Pine wilt disease
"The pine wilt disease is caused by a microscopic nematode, Bursaphelenchus xylophilus, sometimes known as the pinewood nematode. It is transmitted in Missouri by a long-horned beetle vector, Monochamus carolinensis. It is isolated and identified as a serious disease problem in the State Extension Diagnostic Laboratory in the Plant Pathology Department of the University of Missouri in 1979."--First page.Einar W.

Tree decline - what is it?
"A natural forest typically begins as a large group of small trees, perhaps as many as several thousand to the acre. Over a period of many years, the numbers are reduced to only a few large trees per acre. Foresters, farmers and gardeners have long realized that an acre of land can produce only a certain amount of plant growth for either many small stems or for a few large ones."--First page.John P. Slusher (School of Forestry, Fisheries and Wildlife), Einar W. Palm (Department of Plant Pathology), Marc J. Linit (Department of Entomology), and Gary Long (Department of Horticulture)New 7/88/5

Cerambycids as plant disease vectors with special reference to pine wilt
The genus Monochamus Dejean belongs to the subfamily Lamiinae of the family Cerambycidae, which is one of the largest and most important among wood-boring families (Linsley 1961). Species from this genus are called “pine sawyers” because the larvae make a loud noise as they tunnel within the wood of host trees. They feed on conifers and broad-leaved trees. In Japan, some species feed on both (Kojima and Nakamura 2011). Many species attack dying, newly dead, or freshly cut trees of the genera Pinus L., Picea Mill., and Abies Mill., and are considered secondary pests. © 2017 by Taylor & Francis Group, LLC
