| Abstract: | In 1984 a heavy Bursaphelenchus xylophilus infestation was observed in pinewood chips imported from USA and Canada into Finland. Because there are good reasons to suppose that B. xylophilus, if spread to pine forests in North Europe, can cause significant damage, the import of coniferous wood into Finland has been prohibited since autumn 1984. In surveys B. xylophilus has not been found in roundwood or in chips imported from European countries into Finland. Neither has B. xylophilus been detected in Finnish pine trees around harbours nor in paper mills handling North American wood. |
