Yes, it is the scale bug. They will, completely, destroy the tree if left untreated. You should scrape off as many as you can, then spray the tree with neem oil. This will keep them from coming back. Unfortunately, they seal themselves to the tree, so unless you, manually, remove them, then the neem oil will not affect them.
