The Douglas-fir tussock moth, Orgyia pseudotsugata (Mcd.), is an economically important defoliator of Douglas-fir and true firs in western North America. Periodic outbreaks have been recorded in most western states and British Columbia. In 1974 the U.S. Department of Agriculture initiated the four-year Expanded Douglas-fir Tussock Moth Research and Development Program to provide: (1) a short-range opportunity to summarize and put into use existing methods to reduce damage, and (2) a longer range opportunity to develop knowledge necessary to prevent or suppress future outbreaks. Program objectives have been met on schedule through the first three years, and the task in the fourth year is to document and disseminate the findings.
