以前关于天气对波多黎各埃及伊蚊动态影响的研究表明，降雨是未成熟蚊子种群和登革热发病率的重要驱动因素，但主要是在该岛的干燥地区。我们对Ae进行了纵向研究。在波多黎各的圣胡安市的大都会区的两个街区，降雨量更均匀地分布在全年。我们评估了降雨，温度和人类活动对成年Ae的时间动态的影响。埃及伊蚊和产卵用BG-哨兵诱捕器监测成蚊的变化，用CDC增强的诱蚊产卵器监测产卵活动。在这两个社区的一年中干燥和潮湿的部分进行了蛹调查，以确定人类和雨水对蚊子繁殖的贡献。在研究期间，将每个社区的苔藓动态与各自城市的登革热发病率进行了比较。结果表明：1.大多数puppeles产生的容器由人管理，这解释了成年蚊子的流行，在降雨量不足的时候; 2。第一次记录了水表作为Ae的生产栖息地。埃及; 3.尽管波多黎各有可靠的自来水供应和积极的轮胎回收计划，储水容器和废弃轮胎是重要的蚊子生产者; 4。蚊子密度的高峰出现在登革热发病率最高之前; 5. AE.埃及伊蚊的动态受天气和人类活动的影响，产卵与登革热发病率显著相关。以前关于天气对波多黎各埃及伊蚊影响的研究表明，降雨影响了岛上干燥地区的蚊子数量和登革热发病率。我们研究了Ae的时间变化。在全年降雨量分布比较均匀的地区，埃及人的生活水平也很高。用BG-哨兵诱捕器监测成蚊的变化，用CDC增强的诱蚊产卵器监测产卵活动。我们还在一年中干燥和潮湿的部分计算了装有水的容器中的蚊蛹数量，以确定人类和降雨对蚊子繁殖的贡献。在研究中（2007年11月至2008年12月）调查的城市中，将苔藓动态与登革热发病率进行了比较。我们发现，人口的Ae。埃及登革热受天气和人类活动的影响，在雨季，蚊子密度的高峰出现在登革热发病率最高之前。尽管波多黎各有可靠的自来水供应和积极的轮胎回收计划，储水容器（例如，5-加仑桶、桶）和废弃轮胎是重要的蚊子生产者。我们还首次记录了水表是Ae的重要生产者。埃及人。这项纵向研究有助于更好地了解流行国家的天气，人类行为，蚊子媒介和登革热病毒传播的复杂动态。
Previous studies on the influence of weather on Aedes aegypti dynamics in Puerto Rico suggested that rainfall was a significant driver of immature mosquito populations and dengue incidence, but mostly in the drier areas of the island. We conducted a longitudinal study of Ae. aegypti in two neighborhoods of the metropolitan area of San Juan city, Puerto Rico where rainfall is more uniformly distributed throughout the year. We assessed the impacts of rainfall, temperature, and human activities on the temporal dynamics of adult Ae. aegypti and oviposition. Changes in adult mosquitoes were monitored with BG-Sentinel traps and oviposition activity with CDC enhanced ovitraps. Pupal surveys were conducted during the drier and wetter parts of the year in both neighborhoods to determine the contribution of humans and rains to mosquito production. Mosquito dynamics in each neighborhood was compared with dengue incidence in their respective municipalities during the study. Our results showed that: 1. Most pupae were produced in containers managed by people, which explains the prevalence of adult mosquitoes at times when rainfall was scant; 2. Water meters were documented for the first time as productive habitats for Ae. aegypti; 3. Even though Puerto Rico has a reliable supply of tap water and an active tire recycling program, water storage containers and discarded tires were important mosquito producers; 4. Peaks in mosquito density preceded maximum dengue incidence; and 5. Ae. aegypti dynamics were driven by weather and human activity and oviposition was significantly correlated with dengue incidence. Previous studies on the influence of weather on Aedes aegypti in Puerto Rico suggested that rainfall influenced mosquito populations and dengue incidence in the drier areas of the island. We studied temporal changes in Ae. aegypti in areas where rainfall is more uniformly distributed throughout the year. Changes in adult mosquitoes were monitored with BG-Sentinel traps and oviposition activity with CDC enhanced ovitraps. We also counted the number of mosquito pupae in containers with water during the drier and wetter parts of the year to determine the contribution of humans and rainfall to mosquito production. Mosquito dynamics was compared with dengue incidence in the municipalities investigated in the study (November 2007–December 2008). We found that the population of Ae. aegypti was driven by weather and human activities, and peaks in mosquito density preceded maximum dengue incidence during the rainy season. Even though Puerto Rico has a reliable supply of tap water and an active tire recycling program, water storage containers (e.g., 5-gal pails, drums) and discarded tires were important mosquito producers. We also documented for the first time that water meters are important producers of Ae. aegypti. This longitudinal study contributes to a better understanding of the complex dynamics of weather, human behavior, mosquito vectors, and dengue virus transmission in an endemic country.
