在泰国乡村（n = 9,637 名女性和 n = 11,988 名男性）每周从房屋内外吸入成年埃及伊蚊（L.），为期 3 年，在波多黎各圣胡安的住宅区（n = 5,941 名女性和 n = 6,739 名男性）持续 2 年。在泰国，温度和降雨量属于不同的季节类别，但只有温度与雌性丰度的波动相关。收集蚊子之前 6 周的平均每周温度和收集期间的每周最低温度与雌性丰度的相关性最高。考虑年度变化显着改善了泰国的温度和蚊子丰度模型。在波多黎各，温度（而不是降雨量）可以分为季节性模式。两者都与雌性丰度的变化无关。在这两个地点，绝大多数雌性都是在房屋内收集的，并且大多数都含有血粉。大多数普通雌性是在外面收集的。翅膀长度（雌性体型的指标）与胎次、卵发育或肿胀状态不相关，这表明喂养成功和存活率不受雌性体型的影响。在这两个地点，雌性几乎完全以人类宿主为食（大于或等于 96%），这种模式不会随季节变化。在波多黎各，室外收集的蚊子中检测到的非人类血粉含量高于室内收集的蚊子；在泰国没有发现这种差异。解剖雌性的肠道内容物表明，泰国人口中的雌性比伊伊蚊的年龄分布更年轻，并且更频繁地吸食血液。波多黎各的埃及伊蚊。我们的结果表明，该物种的生物学特性在不同地点和一年之间可能存在显着差异。
Aspiration collections of adult Aedes aegypti (L.) were made weekly from inside and outside of houses for 3 yr in a rural Thai village (n = 9,637 females and n = 11,988 males) and for 2 yr in a residential section of San Juan, Puerto Rico (n = 5,941 females and n = 6,739 males). In Thailand, temperature and rainfall fell into distinct seasonal categories, but only temperature was correlated with fluctuations in female abundance. Average weekly temperature 6 wk before mosquitoes were collected and minimum weekly temperature during the week of collection provided the highest correlations with female abundance. Accounting for annual variation significantly improved Thai models of temperature and mosquito abundance. In Puerto Rico, temperature, but not rainfall, could be categorized into seasonal patterns. Neither was correlated with changes in female abundance. At both sites the vast majority of females were collected inside houses and most contained a blood meal. Most teneral females were collected outside. Wing length-an indicator of female size-and parity, egg development or engorgement status were not correlated, indicating that feeding success and survival were not influenced by female size. At both sites, females fed almost exclusively on human hosts (greater than or equal to 96%), a pattern that did not change seasonally. In Puerto Rico more nonhuman blood meals were detected in mosquitoes collected outside than inside houses; no such difference was detected in Thailand. Gut contents of dissected females indicated that females in the Thai population had a younger age distribution and fed more frequently on blood than did Ae. aegypti in Puerto Rico. Our results indicated that aspects of this species' biology can vary significantly from one location to another and 1 yr to the next.
