The invention relates to a synergistic pesticide composition containing chlorfenapyr fluorobenzamide bisamide and neonicotinoid insecticide. The active ingredient is a binary compound of the chlorfenapyr fluorobenzene bisamide and the neonicotinoid insecticide. The mass ratio of the chlorfenapyr fluorobenzene bisamide to the neonicotinoid insecticide is 1:50-50:1, the mass ratio of the active ingredient chlorfenapyr fluorobenzene bisamide to the flunicarbamide is 1%-80%, and the rest is an auxiliary component; the dosage form of an insecticidal composition is a water-dispersible granule, wettable powder, a suspending agent, an emulsifiable concentrate, a microemulsion or an an aqueous emulsion, and the composition is mainly used for controlling hemiptera, lepidoptera and coleoptera such ashibiscus, planthopper, whiteflies, spider mites, mites, blind mites, scale insects, mites, cotton bollworm, diamondback moth, grass worms, leaf roller moths, heartworm, potato beetles and the like. The composition expands the insecticidal spectrum of a single agent, and has a significant synergistic effect, and the insecticidal activity is obviously enhanced than the single agent, which reduces the dosage of a pesticide and reduces the environmental pollution.
