【摘要】 目的了解清远市区蚊、蝇、蟑螂、鼠季节消长规律及种群构成,为制定防制对策,控制其危害提供科学依据。方法蚊密度监测用诱蚊笼法,蝇密度监测用诱蝇笼法,蟑螂密度监测用粘捕法,鼠密度监测用粉迹法。结果蚊、蝇密度高峰在第二季度,蟑螂密度高峰在第三季度,鼠密度全年平稳,无密度高峰;市区蚊以致倦库蚊为主,蝇以大头金蝇、家蝇为优势种群,蟑螂以美洲大蠊、德国小蠊为优势种群,鼠以褐家鼠、小家鼠为主。结论清远市区“四害”密度较高,防制应提倡综合治理方针策略与加强市民的公共卫生意识相结合。更多还原

【Abstract】 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.Americana and B.germanica were the advantage groups for cockroach population.Rattus norvegicus and Mus.musculus were the advantage group for mouse population.Conclusion The density of four pest was higher in Qingyuan downtown area in 2004～2005.The control and prevention should be promted to combine the strategy of integrated management with the public hygienic consciousness together.更多还原
