1984-2009年贵州关岭县鼠类种群及其变化规律

为摸清贵州省关岭县鼠种种类及优势种,研究鼠类种群数量变化规律,为大面积灭鼠工作提供科学依据,对贵州省关岭县1984-2009年住宅、稻田和旱地3种生境类型的鼠情调查结果进行了分析。结果表明:关岭县家栖鼠类和农田鼠类主要有7种,黄胸鼠、褐家鼠均为住宅区和农田、旱地耕作区害鼠优势种,分别占总鼠量的67.15%、31.86%和62.78%、26.11%,合计占总鼠数的99.01%和88.89%,是监测和防治的主要对象。住宅区混合鼠种多年平均捕获率为12.70%,明显高于稻田、旱地耕作区平均捕获率2.76%。住宅区混合鼠种每年在5-7月出现1个种群数量高峰,多年平均捕获率均达13%以上,农田区混合鼠种每年在4-9月出现1个种群数量高峰,多年平均捕获率均达3%以上,每年4-5月为防治的关键时期。
