We attempt to introduce the general insect ecologist to the uses and advantages of system simulation in the study of insect population dynamics and pest management. The systems simulation approach is defined, and the methodology outlined in terms of objectives, system definition, and model formulation, validation, manipulation and adaptation. Simulation procedures are described using examples from bark-beetle (Scolytidae) population dynamics. A simple simulation model of bark beetle dispersal and host colonization is used to illustrate elementary simulation methods, and the incorporation of a management strategy, in the form of traps baited with aggregating pheromones, illustrates the potential of gaming in solving management problems.
