深圳皇岗口岸医学媒介生物监测与控制

Monitoring and Control of Vector at Huanggang Port

目的掌握皇岗口岸鼠类、蚊类的本底情况,为制定有效的防治措施提供依据。方法2006年12月～2007年11月采用鼠笼法对皇岗口岸的鼠类进行了调查,采用灯诱法进行蚊类调查。结果共捕鼠104只,经鉴定为2目2科3属4种。褐家鼠为优势种,年平均密度为8.78%。捕蚊249只,经鉴定为1亚科2属3科。蚊类平均密度为0.56只/小时*灯,其中致倦库蚊为优势种。结论皇岗口岸鼠密度超过国家标准要求,应尽快采取措施加强灭鼠工作,减低鼠害发生的风险。成蚊密度符合国家标准要求。继续开展口岸生物媒介本底调查,掌握其变化规律,有针对性的开展灭鼠、灭蚊工作。

Objective Provide foundation for the development of effective measures of prevention and control according to the background of rat and mosquito in Huanggang port. Methods： Rat-cage and ultraviolet lamp trap are employed in investigations in Huanggang port from Dec.2006 to Nov. 2007. Result 104 rodents captured were identified belong to 2 orders ,2 families,3 genera, 4 species among which Rattus norvegicus Berkenheut was dominant species with annual average density reached 8.78%. 249 mosquitoes captured were identified belong to 1 subfamily, 2 genera, 3 families with average density was 0.56 flies/hour^＊lamp among which Cx pipiens quinquefasciatus was dominant species. Conclusion As the density of rats in Huanggang Port surpasses national standard, measures shall be taken as soon as possible to strengthen rat destruction work, decrease the risk of pestilence and make the mosquito density conform with national standards. We shall also continue to carry out border vector background investigation in order to grasp the regularity for change and conduct pointed rat and mosquito destruction work.
