2008-2009年柳州市蚊蝇密度监测分析

Monitoring and analysis the density of mosquitoes and flies in Liuzhou during 2008 to 2009

目的了解柳州市城区蚊、蝇类季节消长规律及种群构成,为制订防制对策提供科学依据。方法蚊密度监测用人工小时法,蝇密度监测用诱蝇笼法。结果蚊在第二、四季度出现密度高峰,致倦库蚊为优势种群;蝇类密度2008年分别在2、7月出现高峰,2009年则在4、6、8、9月出现高峰,以丝光绿蝇、大头金蝇和巨尾阿丽蝇为优势种群。结论柳州市区蚊蝇密度较高,应在以环境治理为主的综合防制策略基础上,结合种群和密度消长等生态学特点科学开展防制。

Objective To understand the pattern of annual variation and population constitute of mosquitoes and flies,to provide scientific basis for establishing control and prevention measures.Method Using manual-power-per-hour-trapping and cage trapping to monitor the density of mosquitoes and flies respectively.Results The density peak of mosquitoes appeared at the second and the fourth quarter,Culex quinquefasciatus was the dominant specie.There were two density peaks of flies in February and July of 2008,and in April,June,August and September of 2009.Lucillia sericata,chrysomya megacephala and aldrichina grahami were the dominant species.Conclusions The density of mosquitoes and flies were higher in Liuzhou.At the basis of comprehensive prevention and control measures,combined the ecology characteristics of population and density fluctuation,carried on prevention and control strategies.
