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。 Objective To know more about the main rat species, seasonal variation and density distribution in Xiamen Port, and provide a scientific basis for better carrying out vector control in Xiamen Harbor. Methods According to “National vector bio-monitoring program (Trial)”, using the method of night clip, medium size rat clip was placed to produce peanuts and sweet potato for bait. Count the total number of mice, calculate the density of rats. Results From April to September in 2013, a total of 1 981 mousetraps were placed and 82 mouse-shaped animals were captured with a total capture rate of 4.14%. Two species of 2 orders and 2 families of rodent animals were captured, namely Rattus norvegicus, Rattus flavipectus and Rodentia spp. Rat-shaped stinkbugs were the dominant species, reaching 63, accounting for 76.8%. Conclusion In 2013, the population structure of Xiamen port was dominated by stinkbugs, and the rat density was the highest in August.
