Pine wilt is caused by a nematode called Bursaphelenchus xylophilus. These microscopic worms infest pine trees and disrupt the tree’s water conduction system, leading to rapid wilting and eventual death. The nematodes are typically spread by pine sawyer beetles, which transmit them to healthy trees when the beetles feed or lay eggs.
