目的研究大面积应用雷公藤制剂和莪术醇制剂控制达乌尔黄鼠的使用方法,为草原黄鼠防治工作提供科学依据。方法采用毒饵撒播机方法进行投药,对比观察鼠密度,雄鼠睾丸下降率、雌鼠怀胎率、胎鼠数等指标差异,判断不育剂防治黄鼠的效果。结果毒饵撒播法施用雷公藤制剂控制达乌尔黄鼠密度达到0.14只/hm~2,较对照比较下降0.96只/hm~2。雄鼠睾丸下降率降低46.1%,雌鼠怀胎率下降39.18%;莪术醇制剂雌鼠怀胎下降47.6%。结论雷公藤制剂和莪术醇制剂可用于草原大面积黄鼠不育控制工作。
Objective To study the application of Tripterygium wilfordii and Curcuma longa preparations to control Daurian ground squirrels over a large area and provide a scientific basis for prevention and control of grass carp. Methods The drug was administered by using the bait disperser method. The differences of rat density, the rate of testicular descent in male rats, the pregnancy rate of females and the number of fetal rats were observed and compared. Results The results showed that the density of Daurian ground squirrel reached 0.14 / hm ~ 2 with the control of Tripterygium wilfordii, and decreased 0.96 / hm ~ 2 compared with the control. The rate of testicular descent in male rats decreased by 46.1%, that of female rats decreased by 39.18%, that of female rats in curcumol decreased by 47.6%. Conclusion Tripterygium preparations and Curcuma alcohol preparations can be used for the control of large-scale gonads infertility in grasslands.
