Experimental observations, made outdoors during the dry and wet seasons in Trinidad, confirm earlier findings regarding the diel pattern of entry to ovitraps and oviposition there and the taking of more than one bloodmeal during a single gonotrophic cycle. For 6-h but not for 6-h exposure periods, significantly more eggs were laid in the morning peak during the dry season than during the wet season. At the study site females were encountered singly, and only in ovitraps that contained eggs. With regard to their gonotrophic status, we conclude that, when captured, most and probably all of these females were about to oviposit, were in the process of ovipositing or had just finished ovipositing, and moreover that the laid eggs in an ovitrap were usually the product of a single female. There was no indication that females normally enter an ovitrap in the early afternoon 2 or more hours before ovipositing there.
在特立尼达的干湿两季于户外进行的实验观察，证实了先前有关进入诱蚊产卵器的日节律模式、在当地的产卵情况以及在单个生殖营养周期内摄取不止一次血餐的研究结果。对于6小时的暴露期而非6小时以上的暴露期，旱季早晨高峰期产下的卵显著多于雨季。在研究地点，雌蚊是单独被发现的，且仅在装有卵的诱蚊产卵器中出现。关于它们的生殖营养状态，我们得出结论，当被捕获时，这些雌蚊中的大多数甚至可能全部即将产卵、正在产卵或刚刚完成产卵，而且诱蚊产卵器中所产的卵通常是单个雌蚊的产物。没有迹象表明雌蚊通常会在下午早些时候在那里产卵前两小时或更长时间进入诱蚊产卵器。
