Abstract:

Objective To provide scientific data for vector control after investigating its community structure and seasonal fluctuation in Ningbo, 2014. Methods Mouse trap, light trap, cage trap and glue trap were used to catch rodents, mosquitoes, flies and cockroaches respectively. Results The rodents were identified as 4 species of 3 genera, 1 family and Rattus norvegicus was predominant species and occupied 62.17%. The mosquitoes were identified as 4 species, 3 genera, 1 family and the dominant species, Culex pipiens pallens, occupied 61.54%. The flies belonged to 13 species of 7 genera, 3 families. Musca domestica was predominant species and occupied 24.10%. The cockroach were identified as 3 species of 2 genera, 1 family and Blattella germanica was predominant species and occupied 80.90%. Rodents and cockroaches were active throughout the year and active period was from April to October. Seasonality of mosquitoes and flies was obvious. The active peak of mosquitoes and flies were both on July. Conclusion The community structure and seasonal fluctuation of vector were preliminarily known. It should strengthen monitoring and control of vectors and vector borne diseases in Ningbo.
