许多物种分布图表明埃及伊蚊（林奈）和白纹伊蚊（Skuse）的范围重叠在佛罗里达，尽管有充分的记录范围减少的Ae。埃及人。在过去的30年里，竞争取代Ae。埃及Ae. albopictus导致了这两个物种的部分空间分离，与Ae。主要在城市避难所生活的埃及人。我们模拟了这两个物种的细尺度分布，目标是通过构建栖息地适宜性地图来捕获空间内种间竞争的结果。我们经验参数化模型，通过采样59个地点在南部和中部佛罗里达随着时间的推移，并纳入气候，景观和人口数据，以确定两个物种的栖息地适宜性的预测。我们的研究结果表明，人口密度，降水量和城市土地覆盖驱动Ae。埃及栖息地的适宜性，相比，完全气候变量驱动Ae。白纹伊蚊栖息地适宜性遥感变量（大生境）比当地收集的指标（微生境）更具预测性，虽然记录的最低日温度显示出显着的，与这两个物种的反比关系。我们发现未成年伊蚊栖息地隔离;一些城郊地区，非常适合Ae。白纹伊蚊不适合作为Ae.埃及人。精细规模的经验模型，如这里提出的精确的风险评估和改进的操作应用程序，以控制容器繁殖伊蚊的潜力。
Many species distribution maps indicate the ranges of Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) overlap in Florida despite the well-documented range reduction of Ae. aegypti. Within the last 30 yr, competitive displacement of Ae. aegypti by Ae. albopictus has resulted in partial spatial segregation of the two species, with Ae. aegypti persisting primarily in urban refugia. We modeled fine-scale distributions of both species, with the goal of capturing the outcome of interspecific competition across space by building habitat suitability maps. We empirically parameterized models by sampling 59 sites in south and central Florida over time and incorporated climatic, landscape, and human population data to identify predictors of habitat suitability for both species. Our results show human density, precipitation, and urban land cover drive Ae. aegypti habitat suitability, compared with exclusively climatic variables driving Ae. albopictus habitat suitability. Remotely sensed variables (macrohabitat) were more predictive than locally collected metrics (microhabitat), although recorded minimum daily temperature showed significant, inverse relationships with both species. We detected minor Aedes habitat segregation; some periurban areas that were highly suitable for Ae. albopictus were unsuitable for Ae. aegypti. Fine-scale empirical models like those presented here have the potential for precise risk assessment and the improvement of operational applications to control container-breeding Aedes mosquitoes.
