Abstract: The paper reports the resistance of C.fatigans to several insecticides and control strategy in Nanchang area. The resistance of C.fatigans to deltamethrin, dichlorovos and trichlorphon had high levels, the resistance to acetophenate tended upwards obviously, ambrocide and fenitrothion were sensitive to C.fatigans. The resistance was closely related to the quantity and the frequency to be used of insecticide. There was not cross-resistance in fenitrothion and dichlorovos, trichlorophon, so it can be used instead of these insecticides that C.fatigans have developmented resistance to. Treatment measures of surroundings were suggested for eliminating mosquitoes. The major measure is to clean C.fatigans breeding place, the secondary method is to eliminate wigglers.
