Pine Bark Beetles

Ips spp., Dendroctonus spp.

A complex of bark beetle species that attack pine trees, including mountain pine beetle, southern pine beetle, and various engraver beetles. These insects bore through bark and can kill trees through direct feeding damage and vectored fungal diseases.

Peak Season: Adults active during warm months, with peak flight periods in spring and summer. Drought stress increases susceptibility.

Identification & Symptoms

What to Look For

Small, round entry holes in bark
Reddish-brown boring dust around holes
Yellowing and reddening of pine needles
Resin tubes or pitch masses on bark surface
Blue-stain fungi in wood galleries

Potential Damage

Direct larval feeding damage in cambium
Introduction of blue-stain fungi that blocks water transport
Rapid tree mortality in epidemic outbreaks
Massive forest die-offs during drought stress
Economic losses to timber industry

Lifecycle

Adults bore through bark to mate and lay eggs. Larvae develop in galleries under bark, pupate, and emerge as adults to attack new trees.
