We examine methods of incorporating parameter uncertainty into risk assessment models for the evolution of insect resistance to insecticides and plant-pesticides. In particular, we determine the impact of varying the variance associated with a parameter as well as the function from which we resample parameters from within that potential variation.

Species 1: Coleoptera Chrysomelidae Diabrotica virgifera virgifera (Western corn rootworm)
Keywords: insecticide resistance, population genetics
