According to the EPPO (European Plant Protection Organization), the pinewood nematode (PWN), Bursaphelenchus xylophilus is a quarantine organism (European Union - directive 2000/29/EC), at the top of the list of the pathogenic species (A1). PWN may be found in North America (Canada, USA and Mexico) and in East Asia (Japan, Korea, China and Taiwan) and has a highly destructive capability towards conifers, in a relatively short time, causing serious economic damage in Japan, China and Korea. This nematode surveying is extremely important and a correct identification of nematode species associated with conifers is essential. Several conifers species are very susceptible (Pinus sylvestris, Pinus nigra and Pinus pinaster), the last one (maritime pine) is a particulary important economic specie in Portugal, and in southern Europe.

In 1999, this nematode was found and identified for the first time in Portugal and in Europe (Mota et al., 1999 ). During 1999 and 2000, the Portuguese government, following an alert provided to European Community officials initiated an extensive national survey; as a result, the nematode was confirmed to be confined to a 30 km radius area in the Setúbal region, near Lisbon. During 2000 and 2001, research has been carried out regarding the morphobiometric as well as molecular (DNA: ITS-RFLP) characterization of the collected populations, as well as closely related species of Bursaphelenchus.

The resulting information is in the process of being published and also compiled for an informative CD-ROM. The time has come for a gathering of scientists conducting research in this critical forest protection area. That is the purpose of the 2001 “International workshop on the pinewood nematode, Bursaphelenchus xylophilus”, to be held in Évora, from Aug. 20-22. I would like to wellcome all participants for this important meeting.
