摘  要:
The toxicity of several insecticides to first and fourth instar larvae in the laboratory,and the control effect of the nine insecticides to the fourth instar larvae of Bradysia odoriphaga Yang et Zhang in pots were tested respectively.The results demonstrated that chlorfluazuron,chlorpyrifos,phoxim and triazophos not only showed the higher toxicity in the laboratory,but also had good control efficiency in pots.The acting speed of chlorfluazuron was slow,and fourth instar larvae treated by it became deformed pupa when they pupated.Chinese chive maggot was not sensitive to cyromazine.Chlorfluazuron,chlorpyrifos,phoxim and triazophos had high efficiency to control Chinese chive maggot and low poisonous,so they can be applied in course of producing unpolluting vegetable.
