The invention relates to an insecticidal combination containing pymetrozine. Imicyafos and the pymetrozine which serve as effective components are mixed; the weight ratio of the two effective components is (1-50):(55-1), and preferably the weight ratio is (5-25):(35-5). The insecticidal combination comprises 1-80 percent of the effective components by weight, preferably 5-40 percent of the effective components, and the balance being pesticidally available and acceptable auxiliary components. Wettable powder, a suspending agent, a microemulsion, an emulsion in water and a water dispersible granule can be prepared by a known method. The combination disclosed by the invention has a wide acting field and is high in insecticide efficiency; furthermore, the using amount is small; the prevention efficiency is high; the residue content is low; the lasting period is long; the environment can be protected favorably.
