Analysis of experimental data on longevity and fertility of females of Mediterranean fruit fly Ceratitis capitata demonstrates that flies lay fewer eggs on the average as the average life-span increases. At the same time, the values of individual life-span and the number of eggs laid are positively correlated. To explain these results, a resource model describing the allocation and reallocation of resources between two basic functions, reproduction and maintenance, was proposed. The reallocation of resources, is triggered by changes in environmental conditions such as diet changes, and the parameters of reallocation depend on the current environmental conditions. Modeling demonstrated that the results of experiments are greatly influenced by population selection and heterogeneity.
对地中海实蝇雌性的寿命和繁殖力实验数据的分析表明，随着平均寿命的增加，果蝇平均产卵量减少。同时，个体寿命值和产卵数量呈正相关。为了解释这些结果，提出了一种资源模型，该模型描述了资源在繁殖和维持这两个基本功能之间的分配和重新分配。资源的重新分配是由饮食变化等环境条件的变化触发的，重新分配的参数取决于当前的环境条件。建模表明，实验结果受种群选择和异质性的影响很大。
