The reproductive strategy of the pinewood nematode (PWN), Bursaphelenchus xylophilus , is sexual amphimictic and oviparous. The incidence of intrauterine egg development and hatching in plant-parasitic nematodes is not a very common phe- nomenon. During t... see more

The genetic diversity and phylogeny of 26 isolates of Bursaphelenchus xylophilus from China, Japan, Portugal and North America were investigated based on the D2/3 domain of 28S rDNA, nuclear ribosomal Internal Transcribed Spacer (ITS) sequences, and rando... see more

Pathogenicity of the pine wood nematode, Bursaphelenchus xylophilus, to Japanese larch, Larix kaempferi, seedlings was tested with inoculation experiments under nursery conditions. Water suspensions of nematodes (mixed stages cultured on Botrytis cinerea ... see more

Twenty seven essential oils, isolated from plants representing 11 families of Portuguese flora, were screened for their nematicidal activity against the pinewood nematode (PWN), Bursaphelenchus xylophilus. The essential oils were isolated by hydrodistilla... see more

Ribosomal DNA region sequences (partial 18S, 28S and complete ITS1, 5.8S, and ITS2) of the pinewood nematode (Bursaphelenchus xylophilus) were obtained from DNA extracted directly from wood pieces collected from wilted pine trees throughout the Kyushu and... see more

The toxic and propagation effects on Bursaphelenchus xylophilus of 28 Thymus vulgaris red oil and white oil compounds were examined using direct contact and cotton ball bioassays. Results were compared with those of the trunk-injection nematicides emmamec... see more

The nematicidal activity of two cassia, Cinnamomum cassia, oils (Especial and true), four cinnamon, Cinnamomum zeylanicum, oils (technical, #500, bark and green leaf), and their compounds (e.g., trans-cinnamaldehyde and trans-cinnamic acid) toward adult B... see more

Der Kiefernholznematode, Bursaphelenchus xylophilus, ist der schädlichste pflanzenparasitäre Nematode an Bäumen in Asien und Europa und führt bei anfälligen Koniferenarten, hauptsächlich Pinus spp., zur sogenannten Kiefernwelkekrankheit. Die Krankheit ist... see more

Das Forstquarantänelabor des Julius Kühn-Instituts in Braunschweig (Deutschland) kuratiert eine einzigartige Sammlung lebender Bursaphelenchus-Arten, zudem Dauer­präparate und ITS-RFLP Muster dieser Arten. Die Sammlung wurde von Dr. Helen Braasch gegründe... see more
