Abstract: Objective To improve original bait method,establish new bait-box method for monitoring rodent density,and primarily discuss the feasibility of the methods. Methods The quantity of bait eaten by rodents was observed. The masculine rate of bait-box and the bait's daily-losing-weight were tested in the area where the rodent density being in a high level. Results The masculine rate of bait-box and the bait's daily-losing-weight were linear interrelated. Two curves were fit logistic curve in density of rodent while the real density of rodent was relatively stable. They reach maximum and tend to be stable in 60th day. Conclusion This method is tend to monitor the density of rodent long at the same places.
