弓形夹捕杀长尾黄鼠的效果观察

Efficiency test of bow-shaped clamps in capturing Spermophilus ndulatus

目的了解和评价弓形夹现场捕获长尾黄鼠的效果和实用性,为今后灭鼠工作提供参考依据。方法 2018年5-7月在新疆维吾尔自治区乌苏市古尔图鼠疫监测点以大号板夹为对照,使用弓形夹采用夹日法进行长尾黄鼠捕获试验,χ^2检验比较不同方法的捕鼠率,t检验用于布设工效比较。结果弓形夹现场捕获长尾黄鼠时方位角比大号板夹增大l倍,平均捕鼠率高于大号板夹(χ^2=54.130,P=0.000),布夹工效是板夹的1.87倍。结论弓形夹具有捕鼠方位角广、防脱逃功能强和布放简单等优点,适宜在长尾黄鼠防治工作中大面积推广使用。

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, bowshaped 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 χ^2 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.
