Abstract: 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.
