Population Dynamic and Reproductive Characteristic of Rattus rattoides in Yunxiao County

摘要: 2002-2011年云霄农田鼠情系统监测结果表明, 黄毛鼠是云霄县农田优势种, 占84.5%, 其种群消长动态呈现明显季节性波动, 月平均捕获率为5.4%9.2%, 年内出现2次高峰, 除个别年份外, 年度间种群消长动态较为平稳。调查数据显示, 黄毛鼠雌雄总性比为1.5∶1, 每年的112月份均能捕到怀孕鼠, 不存在12、1、2月为偶然繁殖期, 平均月怀孕率为45.9%, 繁殖指数为160.6%, 说明黄毛鼠在云霄乃至闽南农区具有较强繁殖能力, 成为影响农田黄毛鼠种群数量变动的主要因子。笔者根据黄毛鼠种群消长规律分析, 提出了可持续防控农田鼠害的策略, 为农田科学灭鼠提供参考。Abstract: Systematic monitoring results of rat situation in Yunxiao County (Fujian Province) from 2002 to 2011showed that Rattus rattoides is a dominant specie in residential areas, accounting for 84.5%.There is obvious seasonal fluctuation, monthly average catch rate (5.4%-9.2%) , two peak of catch rate in a year, though the population dynamics is stable relatively.Normally, the sex ratio (♀/♂) of Rattus rattoides was 1.5:1and the Pregnant rats was found in a year.Meantime, the monthly pregnant rate, reproductive index were 45.9%, 160.6%, suggesting that Rattus rattoides has a greater reproductive capacity.Our results will put forward to the sustainable control strategy of farmland rodent and provides the reference for scientific deratization.
