In response to your boring insects. I would recommend you look at the USDA
Forest Service Agriculture handbook 654 "Silvics of North America" Vol. 1.
I looked up menziesii but, no apparent borers were recorded.  Several
other damaging  insects were though mostly defoliating insects.
If you cannot find this book feel free to contact me directly and I will
send you specific information.  Good luck.
