摘要

摘要: 目的了解三种常用白纹伊蚊监测方法在登革热风险指示中的适用性。方法 2017年12月~2018年7月，在广州市白云区两农村同时用三种监测方法进行白纹伊蚊幼虫和成蚊密度监测，并收集同期气象数据和登革热病例情况。结果幼虫和成蚊密度消长均受气温影响，各监测指标反映的白纹伊蚊密度消长趋势一致，但幼虫与成蚊密度存在差异。2017年12月-2018年2月，两监测点布雷图指数为5.66~24.53，指示风险为1~3级，诱蚊诱卵指数和成蚊密度指数分别为0~4.00和0~1只/人·h，指示风险均为0级；3月份，布雷图指数反映风险等级为3级，而诱蚊诱卵指数分别为2.13和3.77，风险为0级，成蚊密度指数分别为4只/人·h和6只/人·h，指示风险为1级和2级；4月份之后，各监测指标反映的登革热风险等级趋于一致。结论布雷图指数指示的登革热风险总是高于或等于诱蚊诱卵指数和成蚊密度指数指示的风险。诱蚊诱卵指数和成蚊密度指数能较敏感地反映白纹伊蚊的活动情况，指示登革热风险的准确性高。

Abstract: Objective To disscus the applicability of three surveillance methods for Aedes albopictus in dengue risk indication. Methods Larval and adult mosquito surveillance were conducted in two villages of Guangzhou by using three vector monitoring methods. Meteorological data and dengue cases were obtained in the same period. Results The population dynamics of larvae and adult mosquitoes were affected by temperature and their overall trend was consistent, but there were differences between the abundance of larvae and adult mosquitoes. From December to February the next year, Breteau index(BI) ranged from 5.66 to 24.53 with a risk of level 1 to 3 for dengue fever, while the mosquito and oviposition positive index(MOI) and adult-mosquito density index(ADI) were 0 to 4.00 and 0 to 1 per man-hour, respectively, indicating no risk for dengue fever. In March, compared with BI which indicated a risk of level 3, MOI were 2.13 and 3.77, respectively, representing for no risk. ADI were 4 to 6 per man-hour, indicating a risk of level 1 and level 2, respectively. After April, the dengue risk level reflected by each indicator became to be consistent. Conclusions The risk of dengue fever indicated by BI is always higher than or equal to the risk indicated by the other two. Compared with BI, MOI and ADI are more sensitively in reflecting the activity of Ae. albopictus.
