Summary
Introduction
We produce the population dynamics of a stage structured population, where the stages are defined by sharp biological events (egg hatching, molt, adult emergence, beginning and end of oviposition, death), by means of a stochastic individual-based model that simulates the life histories of its individuals (Judson, 1994; Berec, 2002; Buffoni et al., 2002; Buffoni et al., 2004). Aspects of the life history of an individual, such as survival probabilities, development rates and egg production, depend on its “status,” on the population size, and on external factors such as the environmental conditions (e.g. physical factors, food availability). In general, the status of an individual can be identified by means of a number of physiological variables or biometric descriptors, which describe the behavior of an individual in a given situation, and define its physiological age. The physiological age of an individual is generally described only by a variable. Here the status of an individual is individuated by its stage and its physiological age in the stage. The physiological age is defined as the percentage of development for non-reproductive individuals, and as the percentage of the potential reproductive effort for an adult female. The life history is obtained by the time evolution of the status of an individual, from birth to death, following its development and, when the individual is an adult female, the production of eggs.
