3种媒介伊蚊监测方法在登革热疫点中的应用及相关性研究

Study on the correlation of three monitoring methods and application in epidemic area of dengue fever

目的研究布雷图指数法、诱蚊诱卵器法与双层叠帐法3种监测指标之间的相关性,评价3种监测方法在登革热疫点中的实用效果,为登革热疫点合理选择监测方法提供参考。方法 2014年10-11月,选择深圳市某医院的休息花园作为试验现场,用布雷图指数法、诱蚊诱卵器法和双层叠帐法3种方法监测小区蚊虫密度。结果登革热疫点由于大力消杀蚊虫,布雷图指数、诱蚊诱卵器指数和叮咬指数3种监测指标间差异无统计学相关性(P>0.05)。风力与叮咬指数呈负相关,相关系数r=-0.837,P=0.014。结论仅依靠布雷图指数不能全面评估疫点媒介状况,双层叠帐法是登革热应急监测中不容忽视的一种监测方法。

Objective To explore the correlation of monitoring methods of Bretu index, Mosq- ovitrapand ＂Double- mosquito net＂, and evaluate the practical value of them. In order to provide the reference for choosing the proper monitoring methods in epidemic area of dengue fever. Methods Onegarden of hospital in Shenzhen was selected as the experiment site, andthe mosquito density was monitored inside by three different monitoring methodsduring October to November 2014. Results More operations are planned in epidemic area of dengue fever. There is no statistically significant correlation amongBreteau Index, Mosquito oviposition Index and Bites Index （P〉0.05）. Conclusion The result of Breteau Index may not be able to comprehensively evaluate the mosquito density in epidemic area of dengue fever. ＂Doublemosquito net＂ method, a kind of monitoring method for adult mosquito can be complementary.
