A smaller bark beetle often found in spruce is the foureyed spruce bark beetle Polygraphus rufipennis. The insect has a 1-, 2-, or 3-year life cycle, with 2-year being the most common, in which the flight and attack period starts in June or soon after most of the snow around the trees has melted.
Dendroctonus micans, the great spruce bark beetle, is a species of bark beetle native to the coniferous forests of Europe and Asia. The beetles burrow into the bark of spruce trees and lay eggs which develop into larvae that feed on the woody layers under the bark.
Rhizophagus grandis is a species of predatory beetle in the family Monotomidae. [1] R. grandis is a specialist predator on the larvae of the great spruce bark beetle (Dendroctonus micans), a pest of spruce trees (Picea), and is found in Eurasian forests where its prey is found.

Elatobium abietinum feeds by sucking sap from spruce needles, often causing defoliation of older needles and wilting of young growth. The presence of the aphids weakens the tree by decreasing growth rates and making it more susceptible to attack by other pests such as the spruce beetle (Dendroctonus rufipennis). Serious defoliation can kill the ...
In the 1940s, spruce bark beetle populations began to rise in the area of the Fraser Plateau. This killed many trees that were unable to be salvaged, and may have informed the decision to clearcut the future Bowron River outbreak. All known outbreaks of spruce bark beetle have accumulated in woody debris caused by logging or windthrow. [3]
