在提供五种营养处理的队列中监测埃及伊蚊的每日存活率和产卵量：水、2%蔗糖、活鸡血加水、血液加2%蔗糖和单独血液。这些雌性的中位死亡时间（LT50）分别为6、54、16、12和29 d。在含有寄主的任何处理中，雌虫产卵数无显著差异。仅靠血液维持生命的雌性在一生中产卵的数量与能获得糖的雌性一样多，甚至更多，而后者的寿命更长。只吃糖的雄性存活时间明显长于其他任何一种处理方式。体型大的和体型小的，嗜糖的Ae。在泰国一个村庄被标记、释放和重新捕获的埃及伊蚊雌性，以及从出现到释放的36 +/- 12小时内接受糖或糖加血治疗的重复队列存活下来。这些结果表明，Ae。如果为埃及伊蚊提供碳水化合物来源，它们在实验室里的寿命会更长，但与糖喂养相关的存活率提高并不能提高繁殖成功率。
Daily survivorship and fecundity of Aedes aegypti mosquitoes were monitored for cohorts provided with five nutritional treatments: water, 2% sucrose, blood from a live chicken plus water, blood plus 2% sucrose, and blood alone. The median mortality time (LT50) for these females was 6, 54, 16, 12, and 29 d, respectively. There was no significant difference in the number of eggs laid by females in any of the treatments containing a host. Females maintained on blood alone laid as many or more eggs during their lifetime as females with access to sugar who had a greater life expectancy. Males maintained on sugar alone survived significantly longer than those in any of the other treatments. Large- and small-bodied, sugar-starved Ae. aegypti females that were marked, released, and recaptured in a Thai village survived as well as the replicate cohorts that received sugar or sugar plus blood during the 36 +/- 12 h period from emergence until their release. These results indicate that Ae. aegypti females live longer in the laboratory if they are provided a source of carbohydrate, but the increased survival associated with sugar feeding does not increase reproductive success.
