在特立尼达，西印度群岛的国内埃及伊蚊产卵的发病率和昼夜模式进行了比较，在中间的湿季（7月和8月），使用修改的诱卵器，在无阴影的peridomestic户外网站面向东或西。沿着样带彼此靠近的站点在它们接收的总卵量上差异很大，18.2%的站点接收50.6%的卵。接收最多卵的地点靠近其他繁殖地点。以产卵数量（> 59%）和产卵次数（> 57%）衡量，西向地点的产卵率高于东向地点。产卵的昼夜模式在面向东和西的网站是非常相似的，表明太阳的方位角在产卵的时刻并不能决定一个女性是否在网站面向东或西奠定。产卵的昼夜模式类似于早期研究的双峰，但与之不同的是具有更大的早晨高峰（包括超过34%的产卵，而早期研究中约为5%）。这种双峰模式非常类似于几位作者先前描述的在人类身上着陆的昼夜周期性，并且可能接近于Ae的典型产卵模式。埃及伊蚊;人工制品可能改变了先前特征的产卵周期。在晚上显着更多的鸡蛋奠定了网站面向西比网站面向东。这些发现对有效放置诱蚊产卵器监测或抑制Ae具有重要意义。埃及，并引起了一个假设，调用响应小气候占双峰产卵模式的形式。
The incidence and diel patterns of oviposition of domestic Aedes aegypti in Trinidad, West Indies during the middle of the wet season (July and August) was compared, using modified ovitraps, in unshaded peridomestic outdoor sites facing east or west. Sites close to each other along a transect differed greatly in the total eggs they received, 18.2% of sites receiving 50.6% of the eggs. Sites receiving most eggs were close to other breeding sites. The incidence of oviposition in sites facing west, as measured by the number of eggs laid (> 59%) and by the number of occurrences of eggs (> 57%), was greater than in sites facing east. The diel pattern of oviposition was closely similar in sites facing east and west, indicating that the sun''s azimuth at the moment of oviposition does not determine whether a female lays in sites facing east or west. The diel pattern of oviposition resembled an earlier study in being bimodal but differed from it in featuring a much larger morning peak (comprising more than 34% of eggs laid v. about 5% in the earlier study). This bimodal pattern closely resembles a diel periodicity of landing on humans described previously by several authors and is probably close to the typical oviposition pattern for Ae. aegypti; an artefact may have modified the oviposition periodicity characterized earlier. In the evening significantly more eggs were laid in sites facing west than in sites facing east. These findings have implications for effective placement of ovitraps for surveillance or suppression of Ae. aegypti, and give rise to an hypothesis which invokes responses to microclimate to account for the form of the bimodal oviposition pattern.
