DescriptionThe eastern larch beetle (Dendroctonus simplex LeConte) exists throughout the range of tamarack (Larix laricina (Du Roi) K. Koch) in interior Alaska where it has a 1-year life cycle. Beetles overwinter as adults in the bark of the trunk below snowline in infested trees. Tamarack trees that are slow growing because of repeated defoliation by larch bud moth (Zeiraphera sp.) or that inhabit cold wet river bottom sites underlain with permafrost are usually susceptible to attack by eastern larch beetles.
