Abstract
Examined the influence of generation time on the rate of evolution of pesticide resistance in arthropod pests. Data integrated information on resistance evolution, generation time and other biological parameters for 682 North American arthropod pests. The data did not support a linear relationship between generations per year and the evolution of resistance, revealing instead a nonlinear and highly variable relationship, with peak rates of resistance evolution for species with intermediate generation times. Per-generation fitness values for genotypes conferring resistance to pesticides or genotypes conferring increased fitness in response to any density-independent selective agent are related exponentially to generation time, resulting in the independence of generation time and the rate of response to selection in the simplest-case model. -from Authors
