目的掌握2006-2008年每年5-9月首都机场口岸地区鼠类种群构成变化及密度消长规律,为首都机场口岸鼠防工作提供依据。方法开展为期3年的奥运会病媒生物专项监测,并对监测资料进行汇总分析。结果2006-2008年5-9月首都机场口岸优势鼠种为小家鼠和褐家鼠,小家鼠常见于室外,褐家鼠常见于室内,黑线姬鼠构成比逐年下降。2006-2008年平均鼠密度分别为0.86%、0.29%和0.26%,呈逐年下降趋势。结论重大国际活动前,举办地国境口岸应实施专项鼠情监测,尤其是掌握重大建设工程对鼠种构成和鼠密度的影响,开展针对性的防治和投药灭鼠活动。
Objective To understand the changes of population structure and density of rodents during the period from May to September in Capital Airport from 2006 to 2008 so as to provide evidence for the prevention and control of rodents in Capital Airport Port. Methods To carry out 3-year special surveillance of vector in the Olympic Games and to collect and analyze the monitoring data. Results From May to September of 2006-2008, the dominant species in the port of Capital Airport were Mus musculus and Rattus norvegicus, while Mus musculus was common in the world. The composition ratio of Apodemus agrarius decreased year by year. The average rat densities in 2006-2008 were 0.86%, 0.29% and 0.26%, respectively, showing a declining trend year by year. Conclusions Prior to major international events, special rodent monitoring should be carried out at the border crossings in host cities. In particular, major impact of major construction projects on the composition of rodents and the density of rodents should be mastered. Targeted measures should be taken to prevent and control rodent infestation.
