抗生育剂莪术醇对区域性害鼠的控制效应研究

2005～2006年,在山西隰县进行了0.2%莪术醇对区域性害鼠的防控效果试验。试验结果显示:(1)害鼠前三天对毒饵的平均摄食系数为0.47,大于0.3,接受性较好。(2)使用药剂后,雌体繁殖率降低了18.80%;平均胎仔数下降了7.5%,平均子宫斑下降了6.83%;亚成体所占的比率下降了72.28%,对害鼠的繁殖影响作用明显(。3)通过密度检测,试验药剂对种群密度的控制作用随着时间的推移效果在增加,第三次校正控制效果达到了44.73%,表明该药剂能够有效地降低害鼠的种群密度。(4)投药后,在试验区未发现天敌二次中毒及其他非靶动物出现异常现象,也未发生人、畜、禽误食中毒现象,大田使用安全。

Study on the Effect of Curcumol,One of sterilants,Control Territorial Rodents

The effect of 0.2 per cent of curcumol,one of the sterilants,controlled territorial rodents was tested in Xi County,Shanxi from 2005 to2006.The results showed:(1) The average food-intake coefficient of rodents eating poisoning bait was 0.47 three days in front,which was larger than 0.3.(2) The reproductive capacity of rodents obviously reduced after using poisoning bait: The rate of female procreation reduced 18.80%,the average litter size reduced 7.5%,the average uterus speckle reduced 6.83%,and the rate of non-adult rodents reduced 72.28%.(3) The rodent density was investigated.It showed as follow: The effect of poisoning bait controlled the rodent density enhanced along with the time processed.The rate of the third revised control effect reached 44.73%,which indicated that the rodent density could be effectively reduced by the sterilants.(4) Poisoning phenomenon of the non-aim animals,including the enemies of rodents,persons,domestic animals and poultries,did not happen in the experiment area after using poisoning bait.So using 0.2 per cent of curcumol in farmland was safe.
