As an update, I'm calling the La Bourgeoisie dead. When ambrosia beetles attack, they infect the tree with a fungus that can also kill the tree. This is what the fungus-infected tree looks like.
It was a heathy tree that the ambrosia beetle attacked on June 7th. It was the only tree that I didn't cut to the ground because it only had 1 hole near the top, and I chopped well beneath it. It took a sudden dramatic turn for the worse about 1 week ago when leaves began to wilt. Initially, I thought it was only heat, but it never recovered. The tree died in about 1 week in mid-July.
