Commentary

Hi, thanks for your report. Asian longhorn beetle attacks hardwood trees, primarily maple, elm, horsechestnut and willow. To learn more about ALB, please visit this excellent resource by Oregon State University: http://pestdetector.forestry.oregonstate.edu/pests

Many conifers are showing signs of drought stress from 2015. Conifers show red needles one year after such stress. Many opportunistic insects and fungi are quick to take advantage of dying trees. Forest health professionals at Oregon Departmetn of Forestry and Oregon State University Extension have been fielding calls on drought stress in conifers in the Willamette Valley and Portland metro area. That is my best guess on your situation. See http://tinyurl.com/ODF-ForestHealth.

If you have some pictures of the insects, in particular the adult stage, it will be helpful in identification.

Thanks,
Wyatt
