中文摘要	长爪沙鼠在内蒙古地区的分布非常广泛,长期以来由其造成的"鼠害"不仅给农牧业生产带来危害,而且还传播疾病。2009年3~10月,在内蒙古鄂尔多斯荒漠草原,利用复合不育剂左炔诺孕酮-炔雌醚(EP-1)对长爪沙鼠野生种群进行了不育控制试验研究。结果表明,复合不育剂EP-1对长爪沙鼠种群结构和种群密度均有显著影响,在5月和6月两个繁殖高峰期,不育剂EP-1显著降低了幼体出生的数量,实验区与对照区幼体组成差异和成体组成差异均达到极显著(P<0.01)。在8~10月,实验区和对照区种群结构组成中,幼体之间、成体之间差异均达到显著和极显著(P<0.05, P<0.01)。在整个发育生长期,实验区长爪沙鼠幼体种群从6月份开始出现,9月达到数量最高值,幼体种群全年呈现下降趋势。而对照区幼体种群从5月份开始出现,且数量在5月份达到全年的最高值,幼体种群与实验区相反呈增长趋势。实验区种群总体数量全年呈下降趋势,而对照区相反,呈增长趋势。因此,复合不育剂EP-1显著降低了长爪沙鼠种群的繁殖率、幼体出生比例和种群密度,可以对长爪沙鼠野生种群起到有效的繁殖控制作用,进而降低该鼠对农牧业生产的危害和对人类疾病传播的风险。
英文摘要	Mongolian gerbils(Meriones unguiculatus) are widely distributed in Inner Mongolia.This species not only has caused damage to grassland or crop production, but has also been a channel for transmitting human plagues in the above-mentioned region.From March to October in 2009, we used a contraceptive compound(EP-1) to test its fertility control effect on a wild population of Mongolian gerbils in the Ordos Desert Grasslands, Inner Mongolia.The results show that the breeding, structures and densities of Mongolian gerbil populations were significantly influenced by EP-1.During the first of the two peak breeding periods for gerbil populations, from May to June, juvenile recruitment significantly declined.The proportions of juveniles and of adults fluctuated significantly in the experiment and check areas(P<0.01).Similar fluctuations were seen in August to October in both areas(P<0.05, P<0.01).In the EP-1 treatment area, juvenile recruitment began in June, reached its peak in September, and their population density declined during the population growth period.In the control area, the juvenile recruitment peaked in May, and their population density showed an increase during the breeding period.In summary, reproduction, juvenile recruitment, the proportion of juveniles, and the population densities of Mongolia gerbils were significantly reduced during reproductive periods.These observations suggest that EP-1 is a very effective contraceptive for fertility control of this wild species, and may reduce the risk of damage to grass or crop production as well as the spreading of human plagues.
