描述了生存数据的分析方法。11种热带植物野生种群存活数据的再分析。埃及伊蚊（Aedes aegypti）、冈比亚按蚊（Anopheles gambiae）、A. funestus，A. arabiensis、阿拉伯拟步行虫A. flavirostris、黄唇圆腹蛛A. farauti、黑腹拟步行虫A. albimanus、A. darlingi，A.迷走库蚊、致倦库蚊和单形曼索尼亚]的研究表明，在大多数这些种群中，成年雌性死亡率并不像人们通常认为的那样与年龄无关，而是随着年龄的增长而增加。Gompertz函数很好地描述了大多数人口的死亡率模式，根据该函数，死亡率随年龄增加，其对数与年龄成正比。这些调查结果的流行病学影响进行了研究，通过计算长寿因素，这是一个组成部分的矢量能力，为7个这些人群。当Gompertz死亡率模型在适当情况下取代广泛使用的指数模型时，寿命系数的估计数出现了相当大的差异。
Methods are described for the analysis of survival data. The re-analysis of survival data for wild populations of 11 tropical spp. of mosquitoes [Aedes aegypti, Anopheles gambiae, A. funestus, A. arabiensis, A. flavirostris, A. farauti, A. albimanus, A. darlingi, A. vagus, Culex quinquefasciatus and Mansonia uniformis] revealed that in most of these populations the adult female mortality rates were not independent of age, as had commonly been supposed, but increased with age. The patterns of mortality of most of the populations were well described by the Gompertz function, according to which the rate of mortality increases with age in such a manner that its logarithm is directly proportional to age. The epidemiological implications of these findings were examined by calculating the longevity factor, which is a component of vectorial capacity, for 7 of these populations. Considerable differences were obtained in estimates of the longevity factor when the Gompertz model of mortality was substituted, in appropriate cases, for the widely used exponential model.
