摘要: 利用雄性结扎不育方法研究雄性结扎不育对布氏田鼠交配行为和繁殖的影响。结果表明: 雄性结扎不育后不影响布氏田鼠雌雄两性的交配行为; 不育雄性的存在对雌性的正常交配产生了干扰, 降低了雌性的有效交配次数, 并导致雌性怀孕率和产仔数的下降。结果一方面说明结扎不育雄性方法可用于布氏田鼠的不育控制研究, 另一方面为不育后的竞争性繁殖干扰假设提供了实验证据。

Abstract: The influence of sterilized male on the copulatory behavior and reproduction of Brandt's vole was studied by using the method of surgical sterilization. It was showed no influence of male surgical sterilization on the copulatory behavior of Brandt's vole. Mating times with intact mates and litter size of female Brandt's voles in male sterilized groups decreased compared with the control groups. The results supported the hypothesis of competitively reproductive interference of sterilized male. Thus, sterilization can be a viable method to control voles.

Key words: Brandt's vole (Microtus brandti), Competitively reproductive interference, Male surgical sterilization
