【摘要】 目的比较和分析世博工程建设对蚊虫种群动态变化的影响。方法 2007年和2008年的3-11月间开展每旬一次的CO2诱捕法成蚊监测。结果 2007年和2008年蚊虫的密度高峰均为7月和10月;2008年监测到的淡色库蚊数量较2007年下降了54.5%,构成降至43.5%;白纹伊蚊的数量上升了47.3%,构成比上升至54.5%;三带喙库蚊2008年比2007年上升了400%;2008年蚊虫消长最高峰值明显低于2007年,仅为2007年峰值的2/3。结论工程建设的开展和环境的改变未影响该区域蚊虫的种群构成,但3种蚊虫的数量构成发生了明显的变化;对蚊虫密度的高峰期没有影响,蚊虫的平均密度和消长变化的最高峰值受到了影响。更多还原

【Abstract】 Objective To compare the influence of engineering construction to mosquito population dynamics change.Methods Using CO2 trap surveiling the mosquitoes three times a month in Huangpu district of 2010 Shanghai Expo area from March to November in 2007 and 2008.Results In 2007 and 2008,the mosquito density peak were in July and October;number of Culex pipiens pallens of adult caught in 2008 was 54.5% lower than in 2007,constitution of moquitoes dropped to 43.5%.The number of Aedes albopictus of adult was 47.3% higher than in 2007,constitution of moquitoes was up to 54.5%;number of Culex tritaeniorhynchus in 2008 was 400% higher than in 2007;the peak density of mosquitoes in 2008 was obviously lower than in 2007,only 2/3 of the peak density in 2007.Conclusion The kinds of mosquitoes within the region are still same as before,but the constitution of moquitoes changed.The seasonal fluctuation of mosquito dose not change.It shows that the environment change affects the peak density of mosquitoes.更多还原
