Abstract: Objective To provide scientific data for vector control after investigating its community structure and seasonal fluctuation in Wuhan,2006. Methods Mouse trap, light trap, cage trap and oach glue trap were used to catch rodents, mosquitoes, flies and cockroaches respectively. Results The rodents were identified as 3 species of 2 genera, 1 family andRattus norvegicus and R.flavipectus were dominant species and occupied 40.8% and 39.4% respectively. The mosquitoes were identified as 5 species, 4 genera, 1 family and the dominant species, Cluex pipiens quinquefasciatus, occupied 68.4%. The flies belonged to 5 species of 5 genera, 3 families. Musca domestica was dominant species and occupied 67.8%. The cockroach were identified as 3 species of 2 genera, 1 family and Blattella germanica was dominant species and occupied 89.8%. Rodents and cockcoaches were active throughout the year and seasonality was unconspicuous. Seasonality of mosquitoes and flies was obvious. The active peak of mosquitoes are on June while flies have two active peaks on May and November respectively of which the higher is on May. Conclusion The community structure and seasonal fluctuation of vector were preliminary known.
