| Abstract: | Objective To learn the resistance of Culex tritaeniorhynchus to insecticides in Xianyang City.Methods Media lethal dose method was used to detect the resistance of Culex tritaeniorhynchus to eight insecticides.Results The LC50 to DDT,DDVP,permethrin,cypermethrin,β-cypermethrin,deltamethrin,biothion,propoxur were 0.227,51.682,0.056,0.033,0.015,0.004,19.550,18.906 mg/L respectively.Compared with minimum value in previous data,resistant ratio was from 1.16 to 11.73.Conclusion The resistance of Culex tritaeniorhynchus in Xianyang city has developed in varying degrees.Breeding place should be administered first in controlling Culex tritaeniorhynchus.Mixed insecticide should be used in chemical control. |
