抗性水平,为合理选择用药提供依据。方法采用药膜接触法测定抗性水平。结果现场品系德国小蠊对氯氰菊酯、溴氰菊酯、残杀威、乙酰甲胺磷和敌敌畏的抗性系数分别为7.033、.202、.907、.57和>13.13。结论海淀区德国小蠊对残杀威没有产生明显的抗药性,对溴氰菊酯产生了耐药性,而对氯氰菊酯、乙酰甲胺磷和敌敌畏产生了明显的抗药性。
Objective To determine the resistance of Blattella germanica to five commonly used insecticides in Haidian district and provide the evidence for rational insecticides selection.Methods The resistance was examined by the method of contacting with chemical cover.Results The resistance index of field collected strains to cypermethrin,deltamethrin,propoxur,acephate and dichlorvos were 7.03,3.20,2.90,7.57 and 13.13 respectively.Conclusion The field strain in Haidian district has no significant resistance to propoxur.However,it has developed low resistance to deltamethrin and high resistance to cypermethrin,acephate and dichlorvos.
