Primary forest pests in Colorado Bark 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: Images:

Felling the infested tree Felling the infested tree blocks When epidemics Management Practices are limited Extremely high cost Relatively low cost Low cost Early detection is Critical in MPB management!

Online Report System Allow the landowners online to report any abnormality about their forest e. g., Spruce Tree Species e. g., 15 Number of trees appear this symptom e. g., leaf color change or any damage sign… Abnormality Description e. g., Mr. Collins Tel: Contact information

1. Thanks to all forest entomologists in Colorado for their long-term efforts, we now have the basic information available to develop such a network.

Forest Insect management information for MPB can be obtained by the landowners using such network Must be available in a user- oriented fashion (make it easy for the users to get the information they need!)
