The invention relates to a spreading oil for controlling Lissorhoptrus oryzophilus Kuschel. A technical scheme adopted in the invention is characterized in that the spreading oil comprises 10-60wt% of an effective component, 3-80wt% of an assistant, 0-70wt% of a filler, 5-10wt% of a water surface dispersing agent and 0-10wt% of water, wherein the effective component comprises one or two of chlopyrifos, diazinon, dichlorvos, imidacloprid, thiamethoxam, clothianidin, thiacloprid, thiazoline, nitenpyram, dinotefuran, pymetrozine, isoprocarb, fenobucarb, MTMC, dimethacarb, ethofenprox, carbosulfan, sulfoxaflor and flonicamid, and the weight ratio of the above any two is (1:10)-(10:1) when the effective component combines the above two. The spreading oil has the advantages of simple operation during drug application, labor and time saving, improvement of the utilization rate of the effective component and the control effect on the Lissorhoptrus oryzophilus Kuschel, no harms to human bodies, labor intensity reduction, manpower saving, and saving of the agricultural production cost.
