pine beetle reseach

here are some things I learned on pine beetles

-if you cut open a pine beetle attack tree you would see blue rings and tunnels.
-the most common trees to get attacked are ones that are not growing quickly and droght or fire.
-after a pine beetle attack there are many younger trees that are well spaced.
-to protect a tree from beetles you can spray it or you can spray the beetles.
-once MBP infests a tree there is nothing worth doing that would work well.
