| Abstract: | Objective To investigate the resistance of Culex pipiens quinquefasiatus to six differ ent kinds of insecticides and make corresponding control statics. Meth ods Soaking test-larva soaking in insecticide solution (recommended by WHO) was used in the experiment to test medium lethal concentration of the larva of the fourth instar. Results The resistance times of Culex pipiens quinquefasiatus to s ix kinds of commercial insecticides, Dic hlorphos, Bassa, Acetofenate, Permethr in, Deltamethrin, high effect cypermethrin in different city on spot test were s howed as following:3.58, 2.78, 1.20, 4.43, 7.58,2.24.Conclusion The present experiment showed that the Culex pipie ns quinquefasiatus had resistance to six different kinds of insecticides, and especially had more resistance to Permethrin and Deltamethrin. |
