Choristoneura fumiferana, the eastern spruce budworm, is a species of moth of the family is also commonly referred to as the spruce budworm. It is one of the most destructive native insects in the northern spruce and fir forests of the eastern United States and range is also the widest of all the budworm species. Eastern spruce budworm populations can experience Family: Tortricidae.
This name has historically been applied to the western spruce budworm, a serious forest pest in western North America. However, in Razowski transferred the African species Archips occidentalis (Walsingham) to Choristoneura Lederer and proposed C. freemani Razowski as a replacement name for the western spruce budworm. The validity of these Cited by: 3. Choristoneura freemani, the western spruce budworm, is a species of moth of the family Tortricidae. It is the most destructive defoliator of coniferous forests in western North America. It is the most destructive defoliator of coniferous forests in western North : Insecta.

Cooperative State Research, Education, and Extension Service. United States. Department of Agriculture. The spruce budworm, Choristoneura fumiferana, Clem., is the most significant defoliating pest of boreal balsam fir (Abies balsamea (L.) Mill.) and spruce (Picea sp.) in North America. Historically, spruce budworm outbreaks have been managed via a reactive, foliage protection approach focused on keeping trees alive rather than stopping the outbreak.

Hosts: Douglas-fir, true firs, and spruce Figure 3. Adult western spurce budworm with pupal case. Symptoms/Signs: Adults are a mottled orange brown and have a wing span of 22 to 28 mm.
Eggs are white to light green in color and are laid in shingle-like masses on the underside of needles. Newly hatched larvae are cream colored with brown heads.
In the western US, the western spruce budworm annually defoliates hundreds of thousands of acres in the spruce-fir type. The spruce budworm in the upper Mid-west has been a chronic defoliator for many years. In Maine and northern New England, the spruce budworm has been at endemic levels for the past 30 years, but populations are building in.

AZ 'Swetnam, T. W.; Thompson, M. by: The western spruce budworm's life cycle generally takes 12 months, producing one generation per year. At high elevation sites the life cycle can take two years to complete.
Exact timing of the life cycle is greatly influenced by temperature. The budworm overwinters as a small larva in a silky hibernaculum (cocoon-like shelter) on the bark.Budworm outbreaks may be sustained for 25 years or more.
Host trees: Primarily Douglas-fir, with other tree species such as the true firs, larch and to a lesser degree, spruce, also impacted by the western spruce budworm.
Description and life cycle: The western spruce budworm requires one year to complete its life cycle.
