Objective To investigate the growth and decay trend and population composing of mosquito, fly, cockroach and mouse, and to provide science foundation for establishing control and prevention measures and controlling its harm. Methods Using mosquito-trap method for monitoring mosquito density, using fly-trap method for monitoring fly density, using glue method for monitoring cockroach density and using flour-board method for monitoring mouse density. Results The density peak of mosquitoes and flies were the second quarter. The density peak of cockroaches was the third quarter. There were no density peak of mouse , Culex pipiens quinquefasiatus was the main group for mosquito population. Chrysomya megacephala, Musca domestica were the advantage groups for fly population. P.
