holes in dying Austrian Pine tree #798446

Asked June 29, 2022, 9:12 AM EDT

i have only 1 Austrian Pine, which is dead on top as of a month or so ago. I thought is was wind damage but i see a lot of holes and hardened clumps on the bark. I have 25 white pine and many Colorado blue spruce, Black Hills spruce,, Eastern Red Cedars and 2 Mugo Pines. How do i identify the beetle or disease. How to i treat the other trees?
