2013年厦门港区鼠类监测分析

Surveillance of rodents at Xiamen port in 2013

目的为进一步了解厦门港区的主要鼠种、季节消长规律及其密度分布,为更好开展厦门港区病媒生物防治工作提供科学依据。方法遵照《全国病媒生物监测方案(试行)》,采用夹夜法,布放中号鼠夹,以生花生米、地瓜为诱饵,晚放晨收,连续3 d。统计捕鼠总数,计算鼠密度。结果 2013年4-9月共布放有效鼠夹1 981个次,共捕获鼠形动物82只,总捕获率为4.14%。捕获鼠形动物2目2科3种,即啮齿目鼠科属的褐家鼠、黄胸鼠和食虫目鼠鼩鼱属的臭鼩鼱。鼠形动物以臭鼩鼱为优势种,达63只,占76.8%。结论 2013年厦门港区鼠种群结构以臭鼩鼱为优势种,鼠密度8月份最高。
