Sometimes a healthy tree can overcome the damage and survive. But, not always. You might want to contact your local Cooperative Extension office to see if there are any new ways to combat theses pests. Extension offices are located in each county. Here's a website with a list of county offices:
Best wishes with your pine tree!
