Abstract: Objective To understand vector species and seasonal fluctuations in Jiading district, providing the evidence for the prevention and control of vector-borne diseases. Methods The surveillance sites were set up according to the national vector surveillance project. The densities of vectors like rodents, flies, mosquitoes and cockroaches were investigated by the methods of night trapping, cage trapping, light trapping and paste trapping, respectively. Results The rodents in the district were identified to be of 3 species, 2 genus, 1 family, with Mus musculus (69.23％ ) being the dominant species followed by Rattus norvegicus (21.15％). The peak density of rodents was seen in September. There were 4 species, 4 genus and 3 family of flies in the district, with Musca domestica being the dominant species, accounting for 68.49％ . July saw the peak density of flies. There were 3 species, 2 genus and 2 families of mosquitoes in this district. Of which Culex pipiens pallens was dominant, accounting for 73.83％, followed by Cx. tritaeniorhynchus (12.58％) and Anopheles sinensis (13.59％). The density of mosquitoes peaked in August. The cockroaches collected in the district belonged to 2 species, 2 genus and 2 families. The dominant species was Blattella germanica (89.29％), its peak density seen in July. Conclusion M. musculus, M. domestica, Cx. pipiens pallens and B. germanica are the dominant species of the vectors. The peak density of rodents is seen in September and that of other vectors in July.
