Abstract

Potential forest pest beetles conveyed to Finland on timber from the Soviet Union.

Abstract

Samples of 14 lots of pine [Pinus sylvestris] pulpwood imported by rail from Russia to Finland in 1985 were examined for the presence of potential forest and timber pest beetles [Coleoptera]. Other tree species that occurred occasionally among pine in some assortments were aspen [Populus tremula], birch [Betula sp.], fir [Abies sp.], larch [Larix sp.] and spruce [Picea sp.]. Seven of the lots originated from the European side of the Ural Mountains and 7 from Siberia. Some 23 species of Scolytidae and about 18 other phloeophagous species were found, including 3 species new to Finland: Phaenops guttulata [Melanophila guttulata], Ips subelongatus and Orthotomicus erosus.
