THE PINEWOOD NEMATODE:Regulation and Mitigation

Annual Review of Phytopathology, 1997
▪ Abstract  In North America, the native pinewood nematode (PWN), Bursaphelenchus xylophilus, kills exotic pines. When inadvertently introduced to Japan and other Asian countries, PWN became a destructive pest of pines. The PWN has been intercepted in pine shipments from North America to Europe, where there is concern that it may also kill pines and ...

In situ observation of pinewood nematode in wood

European Journal of Plant Pathology, 2016
In pine wilt disease, xylem dysfunction occurs in relation to nematode migration and proliferation in host tissue, but the detection accuracy of pinewood nematode (PWN), Bursaphelenchus xylophilus, in pine stem tissue remains unclear. This study describes the use of cryo-scanning electron microscopy (cryo-SEM) and fluorescein-conjugated wheat germ ...

Attraction of Pinewood Nematode to Endoparasitic Nematophagous Fungus Esteya vermicola

Current Microbiology, 2009
The investigations on attraction of nematodes to nematophagous fungi have mostly dealt with the nematode-trapping species. Esteya vermicola is the endoparasitic fungus of pinewood nematode (PWN) with high infection activity. In the present study, the attraction of PWNs to E. vermicola was investigated.

A short review of the pinewood nematode, Bursaphelenchus xylophilus

Toxicology and Environmental Health Sciences, 2020
This article provides a summary of studies on pine wilt disease (PWD). PWD is a serious threat to forests, and the damage caused by this disease results in significant economic loss. In addition, PWD adversely affects not only animals and plants, but also the human environment.

Pinewood Nematode Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle

2017
Pine wilt disease (PWD) is likely the most serious threat to pine forests worldwide. The causative agent of PWD, the pinewood nematode (PWN) Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle, engages in a symbiotic partnership with its insect vector, the Monochamus beetle, as well as associated bacteria and ophiostomatoid fungi, to successfully ...

Phytoalexins from Pinus strobus bark infected with pinewood nematode, Bursaphelenchus xylophilus

Phytochemistry, 2001
From the bark of Pinus strobus infected with pinewood nematode, Bursaphelenchus xylophilus, a stilbenoid 3-O-methyldihydropinosylvin and a flavanone (2S)-pinocembrin were isolated as active principles of inducibly produced antifungal compounds. The structures of the compounds were determined on the basis of spectroscopic analyses.

Sublethal infection of different pine species by the pinewood nematode

Plant Pathology, 2020
Abstract Bursaphelenchus xylophilus , the pinewood nematode and causal agent of pine wilt disease (PWD), is a globally destructive pine pest. PWD is favoured by high temperatures and drought, but B .

Pine Wilt Disease And The Pinewood Nematode, Bursaphelenchus Xylophilus

2009
Pine wilt disease (PWD) is one of the most damaging events affecting conifer forests (in particular Pinus spp.), in the Far East (Japan, China and Korea), North America (USA and Canada) and, more recently, in the European Union (Portugal). In Japan it became catastrophic, damaging native pine species (Pinus thunbergii and P.

Field Diagnosis of the Asymptomatic Carrier of Pinewood Nematode

2008
To prevent pine wilt disease (PWD) from spreading over pine forests, elimination of pine trees killed by the pinewood nematode (PWN), Bursaphelenchus xylophilus is desirable, though this method is very laborious and time-consuming. If such dead trees are left in the field, pathogenic nematodes and their vector, Monochamus beetles, could spread from ...
