The invention relates to a chalcone compound derived from Beta-ionone and a preparation method and an application thereof. The preparation method for the compound specifically comprises the followingsteps: in an organic solvent, and in the presence of a trapping agent, performing a condensation reaction on the Beta-ionone and substituted cinnamyl aldehyde, to obtain the compound. The provided chalcone compound derived from the Beta-ionone has apparent attractive activity of apolygus lucorum and insecticidal activity of plutella xylostella and tetranychus cinnabrinus, and has the direct control effect to the apolygus lucorum, the plutella xylostella and the tetranychus cinnabrinus. In addition, the preparation method is simple in process, easy to implement, less in by-product, higher in yield, and low in cost, and has a practical application value in agricultural production, and extensive application prospect.
