Abstract:
Objective To more perfectly undestand the operational mechanisms of high effect cyper methrin by researching the dosage effect and the time effect between high effect cypermethr in and Ca-ATPase activities of Blattella germanica.
Methods Quantitative high effect cypermethr in of different concentration was sprayed upon the method of GB 13917.1-13917.8-92 for insecticide registered testing indoo reffect.The activities of Ca-ATPase were determined by using ATPase Kit.
Results Inhibition of high effect cyper methrin on Ca-ATPase activities of Blattella germanica showed concentration gradient effectin 48 hours.The results showed the correlation of concentration of high effect cypermethr in and inhibiting time effect on Ca-ATPase activities of Blattella germanica in 144 hours and death rate of Blattella germanica in 72 hours was positive relationship.
Conclusion Ca-ATPase is one of the targets of high effect cypermethrin.Because of sensitivity decrease of Na-K-ATPase, tar get resistance may be one of the important resistant mechanisms to high effect cypermethrin.
