Pine wilt disease was first discovered in People’s Republic of China in 1982 in Nanjing City, Jiangsu Province (Cheng et al. 1986). That year only 256 dead trees were found in the city. Subsequently, the disease has spread to 10 provinces and a city: Jiangsu, Zhejiang, Anhui, Guangdong, Shandong, Jiangxi, Hubei, Hunan, Yunnan, Guizhou Provinces and ...

Pine Wilt Disease: a threat to European forestry
European Journal of Plant Pathology, 2011Bursaphelenchus xylophilus, the pinewood nematode (PWN) and causal agent of Pine Wilt Disease (PWD), was detected for the first time, in 1999, in Portugal, and in Europe. Despite the efforts of the Portuguese National Forestry and Quarantine Authorities, the disease has spread to new forest areas in the centre of mainland Portugal, in 2008, and to the ...

Pine Wilt—A Disease You Should Know
Arboriculture & Urban Forestry, 1982Pine wilt is a disease characterized by sudden death. The needles remain attached, but become reddish brown. It is currently a major problem in Japan on Pinus thunbergii and P. densiflora. It was first identified in the U.S. in Columbia, MO in 1979. It is now known in 32 states on 20 species of pine, two of larch, two of spruce, two of cedar, and on ...

Breeding for Resistance to Pine Wilt Disease
2008To cope with pine wilt disease the first resistance breeding program started in western Japan in 1978. In this program, resistant Japanese black pines (Pinus thunbergii) and Japanese red pines (P. densiflora) were selected. Subsequently, their progenies have come into wide use as resistant seedlings.

In Korea, pine trees are both culturally and spiritually important. According to the fourth forest resource survey from 1996 to 2005, pines occur widely on some 1,507,118 ha of land representing 23.5% of Korea’s forest area and 15.1% of the country’s land mass (Kwon 2006).

Effects of spring-killed pine trees on the epidemics of pine wilt disease
Applied Entomology and Zoology, 2012Pine wilt disease (PWD) is caused by the pinewood nematode (PWN), Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle, and is transmitted by cerambycid beetles. In some pine trees infected with the PWNs in Japan, foliage changes from green to brown in summer to autumn of a nematode infection year (summer- autumn-killed trees) and the others in the ...

Benzothiadiazole induces Pinus koraiensis to resist pine wilt disease
Pesticide Biochemistry and PhysiologyBenzothiadiazole (BTH) and methyl salicylate (MeSA) have been confirmed as effective inducers for numerous plant species, empowering them to fend off pathogens. In this research, we combined the relative tolerance index (RTI) and relative anti-nematode index (RAI) to assess how these two inducers influence Pinus koraiensis in resisting pine wood ...

Pathogenic Cellulase Assay of Pine Wilt Disease and Immunological Localization
Bioscience, Biotechnology, and Biochemistry, 2006The pine wilt disease caused by Bursaphelenchus xylophilus (BX), also known as the pine wood nematode (PWN), is the most devastating disease of pine trees. In this work, a high molecular weight B. xylophilus cellulase antigen (BXCa) was purified from total homogenates of nematodes.

Mechanism of cavitation development in the pine wilt disease
European Journal of Forest Pathology, 1991AbstractVolatile terpenes increase in xylem tissue after infection of Pinus thunbergii with the pine wood nematode (Bursaphelenchus xylophilus). The role of these terpenes in traeheid cavitation, which blocks xylem‐sap ascent and leads to water deficit in pine trees, was assessed.
