Abstract: Objective To learn vector species and its seasonal fluctuation in the Qingpu district,and to provide the evidence for the prevention and control of vector-borne diseases.Methods The surveillance sites were set up according to the surveillance project of the vector in the whole country,and the densities of vectors like mosquito,fly,mouse and cockroach were investigated by the methods of man-hours,cage trapping,paste trapping and night trapping,respectively.Results There were 8 species,4 genus and 2 subfamily mosquitoes in this district.Of which,Culex pipiens pallens was the dominant specie,accounting for 63.04%,following with Armigeres subalbatus(18.72%) and Anopheles sinensis(6.45%).The density of mosquitoes was in the peak in July.There were 35 species,20 genus and 3 family flies in the district,and Musca domestica,Chrysomya megacephala and Lucilia sericata were the dominant species,which accounted for 36.11%,24.42% and 8.39% respectively.There were two peaks in the whole year,the biggest one was in August and the second one was in October.The cockroaches investigated in the district belonged to 3 species,2 genus and 2 families.The dominant species was Blattella germanica(78.60%),following with Periplaneta fuliginosa(13.38%) and Periplaneta americana(8.02%),and its density peak was in July.The rat-shape animals were identified in the district belonging to 5 species,3 genus,2 families and 2 orders.The dominant species were Mus musculus(67.74%) and Rattus norvegicus(20.10%),respectively.The peak of rodent density was in June.Conclusion No new vector species were found in this district.
