The invention belongs to the field of chemical ecology of agricultural pests and pesticide science, and relates to an insecticide composition for improving the sensitivity of agricultural pests to insecticides and application of the insecticide composition. Folic acid is applied to a pest feeding substrate, a host plant or a feed, so that the sensitivity of pests to various insecticides (including neonicotinoids, pyrimidines, pyrethroids, organophosphorus and the like) can be remarkably enhanced. It is found that folic acid can regulate and control a carbon metabolism network in pests and inhibit cytochrome P450 and other detoxification enzyme related pathways, and then the endurance capacity of the pests to insecticides is reduced. The composition and the method are verified in seven important pests such as brown planthopper, sogatella furcifera, spodoptera frugiperda, cotton aphid, chilo suppressalis, panonychus citri and thrips, have the advantages of improving the pesticide effect, reducing the pesticide application amount and delaying the resistance evolution, and can be widely applied to comprehensive treatment of agricultural pests.
