A description of the recent history of spruce budworm, Choristoneura fumiferana (Clemens), in North America is discussed in the context of its population periodicity. The dynamics of budworm populations and its economic impact on spruce-fir forests necessitated the development of a spruce budworm pheromone-trapping network for monitoring population densities. Herein, the evolution of the network is discussed. The advent of using spatial analysis techniques in ecology at a landscape level and the adoption of these techniques to spruce budworm data analysis are presented. A set of software tools was developed to use these techniques to analyse budworm pheromone-trap data. Some of the issues that have arisen in coordinating and 'managing this data set are described. How these techniques can be employed to manage budworm populations is presented.
