摘要:

  【摘要】 目的 了解张家港口岸鼠形动物种群分布和季节消长情况, 为防制提供科学依据。 方法  采用夹夜法。结果 采取综合防制措施后,张家港口岸的鼠密度一直处于较低水平。此次调查,鼠形动物4年的平均密度为0.10%,以小家鼠为优势种,占48.42%,其次为褐家鼠和麝鼩,分别占25.79%和24.43%。鼠密度于4、9月呈现两个高峰,其中2004年鼠密度分别为0.35%和0.31%;于12、1月和6、7月呈现两个低谷,约低于0.05%。食堂和防护带密度较高,达到0.13%,仓库最低,为0.03%。结论 张家港口岸鼠形动物以小家鼠为优势种,应在其繁殖高峰前后采取综合防制措施,降低鼠密度,预防传染病的发生。

Abstract:

  【Abstract】 Objective To grasp the population distribution and seasonal fluctuation of rat?shape animals at Zhangjiagang port,  and to provide the science evidence for its prevention and control. Methods Night?trapping method was used in this study.  Results The rodent density was in a low level after taking integrated measure. In this survey, the average density of rat?shape animals from 2004 to 2007 was 0.10%. Mus musculus was the dominant specie, accounting for 48.42%. Rattus norvegicus and Crocidura lasiura accounted for 25.79% and 24.43%. Two peaks of density appeared in April and September, which were 0.35% and 0.31% in 2004, and two troughs appeared in December?January and June July, about under 0.05%. The density in mess and fencing was 0.13% while the density of warehouse was 0.03%. Conclusion M.musculus was the dominant specie at Zhangjiagang port, and the integrate control measures should be taken to reduce density of rat?shape animals to prevent the occurrence of infectious disease.
