The invention discloses a novel method for treating small brown rice planthopper which carries virus. The essence of the invention leads the moving ability of the small brown rice planthopper to drop temporarily by adopting a refrigeration method so as to start the operation of quantitative capturing. With the recovery of body temperature, the abilities of moving, feeding and virus transmitting of small brown rice planthopper are recovered again; therefore, the purpose for moving small brown rice planthopper rapidly and quantitatively can be achieved. Compared with the original method, the method of the invention is characterized by being more convenient and rapid and is applied to inoculation identification of small brown rice planthopper which transmits virus diseases such as stripe virus of rice, etc.
