Primary forest pests

in ColoradoBark beetles

(e.g., Mountain pine beetle, Douglas-fir beetle, Ips engraver beetle) Stem and wood boring insects

(e. g., Pine sawyer, Black horned pine beetle, Flatheaded woodborer) Shoot and twig borers

(e. g., White pine weevil)Foliage feeding insects

(e. g., Western spruce budworm, Douglas-fir tussock moth, Tiger moth, Western tent caterpillar)

Sucking insects (e. g., aphids, scales, mealybugs, psyllids, spittlebugs).

Gall insects(e. g., Cooley spruce gall aphid, Piñon spindle gall)

Mountain pine beetle (MPB) (Dendroctonus ponderosae)(Family: Scolytidae, Coleoptera)

1. One-year life cycle in Colorado.2. Larvae overwinter under barks.3. Majority of adults exit trees during late July (lodgepole pine) and mid-August (ponderosa pine).

To illustrate the FIMN:
