The invention relates to an insecticidal composition containing 1-((6-chloropyridine-3-yl) methyl)-5-propoxy-7-methyl-8-nitryl-1,2,3,5,6,7-hexahydroimidazo[1,2-alpha] pyridine) and cypermethrin, and the insecticidal composition is highly effective for preventing animal pests. The insecticidal composition comprises the active ingredients the 1-((6-chloropyridine-3-yl) methyl)-5-propoxy-7-methyl-8-nitryl-1,2,3,5,6,7-hexahydroimidazo[1,2-alpha] pyridine) and the cypermethrin, wherein the weight ratio of the 1-((6-chloropyridine-3-yl) methyl)-5-propoxy-7-methyl-8-nitryl-1,2,3,5,6,7-hexahydroimidazo[1,2-alpha] pyridine) to the cypermethrin is (1:25)-(25:1), and the percentage composition of the 1-((6-chloropyridine-3-yl) methyl)-5-propoxy-7-methyl-8-nitryl-1,2,3,5,6,7-hexahydroimidazo[1,2-alpha] pyridine) and the cypermethrin in total is 1%-80%. According to the invention, the binary combination is performed on the 1-((6-chloropyridine-3-yl) methyl)-5-propoxy-7-methyl-8-nitryl-1,2,3,5,6,7-hexahydroimidazo[1,2-alpha] pyridine) and the cypermethrin so as to achieve a synergic effect on the insecticidal efficacy, the control effects on preventing lepidoptera, homoptera and arachnoidea pests on wheat, rice and vegetables are remarkable, and particularly, the insecticidal composition has remarkable effects on preventing froghoppers, leafhoppers, treehoppers, fulgoras, plant hoppers, phylloxeras, whiteflies, aphids, scale insects, cotton bollworms, leaf mites, thrips and stinkbugs.
