Practical Application of Pheromones in Regulatory Pest Management Programs, sterile insect release, and other methods are evaluated constantly for use in these programs. Biological control techniques are substituted for chemicals when the objective of the program can be met. Semiochemicals are becoming one of the more important tools used for survey, control, and evaluation in PPQP activities.

Pheromone-Based Suppression of Ambrosia Beetles in Industrial Timber Processing Areasolated windthrown, broken or dying hosts (Atkins, 1966). However, in industrial timber-processing operations such as dryland log sorting areas (dryland sorts) (Fig. 1) and sawmills (Fig. 2) the same attack behavior by abnormally high beetle populations constitutes a major problem.

Biomonitoring for Stored-Product Insectsngth, space and other factors, and physical traps such as perforated-cylinder grain probes and pitfall traps do not have appreciable luring capability. Pheromones, however, have added a powerful new dimension to this important procedure.

Practical Results from the Mass Trapping of , in Scandinaviast 10 years there has been a rapid growth in the population of .. . in Scandinavia. The bark beetles have become a real threat to spruce trees in south-east Norway and west-central Sweden. Several factors have caused this situation to occur. Since 1969 rainfall has been lower than average over large areas of Scandinavia.
