Abstract: Objective　To study the control effects of triptolide baits and curcumol baits on Spermophilus dauricus, and to provide a scientific basis for the control of S. dauricus in the prairie region. Methods　Field investigation was extensively performed, in which rodent density, the rate of testis descending among male rodents, the pregnancy rate among female rodents, and the number of fetuses were compared between experimental area and control area, to evaluate the control effects of triptolide baits and curcumol baits on S. dauricus. Results　In the experimental area for triptolide baits, the population density of S. dauricus, the rate of testis descending among male rodents, the pregnancy rate among female rodents, and the average number of fetuses declined 23.62%, 62.50%, 71.32%, and 44.62%, respectively. In the experiment area for curcumol baits, the rate of testis descending among male rodents, the pregnancy rate among female rodents, and the average number of fetuses declined 25.00%, 73.78%, and 32.75%, respectively. Conclusion　The triptolide baits show excellent killing and anti-fertility effects in the control of S. dauricus, while the curcumol baits show anti-fertility effect.

摘要： 目的　研究雷公藤甲素饵剂和莪术醇饵剂对达乌尔黄鼠的防治效果,为草原黄鼠防治工作提供科学依据。方法　采用现场试验,对比观察试验区与对照区鼠密度、雄鼠睾丸下降情况、雌鼠怀胎率、胎鼠数指标差异,判断雷公藤甲素饵剂和莪术醇饵剂的防治效果。结果　雷公藤甲素饵剂试验区鼠密度下降了 23.62%,雄鼠睾丸下降率降低了62.50%,雌体怀胎下降率为71.32%,平均胎仔数下降率为44.62%;莪术醇饵剂试验区雄鼠睾丸下降率为25.00%,雌体怀胎下降率为73.78%,平均胎仔数下降率为32.75%。结论　雷公藤甲素制剂对达乌尔黄鼠具有较好的杀灭作用和抗生育作用;莪术醇饵剂对达乌尔黄鼠具有抗生育作用。
