The genus Bursaphelenchus Fuchs (Nematoda: Aphelenchida) in north-west Spain

As a consequence of the report of pine wood nematode (Bursaphelenchus xylophilus) in the Setubal peninsula (Portugal), nematodes of the genus Bursaphelenchus and the vector insect were studied in pine forests, timber industries and entry points for imported timber in Galicia (north-west Spain). The aim of this paper was to contribute to the establishment of the necessary measures to prevent the introduction of B. xylophilus into Spain. Sampling, nematode extraction and identification were carried out according to the EU norm. From collections made in 1999-2002, a total of 2612 samples were studied. Bursaphelenchus eggersi, B. mucronatus and B. sexdentati were found, as well as Monochamus galloprovincialis, a vector cerambycid beetle. Bursaphelenchus Xylophilus was not isolated. Morphometric characteristics and geographic distribution of the species are provided and the risk of introducing B. xylophilus to Spain assessed.
