The invention relates to a preparation method of a tung meal extract insecticide, which comprises the following steps that (1) tung meal is pulverized by a pulverizing machine after being dried, then the pulverized tung meal passes through a sieve with 50 or more meshes, the tung meal which passes through the sieve is heated and extracted for 2 to 4 times in a reflowing manner by ethanol with a volume fraction of 60 to 95 percent, and the extracted liquid is decompressed and distilled so as to recycle ethanol after being mixed, so that alcohol extract is obtained; (2) water is added to the alcohol extract and is uniformly mixed with the alcohol extract; (3) ethyl acetate is placed into the alcohol extract aqueous solution to be blended for 10 to 30 minutes, then the mixed solution is held and leached for 1 to 3 hours to be layered in a stationary way, and an upper layer of water phase is obtained to be decompressed and distilled so as to recycle the ethyl acetate, so that upper concentration liquid is obtained; and the leaching is repeated for 2 to 4 times, and the upper concentration liquid is decompressed and distilled so as to remove the residual ethyl acetate after being mixed, so that the tung meal extract, i.e. the tung meal extract insecticide is obtained. By utilizing the preparation method, the tung meal resource can be adequately developed and utilized, and the additional value of the tung meal can be improved by processing the tung meal into the plant insecticide.
