[目的 ]为防鼠灭鼠工作提供科学依据。 [方法 ]于 2 0 0 0年 5月～ 2 0 0 1年 4月对外轮开放后的东山口岸外环境和居民区室内 ,采用 EL T10 N夹夜法和笼捕法 ,逐月定期进行鼠形动物及寄生蚤调查。 [结果 ]全年共捕获鼠形动物 2 75只 ,隶属 2目 2科 4种 ,即褐家鼠、黄胸鼠、小家鼠和鼠句鼠青。居民区室内平均鼠密度为 10 .4% ,繁殖指数 5 3.8% ,繁殖高峰在8月和 9月 ,以褐家鼠为优势鼠种占 6 5 .9%。发现两种寄生蚤 ,蚤指数 0 .5 1,染蚤率 16 .5 %。 [结论 ]东山口岸鼠患是严重的。应经常开展口岸灭鼠灭蚤 ,以褐家鼠为主要防制对象 ,在繁殖高峰前进行 [Objective] To provide a scientific basis for anti-rodent control work. [Method] From May 2000 to April 2001, the external environment of Dongshan Port and the residential area of ​​Dongshan Port after the opening of the Outer Ring were opened with EL T10 N - clamp method and cage catching method. Rats Shaped animal and parasitic fleas investigation. [Result] A total of 2 75 rat-shaped animals were captured in the year, belonging to 2 orders, 2 families and 4 species, namely Rattus norvegicus, Rattus flavipectus, Mus musculus and Rodent. The mean indoor rat density in residential areas was 10.4%, the reproductive index was 3.8%, and the breeding peak was in August and September. The dominant species was Rattus norvegicus, accounting for 65.5%. Two parasitic fleas were found, with a flea index of 0.51 and a flea flea rate of 16.5%. [Conclusion] The rats in Dongshan Port are serious. Port rodent and flea should be frequently carried out, with Rattus norvegicus as the main control target, before breeding peak
