| Abstract: | Objective To investigate the resistance of housefly to 5 kinds of normal used insecticides in Dalian and compare with the results of 2001 and 2006.Methods The trace drop method was used.Results The LD50 of housefly to beta-cypermethrin,deltamethrin,DDVP,chlorpyrifos and proposur were 0.146 4、0.030 1、0.452 3、0.607 2、﹥97.27 respectively.The resistance ratio were 52.29,50.17,39.68,20.17 and 335.41 respectively.Conclusion Housefly has developed high resistance to 5 kinds of normal used insecticides in Dalian.It is necessary to strengthen monitoring of resistance and use insecticides scientifically.Integrated management should be taken to overcome or delay the resistance development of housefly. |
