Pine Wilt Disease
Pine wilt is caused by a plant parasitic nematode referred to as the pine wood nematode, Bursaphelenchus xylophilus. The nematode is vectored by pine sawyers of the genus Monochamus and kills the tree by feeding and reproducing in the resin canals of the branch and trunk. The pine wood nematode was first reported in the United States in 1931 but was not recognized till 1979 in Missouri on Scots pine as a pathogen. Following the discovery in Missouri, the disease was discovered in southeast Kansas the same year.
