目的：评估白纹伊蚊和埃及伊蚊产卵容器和建筑物的多样性。方法：在巴西南部的里约热内卢市进行了一项研究，在2002年和2003年之间。我们调查了不同类型建筑物内的幼虫，并将发现的未成熟幼虫送往实验室进行鉴定。在可用的产卵容器中估计两种蚊子的幼虫频率。Breteau指数和建筑物感染指数进行计算和差异进行了测试，使用卡方test.Results：白纹伊蚊和埃及伊蚊阳性的建筑物类型是：住宅（83.9%）;教堂，学校，俱乐部（6.8%）;空地（6.4%）;和企业（2.8%）。在采集的9 153只幼虫中，12.0%为白纹伊蚊，88.0%为埃及伊蚊。白纹伊蚊主要在排水沟（25.4%）、罐、瓶、空瓶（23.9%）和花瓶（16.2%）中发现。埃及伊蚊比白纹伊蚊更常见（chi（2）=145.067; p < 0.001）。两种成虫在人工产卵器中的产卵频率均显著高于自然产卵器（χ 2 =31.46; p < 0.001）。2002年白纹伊蚊建筑物侵害指数和布雷托指数分别为0.3%和0.28%，2003年分别为0.4%和0.5。2002年和2003年，白纹伊蚊和埃及伊蚊的雌蚊密度分别为1.0%和1.16，3.5%和4.35，2003年分别为1.0%和1.16，2003年分别为3.5%和4.35。在住宅中的人工容器的丰富可用性，与Ae的能力。白纹伊蚊也在自然产卵容器中发现，这对它们逐渐适应人类环境有很大贡献。
OBJECTIVE: To assess the diversity of oviposition containers and buildings where females of Aedes albopictus and Aedes aegypti can be found.METHODS: A study was carried out in the city of Rio de Janeiro, Southern Brazil, between 2002 and 2003. Larvae in different types of buildings were investigated, and immature forms found were then sent to the laboratory for identification. The larval frequency for both mosquitoes was estimated in the oviposition containers available. The Breteau index and the building infestation index were calculated and differences were tested using the Chi-square test.RESULTS: The types of buildings that were positive for Aedes albopictus and Aedes aegypti were: dwellings (83.9%); churches, schools, clubs (6.8%); vacant land (6.4%); and businesses (2.8%). Of 9,153 larvae collected, 12.0% were Aedes albopictus and 88.0% were Aedes aegypti. Aedes albopictus were mostly found in drains (25.4%); cans, bottles, empty bottles (23.9%); and plant vases (16.2%). Aedes aegypti was much more frequently found than Aedes albopictus(chi(2)=145.067; p < 0.001). Both species were significantly more frequent in artificial than in natural oviposition containers (chi(2)=31.46; p < 0.001). The building infestation index and Breteau index for Aedes albopictus were 0.3% and 0.28% in 2002 and 0.4% and 0.5 in 2003, respectively. For Aedes aegypti, they were 1.0%, 1.16 in 2002 and 3.5% and 4.35 in 2003, respectively.CONCLUSIONS: The present study assessed the frequencies of Aedes albopictus and Aedes aegypti females in various types of oviposition containers and types of buildings. The abundant availability of artificial containers in dwellings, associated with the capacity of Ae. albopictus to be also found in natural oviposition containers, has greatly contributed for their gradual adaptation to human environment.
