在2001年雨季，登革热病媒埃及伊蚊和Ae.在巴西里约热内卢州的两个城市（里约热内卢和新伊瓜苏）和佛罗里达州的两个城市（棕榈海滩和博卡拉顿）的不同生境中检查了白纹伊蚊。在城市，郊区和农村的栖息地在这两个领域的产卵陷阱收集。我们的假设是，丰富度和频率的发生Ae。埃及伊蚊和白纹伊蚊受到城市化程度提高的相反影响，但只得到部分支持。城市，栖息地，以及它们之间的相互作用显着影响这两个物种的丰度。拥有大量Ae的城市。埃及人也有很高的Ae丰度。白纹伊蚊这两个物种在里约热内卢州的城市最丰富，在博卡拉顿最低。生境对Ae的丰度有显著的反作用.埃及伊蚊和埃及伊蚊。白纹伊蚊总的来说，Ae.埃及是最普遍的高度城市化地区和Ae。白纹伊蚊在里约热内卢州和佛罗里达的农村、郊区和植被覆盖的城市地区。然而，这两个物种的丰度是相似的，在大多数郊区。发生频率的分析表明，一个意想不到的高水平的共同出现的两个物种在同一产卵陷阱。尽管有不同的地理起源的Ae。虽然白纹伊蚊在巴西和美国的栖息地非常相似，但这两个国家最近的入侵者所使用的栖息地非常相似。
During the rainy season of 2001, the incidence of the dengue vectors Aedes aegypti and Ae. albopictus was examined in different habitats of two cities (Rio de Janeiro and Nova Iguacu) in Rio de Janeiro State, Brazil, and in two cities (Palm Beach and Boca Raton) in Florida. Oviposition trap collections were performed in urban, suburban, and rural habitats in both areas. Our hypothesis that the abundances and frequencies of occurrence of Ae. aegypti and Ae albopictus are affected in opposite ways by increasing urbanization was only partially supported. City, habitat, and their interaction significantly affected the abundance of both species. Cities with high abundance of Ae. aegypti also had a high abundance of Ae. albopictus. The two species were most abundant in the cities of Rio de Janeiro state and the lowest in Boca Raton. Habitat bad a significant but opposite effect on the abundances of Ae. aegypti and Ae. albopictus. In general, Ae. aegypti was most prevalent in highly urbanized areas and Ae. albopictus in rural, suburban, and vegetated urban areas in Rio de Janeiro state and Florida. However, abundances of the two species were similar in most suburban areas. Analyses of frequencies of occurrence showed an unexpected high level of co-occurrence of both species in the same oviposition trap. Despite the different geographical origins of Ae. albopictus in Brazil and the United States, the habitats used by this recent invader are remarkably similar in the two countries.
