长江流域白纹伊蚊刺叮活动节律及孳生情况调查

Survey of biting habits and breeding state of Aedes albopictus in the Yangtze River basin

目的了解甘肃省长江流域地区登革热媒介白纹伊蚊刺叮活动节律及孳生情况。方法人诱法、电动吸蚊器、容器法、捕虫网捕捉成蚊。结果长江流域白纹伊蚊刺叮活动主要是在白天,以午后高峰为主,上午9时和午后13时各出现一个小高峰,下午18时达最高峰。密度为78只/人工小时。在不同生境调查各类积水容器431个,阳性容器80个,容器指数为18.56%。经观察甘肃省长江流域白纹伊蚊的交配没发现群舞现象。结论该地区白纹伊蚊密度较高,依据其活动节律及孳生情况,需采取综合防治措施,做好灭蚊防病工作。

Objective To find out the biting rhythm and the breeding state of Aedes albopictus in the Yangtze River basin of Gansu Province,and the most important vector for dengue fever in China.Methods Human-leg catch,electrically operated attracts the mosquito,potometer,sweep net to capture adult mosquitoes.Results The biting activity of Ae.albopictus mainly arised in the daytime,the main peak in the afternoon.The small peaks were at 9 am and 1 pm.It reached the highest at 6 pm.Density was 78 pieces per man-hour.431 water containers in various types were investigated in different habitats,the positive containers were 80,and the container index was 18.56%.The mating group dance of Ae.albopictus wasn＇t observed.Conclusion Based on the ecological characteristics of Ae.albopictus in the Yangtze River basin,it is necessary to control the mosquitoes by integrated vector management,and further to control its borne diseases.
