Induction of high effect cypermethrin on glutathione peroxidase of blattella germanica

  Objective   To research the effects of high effect cypermethrin on glutathione peroxidase(GPX)of blattella germanica so as to search for the operational mechanism of high effect cypermethrin and provide theoretical basis and useful methods.

  Methods   Quantitative high effect cypermethrin of different concentration was sprayed upon the method of GB 13917.1-13917.8-92 for insecticide registered testing indoor effect. The activities of SOD were determined by using Glutathione peroxidase (GPX)Kit.

  Results   The inductive time effect of high effect cypermethrin of different concentration was different, for some degree, the correlation of the inductive intensition and the concentration of high effect cypermethrin was positive relationship.

  Conclusion   GPX can be appearly induced by high effect cypermethrin. The increase of GPX activities in blattella germanica was relative with pesticide tolerance to pyrethroid insecticides.
