The Douglas-fir tussock moth is a native defoliator which periodically reaches outbreak proportions in western North America, causing economically important damage to its primary host, the interior Douglas-fir. The research and development of a management system for this defoliator over the past 15 years is reviewed in detail. The various data from field trials supporting this system are presented and components of this management system are briefly mentioned. The operational testing of this management system was successful, and supporting data are presented and discussed. It is recommended that this operationally proven management system be used as a template for the development of similar systems for other defoliators.
