Composite insecticidal composition containing pyridalyl and fufenozide and application thereof

The invention discloses a composite insecticidal composition containing pyridalyl and fufenozide and an application thereof. According to the insecticidal composition, pyridalyl and fufenozide are used as insecticidal active ingredients, wherein weight ratio of pyridalyl to fufenozide is 1-100: 1-100. By the use of the insecticidal composition, high synergistic effects can be generated, pest resistance to insecticide is overcome and delayed, insecticidal speed is fast, persistent period is long, medication cost is reduced, and control effect of the insecticidal composition is obviously better than that of a single reagent. The insecticidal composition can be used in controlling lepidoptera pests on crops, especially cotton bollworm and stem borers, and effects of the insecticidal composition are obviously better than effects of a single reagent.
