Abstract
Many of the classic studies of the spatiotemporal dynamics of natural enemies and their hosts consider parasitoid-host interactions. Parasitoids represent a fascinating group of insect “infections.” Adults are free-living and lay their eggs in larvae (or eggs) of host insects. Hosts die when the parasitoid(s) complete their development and adults emerge from the infected hosts. From a dynamical systems point of view parasitoid-host interactions share many features of infectious disease dynamics. It is therefore instructive to cap our discussion of spatiotemporal dynamics with a discussion of this ecological interaction.

Notes
- 1.
Recall that according to local stability theory , stability of discrete time models requires the absolute value of the largest eigenvalue of the Jacobian evaluated at the equilibrium to be smaller than 1—as opposed to continuous time models for which the requirement is that the real part must be smaller than 0.
