炔雌醚对内蒙古农牧交错带长爪沙鼠种群繁殖的影响
Effect of Quinestrol on the Reproduction of Meriones unguriculataus in the Farming-pastoral Transitional Zone of Inner Mongolia

中文摘要：炔雌醚对一些鼠类种群具有良好的控制效果。为探究炔雌醚对长爪沙鼠 Meriones unguriculataus种群繁殖的影响，于2006年5-8月在内蒙古锡林郭勒盟白音锡勒牧场农牧交错带展开了炔雌醚对长爪沙鼠野生种群繁殖的控制实验。设置了投药区和对照区，5月初进行投药，实验期间采用夹线调查法逐月对样地内的长爪沙鼠进行系统的取样调查，分析炔雌醚对长爪沙鼠种群繁殖的影响。结果显示：在投药之后的6-8月，投药区成体鼠的子宫坏死率分别为75.3%、61.5%和48.7%，与对照区差异有高度统计学意义（ P<0.01）；投药区成体鼠的怀孕率下降，与对照区差异有高度统计学意义（ P<0.01）；投药区的胎仔数显著低于对照区（ P<0.05）。综上表明，炔雌醚对农牧交错带长爪沙鼠种群繁殖的控制具有良好的效果。
英文摘要：Quinestrol is a kind of synthetic estrogen which has been used as contraceptive on some rodents. To study the effect of quinestrol on the reproduction ability of Mongolia gerbil ( Meriones unguriculataus), we conducted field experiments at farming-pastoral transitional zone in Baiyinxile, Inner Mongolia from May to August in 2006. The experimental area was divided into quinestrol baited area and control area. Standard snap-trap method was monthly used to capture the samples in both areas after spraying quinestrol bait in May. Subsequently, samples were dissected to examine the reproductive system and analyze the effect of quinestrol during June to August. The results showed that: (1) the rate of uterus necrosis in quinestrol baited area from June to August were 75.3%, 61.5% and 48.7%, respectively, and these were extreme significantly higher than the control area ( P<0.01); (2) the pregnant rate in quinestrol baited area was extreme significantly lower compared with the control area ( P<0.01); (3) the litter size in quinestrol baited area was significantly lower than the control area ( P<0.05). These results suggested that quinestrol had a significant suppression effects on the population reproductivity of M. unguriculataus. 2018,37(2): 207-210 收稿日期：2017-07-31 DOI：10.11984/j.issn.1000-7083.20170236 分类号：Q959.8 基金项目：国家自然科学基金项目（31560130） 作者简介：杨进荣(1990-),硕士研究生,研究方向:动物生态学,E-mail:love_jsu@163.com *通讯作者：刘志霄,E-mail:zxliu1965@163.com 参考文献： 阿娟, 付和平, 施大钊, 等. 2012.
