Efficacy of sulfuryl fluoride against the pinewood nematode, Bursaphelenchus xy...

BACKGROUND: The pinewood nematode (PWN) Bursaphelenchus xylophilus is an important conifer disease worldwide. It is the direct cause of the death of millions of pines in south-east Asia (mainly Japan, China and Korea) and has been established in Portugal since 1999. The phasing out of methyl bromide has created an urgent need for alternative treatment of wood packagingmaterials. The effect of sulfuryl fluoride ...

Livro Verde dos Montados

O Livro Verde dos Montados apresenta diversos objectivos que se interligam: Em primeiro lugar, o Livro Verde pretende reunir e sistematizar, de uma forma simples e acessível ao público, o conhecimento produzido em Portugal pelos investigadores e técnicos de várias instituições de investigação ou de gestão que estudam o Montado. Assume-se como uma oportunidade de caracterizar o sistema tendo em conta as suas vár...

Coniferous bark heat treatment for the elimination of the pinewood nematode

Fungi of Raffaelea genus (Ascomycota: Ophiostomatales) associated to Platypus c...

In the study of the fungi associated to Platypus cylindrus, several fungi were isolated from the insect and its galleries in cork oak, among which three species of Raffaelea. Morphological and cultural characteristics, sensitivity to cycloheximide and genetic variability had been evaluated in a set of isolates of this genus. On this basis R. ambrosiae and R. montetyi were identified and a third taxon segregated...

Species of Bursaphelenchus Fuchs, 1937 (Nematoda: Parasitaphelenchidae) and oth...

Insects associated with maritime pine, Pinus pinaster, in Portugal were collected and screened for the presence of Bursaphelenchus species. Nematodes were identified using Internal Transcribed Spacers-Restriction Fragment Length Polymorphism (ITS-RFLP) analysis of dauer juveniles and morphological identification of adults that developed from dauer juveniles on fungal cultures or on cultures in pine wood segment...

Discovery of PWN in Portugal and in Europe

Pine wood nematode, Bursaphelenchus xylophilus, was first reported for Portugal (and Europe) in 1999. The importance of this discovery and economic impact are discussed. Details on the ongoing research of the nematode and its vector, Monochamus galloprovincialis, are provided, and are mainly on the morphology and molecular biology of the nematode and the bioecology of the vector and its relationship with B. xyl...
