The establishment of an invasive species depends on reproductive success and dispersion capability in the new environment. One of the striking examples of invasion in urban environments is the mosquito Aedes aegypti Linnaeus, 1762 (Culicidae). The success of this species is primarily attributed to its ability to colonize urban environments, and some of the important adaptive strategies associated with this ability is the preference for humans as a blood source and intense occupation of residential (indoor) environments. This study evaluated the effects of location (indoor vs. outdoor) and water nutrient level (% organic matter) on the oviposition preference of A. aegypti in an urban environment. We used oviposition choice experiments to evaluate mosquito oviposition in containers holding 1:1 vs 1:0 ratios of water: organic matter placed indoors and outdoors. Eggs were sampled once per week for nine weeks. Our results revealed a strong oviposition preference for outdoor containers, with a significant preference for containers with higher concentrations of organic matter during the fifth to ninth weeks. However, mosquitoes occupying indoor environments did not prefer to lay eggs in containers with lower levels of organic matter. A better understanding of the preferences of A. aegypti regarding the nutrient level and location of oviposition containers can increase our understanding of the behavioral factors allowing mosquitoes to utilize anthropogenic environments.

蚊子 Aedes aegypti Linnaeus 的产卵偏好，1762 年（Culicidae）：城市环境生物测定

入侵物种的建立取决于在新环境中的繁殖成功和分散能力。城市环境中入侵的显着例子之一是蚊子埃及伊蚊林奈，1762 年（Culicidae）。该物种的成功主要归功于其在城市环境中殖民的能力，与这种能力相关的一些重要的适应策略是偏好人类作为血源和对住宅（室内）环境的强烈占领。本研究评估了位置（室内与室外）和水养分水平（有机物百分比）对产卵偏好的影响。A. aegypti在城市环境中。我们使用产卵选择实验来评估蚊子在装有 1:1 与 1:0 比例的水：放置在室内和室外的有机物的容器中的产卵。每周对鸡蛋取样一次，持续九周。我们的研究结果显示，人们对户外容器有强烈的产卵偏好，在第 5 到第 9 周期间，对有机物质浓度较高的容器有明显的偏好。然而，占据室内环境的蚊子不喜欢在有机物含量较低的容器中产卵。更好地了解客户的偏好A. aegypti关于产卵容器的营养水平和位置可以增加我们对允许蚊子利用人为环境的行为因素的理解。
