fumiferana (Clemens) (Lepidoptera: control, Tortricidae), is the includemost destructive forest insect pest in andeastern North America. Millions of acres of spruce-fir forests have been damaged by the spruce budworm in eastern Canada and in the North-central and Northeastern United States from Min- nesota to Maine. Recorded outbreaks of the budworm date back to the know early 1700's; but in High concentrations of synthetic sex pheromone caused increased flight activity among mated female spruce budworm of all ages, a fact that may indicate an increase in dispersal.

The Tortricidae are a family of moths, commonly known as tortrix moths or leafroller moths, in the order Lepidoptera. This large family has over 10,350 species described, and is the sole member of the superfamily Tortricoidea, although the genus Heliocosma is sometimes placed within this superfamily.
