Abstract:Sweden requires all coniferous roundwood from countries outside Europe to have been debarked but makes no requirement for European wood. Six shipments of unbarked roundwood of Pinus pinaster from France and 14 shipments of debarked P. radiata logs from Chile were inspected in Sweden during 1988 and 1989. The imported wood from France yielded 92 insect species (90 Coleoptera and 2 Hymenoptera). Seventeen of these species do not occur in Sweden. All six consignments were thoroughly attacked by bark- and wood-boring insects, representing 25 species. The logs from Chile had been well debarked; less than 1% of the inspected logs contained living insects. Nevertheless, a total of 49 insect species (46 Coleoptera, 1 Isoptera, 1 Hymenoptera and 1 Orthoptera) were found in the 14 shipments. Of these species 21 are not indigenous to Sweden.
