通过在 14-38°C 的一系列恒温条件下饲养，研究了温度对未成熟阶段埃及伊蚊 (L.) 生长速率和存活率的影响。在添加了足够食物（面包酵母）的水中。通过将卵浸入水中来孵化幼虫，连续分成四组，每组之间间隔六小时，最后一组孵化后六小时，此后每隔 24 小时记录每组中存活的幼虫并转移到淡水和食物中，记录剩余的蜕皮。达到任何给定阶段的平均时间被视为 6 小时的中点。完成前一阶段的个体数量达到最终完成个体总数的 50% 的时期。从刚孵化的幼虫到成虫的发育温度和时间的关系曲线是双曲线，除了极端情况。龄越晚，生长最快的温度越低。发育阈值在 9°C 到 10°C 之间，发育零度为 13.3°C，平均热常数（16°C 到 32°C 之间）为 2,741 度/小时。允许从刚孵化的幼虫发育成成虫的最高和最低温度分别为36°C和14°C。连续四个幼虫阶段和蛹阶段的平均持续时间（以新孵化幼虫到达成虫阶段所需时间的百分比表示）分别为 14.6、13.9、17.5、33.3 和 20.6。
The effect of temperature on the growth rate and survival of the immature stages of Aëdes aegypti (L.) was studied by rearing them at each of a series of constant temperatures from 14–38°C. in water to which adequate food (bakers' yeast) was added. Larvae were hatched, by immersing eggs in water, in four successive groups with an interval of six hours between each, and six hours after the last group hatched, and every 24 hours thereafter, those surviving in each group were recorded and transferred to fresh water and food, the exuviae remaining being recorded. The average time at which any given stage was reached was taken as the mid-point of the 6-hr. period within which the number of individuals that had completed the previous stage reached 50 per cent, of the total that finally did so.The curve relating temperature and time of development from newly hatched larva to adult is hyperbolic, except at the extremes. The later the instar, the lower is the temperature at which growth is most rapid. The threshold of development was between 9° and 10°C., the developmental zero 13.3°C., and the average thermal constant (between 16° and 32°C.) 2,741 degree-hours. The highest and lowest temperatures permitting development from newly hatched larva to adult were 36° and 14°C., respectively. The average durations of the four successive larval stages and the pupal stage, expressed as percentages of the time taken for newly hatched larvae to reach the adult stage, were 14.6, 13.9, 17.5, 33.3 and 20.6, respectively.
