One of the most promising tools for reducing natural resource productivity losses due to spruce beetles (Dendroctonus rufipennis (Kirby) in Alaska involves the use of semiochemicals. Results of past research and development activities on spruce beetle semiochemicals suggest a high probability that successful management systems can be developed through an aggressive research and development effort. From 1988 to 1993, a cooperative project between Forest Health Management, USDA Forest Service, Alaska Region, and the Pacific Northwest Research Station was conducted to develop operational use strategies employing semiochemicals to manage spruce beetle populations. These management strategies were divided into those utilizing aggregation semiochemicals for trap out and diversion trapping of beetles, and the antiaggregation pheromone MCH formulated as beads and bubble caps to prevent or reduce infestation of stands and logging slash. Results to date have been inconclusive but the use of semiochemical mixes is promising if applications can be adapted for cold climates.
