Abstract

The incorporation of pesticide resistance into a realistic economic optimization model of the interaction of Egyptian alfalfa weevil populations (EAW = Hypera brunneipennis (Boh.)) and alfalfa (Medicago sativa (L.)) is described. The model has 4 components: the population dynamics of the weevil; the dynamics of the crop; pesticide induced mortality; and the evolution of resistance in the weevil population. The paper presents the optimal within season and long-term pesticide spraying patterns after resistance develops for 2 cases: with and without information on the developments of resistance.
