Abstract: Mandarin vole is one of the harmful rodents which lives underground in all it's life,in the dry farming area of loess plateau in Lingbao city,Henan province. The damage to crops was very serious.In the mature period of wheat,we surveyed the rate between the length of discontinuous plot of wheat and the total length of the plot of wheat.and surveyed the yield of wheat per unit area,and estimated the lossing of crops because of the damage of rodents. According to the level of economic losses,we got the threshold for mandarin vole to the field of wheat EIL=18.2 no./ha.According to the experiments on control of mandarin vole by several Rodenticides,Bromadiolone,Cumatetralyl, Phosacetin,Pyrinuron and Botulin model C to control mandarin vole we gained a good result.
