Abstract

This paper presents a diffusion model of larval dispersal especifically
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.
