Abstract: Objective To investigate the efficiency and practicability of bow-shaped clamps in field control of Spermophilus undulatus, and to provide a reference basis for deratization in future. Methods With the large-size clips as a control, bow-shaped clamps and the trap-day method were used to capture S. undulatus in Guertu plague surveillance sites in Wusu county of Xinjiang Uygur Autonomous Region from May to July, 2018. The χ² test and t test were used to compare the capture rate and installation efficiency of different methods. Results The azimuth angle of bow-shaped clamps was one time larger than that of the large-size clips. The mean capture rate of bow-shaped clamps was higher than that of the large-size clips (P=0.000), and the installation efficiency of bow-shaped clamps was two times than that of the large-size clips. Conclusion Bow-shaped clamps have the features of large azimuth angle, strong anti-escape function, simple installation, and no need for baits. Therefore, they can be used to control S. undulatus.
