Abstract: Due to environmental concerns, newer pesticides are becoming less lethal than older pesticides, thus leaving more survivors behind. Evaluating efficacy of a pesticide now requires more than just counting dead species. A deterministic, age-structured matrix model that incorporates a species' life history traits (such as birth rate, death rate and fecundity) has previously been used by ecologists. This model will be presented and discussed along with the continuous, age-structured model we introduce that involves a least-squares technique used to identify unknown parameters. We also discuss a statistical test used to test significance of additional parameters into our estimation.
