This paper presents a diffusion model of larval dispersal specifically designed to account for particular aspects of postfeeding larval dispersal from the food source in organisms such as blowflies. In these organisms the dispersal of immatures includes two groups of individuals, those that are actively migrating and those that have initiated the pupation process. The classical diffusion equation in one dimension was modified to incorporate a function which describes the burying of larvae to become pupae. The analytical solution of this equation predicts oscillatory and monotonic dispersal behaviors, which are observed in experimental populations of blowfly species.
本文提出了一个幼虫扩散模型，专门用于解释诸如蝇类等生物中从食物源到幼虫的特定后摄食扩散方面。在这些生物中，幼虫的扩散包括两组个体，一组是主动迁移的个体，另一组是已经开始化蛹过程的个体。一维经典扩散方程被修改为包含一个描述幼虫变为蛹的掩埋过程的函数。该方程的解析解预测了在蝇类实验种群中观察到的振荡和单调扩散行为。
