摘　　要：目的验证鼠用0．2％莪术醇饵剂控制害鼠的抗生育效果和使用安全性。方法在云南省大理州鹤庆县农田开展鼠害控制示范试验，每公顷投药量为4．5—6kg，药后1个月用鼠夹夹夜法，调查害鼠种类、数量（此后每隔1个月调查1次，共调查4次），对捕获鼠进行分类鉴定后，解剖雌鼠，观察怀孕状况；雄鼠观察睾丸是否下降，根据害鼠上臼齿磨损状况，记录害鼠年龄组成情况，计算捕获率及控制效果。结果参与繁殖的害鼠在逐步下降，怀胎率、胎子数降低，害鼠种群逐步趋向老年化；对种群密度的控制作用随着时间的推移效果在增加；未发现天敌及非靶动物、人、畜、禽出现异常现象。结论该药剂使用安全，抗生育效果显著，对农田鼠害控制效果明显。Objective In order to verify the sterilizing effect and safety of 0.2% curcumol bait. Methods 0.2% curcumol bait were applied at the dosage of 4.5 - 6 kg/hm2 in the rodent control experiment farmland in Heqing coun- ty, Dali municipality, Yunnan Province. One month after the application, the species and number of rodents were inves- tigated with night trapping method. After that,the investigation was made every one month for 4 times. After classify and identify the captured mice, female rats were dissected to observe the pregnant indexes, and male rats were dissec- ted to observe the testicle. Then records the age composition of rats by observes the wear condition of its upper molars. Finally calculate capture rate and control effect. Results The results showed the female pregnancy rate and litter size decreased and the proportion of sub-aduhs reduced, rodent populations gradually tend to aging. The control effect on population density increased with the time. No abnormal phenomena were found in the natural enemies, human beings, livestocks,poultry and other non-target animals. Conclusion The bait was safe in application and had obvious effect in sterilization and control of rodent pest in the farmland.
