Abstract
The application of the MacArthur-Wilson equilibrium biogeography model to insect hosts and their parasites is discussed and encouraged. Colonization of the gypsy moth, Lymantria dispar (L.), by parasites following its accidental introduction to eastern North America is used as evidence that dynamic equilibrium exists between the immigration of new parasite species to an insect host and the extinction of species already present. Although these results are in part consistent with the nonequilibrium hypotheses of Price (1980), the historical interactions between the gypsy moth and its parasites in North America closely adhere to the predictions of the MacArthur-Wilson equilibrium model.
