Abstract:

Objective We monitored the adult mosquito densities during 2011 to 2014, in order to provide a reference for preventing and controling outbreaks of the Japanese encephalitis. Methods During April to November of 2011 to 2014, we used light trapping method to monitor adult mosquito density at different geographic locations and the data were analyzed using SPSS software. Results The predominant mosquito species in different habitats were different, Culex tritaeniorhynchus accounted for 91.39% in livestock shed. The predominant mosquito species in other various habitats was Cx. pipiens pallens which accounted for more than 70%. Peak season was in June, July and August. Conclusion The overall mosquito density was low in Ningbo city, we should strengthen the monitoring of mosquito density in livestock shed. We should implement mosquito management tactics in April and May before the onset of the peak mosquito density.

摘要:

目的 通过2011-2014年连续4年对流行性乙型脑炎(乙脑)媒介成蚊的密度监测,分析蚊种密度变化规律,为有针对性防控乙脑暴发提供参考依据。方法 2011-2014年每年4-11月的上下旬采用光诱法各进行一次成蚊密度监测,按不同地理方位选择监测点,使用SPSS软件对结果进行统计学分析。结果 不同生境中的优势蚊种差异明显,牲畜棚以三带喙库蚊为优势蚊种,占捕获总数的91.39%;其他各生境中均以淡色库蚊为优势蚊种,构成比均 >70%,6-8月为蚊密度高峰季节。结论 宁波市蚊媒密度总体维持在较低水平,应对牲畜棚蚊媒密度加强监测频率,加大消杀力度,在蚊密度高峰来临前的4、5月应进行全面的灭蚊工作。
