The invention relates to the technical field of organic synthesis and particularly discloses a novel method for preparing an arylpyrazole mono or poly alkylated derivative through integration of ultrasonic wave atomization and microwave radiation. The reference literature of synthesis of the arylpyrazole mono or poly alkylated derivative is few, and generally a heating reflux preparation method is adopted. Because heating reflux method operation and post-processing are tedious, solvent evaporation causes environment pollution, and the yield is low. The ultrasonic wave atomization and microwave radiation method is used, so that the operation is simple and safe, the yield is high, the time is short, energy conservation and environment protection are realized, the reaction condition is mild, and the operation is simple and convenient, clean and free of pollution. The prepared product is used for preparing suspending agents and can prevent and cure orthoptera, thysanoptera, homoptera, heteroptera, coleoptera, hymenoptera, diptera and mite pests.
