南昌口岸鼠、蝇、蚊及其携带病原体的调查

目的：为了摸清南昌口岸的鼠、蝇、蚊及其携带病原体的情况，对其进行了1年的本底调查。方法：用鼠夹及鼠笼捕鼠，粘蝇条诱捕法捕苍蝇，人工小时法捕蚊，浮选法收集鼠体的螨、蚤、蜱，分别用显微镜凝集试验、间接免疫荧光法检测钩端螺旋体及肾综合征出血热(HFRS)。结果：鼠类包括2目2科4属7种，以小家鼠、褐家鼠为优势鼠种，全年平均鼠密度为2．64％。鼠携带寄生虫(螨、蚤、蜱)的比例为37．50％，其中带螨率为27．50％，染蚤率为20．00％；带蜱率为7．50％。鼠肾钩端螺旋体检测为阴性。鼠血HFRS检测为阴性。蝇类有4科9属10种，以舍蝇、丝光绿蝇为优势蝇种，横带花蝇为该地首次报道。全年可监测到的蝇密度介于0．13—7．2只／(条．d)。蚊类有2亚科4属7种，淡色库蚊为优势蚊种。结论：加强灭鼠、灭蝇、灭蚊工作，有利于消除病媒动物及其携带病原体的危害。

Investigation of Mouse,Fly,Mosquito and Relative Pathogens at Nanchang Port

Objective In order to identify mouse,fly,mosquito and relative pathogens to provide basis for prevention,a baseline survey,from Dec.1999 to Nov.2000,was carried out at Nanchang Port. Methods Representative points for survey were selected. Mouse,fly,mosquito was captured respectively by double-layered mousetrap(mouse cage),flypaper,manpower hour method.Mite,flea and tick on mice were collected by flotation method.Leptospirosis and Haemorrhage Fever with Renal Syndrome (HFRS) of mice were tested respectively by microscope agglutinative test(MAT) and immunity fluorescent analysis (IFA). Results There were 7 rodent species,4 genera,2 families,2 orders at Nanchang Port.The dominant species were Mus musculus and R.norvegious.The annual average density of mouse was 2.64%.The carrying rate of parasites (mite,flea and tick) on rodent was 37.50%.The carrying rates of mite,flea,tick on rodent were 27.50%,20.00%,7.50% respectively.The tests of leptospirosis and HFRS of rodent were negative.There were 10 fly species,9 genera,4 families at Nanchang Port.Among them,M.domestica Vicina Macguart and Lucilia sericata Meigen were predominant species.Anthomyia illocata Walker was first reported in the district.The density of fly,which can be monitored this year,was 0.13-7.2 per strip for one day.There were 7 mosquito species,4 genera,2 subfamilies at Nanchang Port,the dominant species was Culex pipiens pallens Coquillett.Conclusion The effective control of rodent,fly,mosquito was benefit to wipe out the damage caused by mouse,fly,mosquito and relative pathogens.
