目的分析宜昌市居民区2009-2010年登革热媒介监测结果,为进一步监测及制定防控措施提供参考依据。方法对2009年、2010年监测点调查资料进行分析。结果伊蚊幼虫孳生地各指标均呈上升后下降趋势,2009年明显高于2010年同期水平,且在数值上2009年的波动较2010年更显著。经统计学检验,2年中各月份同期比较布雷图指数差异有统计学意义,蚊密度分布差异没有统计学意义。结论居民区采用孳生地管理和文化防治相结合的措施,能有效地将居民区内白纹伊蚊幼虫孳生率和成蚊密度控制在较低水平。
Objective To analyze the monitoring results of Dengue Medication from 2009 to 2010 in residential areas in Yichang City and provide reference for further monitoring and formulation of prevention and control measures. Methods The survey data of monitoring points in 2009 and 2010 were analyzed. Results The indexes of breeding grounds for the larvae of Aedes albopictus all showed an upward trend and then a downward trend. Their levels in 2009 were significantly higher than those in the same period of 2010, and the fluctuations in 2009 were more significant than those in 2010. The statistical tests showed that there was significant difference in the Brettimer index between the two months in each month and the mosquito density distribution difference was not statistically significant. Conclusion The residential areas with breeding ground management and cultural control measures combined can effectively control the residential area of Aedes albopictus larvae breeding and mosquito density at a low level.
