Aedes guamensis Farner & Bohart is indigenous to Guam but A. albopictus is known to have arrived in 1944. The larval ecology of the two species is very similar; both species breed in tree holes, coconut shells, and other natural and man-made water containers. The purpose of the study was to compare the relative densities of larval populations of the two species with those determined in a survey made in 1948-49. The results suggest that as the population density of A. albopictus increased, that of A. guamensis decreased by as much as about 95% in artificial containers, and by 30% or more in natural breeding habitats. Since there seems to be no environmental factor involved in rendering the breeding places unsuitable for A. guamensis, the reduction in A. guamensis populations may be, in part, the result of competition from A. albopictus.
关岛伊蚊（Farner & Bohart）原产于关岛，但白纹伊蚊于1944年传入。这两个物种的幼虫生态非常相似；它们都在树洞、椰子壳以及其他天然和人造水容器中繁殖。本研究的目的是将这两个物种幼虫种群的相对密度与1948 - 1949年调查确定的密度进行比较。结果表明，随着白纹伊蚊种群密度的增加，关岛伊蚊在人工容器中的种群密度下降了约95%，在自然繁殖栖息地下降了30%或更多。由于似乎没有环境因素使繁殖地不适宜关岛伊蚊生存，关岛伊蚊种群数量的减少可能部分是白纹伊蚊竞争的结果。
