摘　　要：2013年5-9月,在内蒙古锡林郭勒盟东乌珠穆沁旗草地研究贝奥不育剂、溴敌隆灭鼠剂对草原主要害鼠布氏田鼠的控制作用。通过早春一次性足量投饵(贝奥不育剂野外有效期30~60 d;溴敌隆灭鼠剂野外有效期30 d),按月铗捕调查的方法研究贝奥不育剂和溴敌隆杀鼠剂对该地布氏田鼠种群增长的控制效果。结果表明,5月不育剂组布氏田鼠的家系大小较杀鼠剂组的家系更大且差异显著(P<0.05),6月差异不显著,杀鼠剂组布氏田鼠种群恢复速度比不育剂组快。贝奥不育剂改变了布氏田鼠种群的性比,其幼体出生率比杀鼠剂组低。因此,贝奥不育剂对布氏田鼠有更好的防治效果。In order to study the control effect on population increases of Brandt＇s voles（ Lasiopodomys brandtii）,＂Beiao＂anti-procreate and poisoned baits（ Bromadiolone） were used in East Ujimqin Banner Grasslands,Inner Mongolia,with a one-time sufficient dose in spring from May to September in 2013. The tests were conducted in sterile experimental,lethal experimental and control areas. The Brandt＇s voles were captured by trapping monthly. Results showed that the voles＇ family group sizes were significantly different in the sterile and lethal experimental areas in May（ P〈0. 05）,but not in June（ P〈0. 05）. The Brandt＇s voles＇ population recovery rate was faster and the birth rate higher in the lethal area compared with the sterile area. The male ratio tendency varied in the sterile area where the ＂Beiao＂male anti-procreate was used. In summary,＂Beiao＂male anti-procreate demonstrates a better control effect on Brandt＇s voles.
