Identification of Bursaphelenchus spp. isolated from Chinese packaging wood imported to Austria

Identification of Bursaphelenchus spp. isolated from Chinese packaging wood imported to Austria AbstractBursaphelenchus spp. found in packaging wood (pallets, crates, dunnage)imported with other goods from China to Austria in 1999 were identified, andtheir possible vector species of wood- and bark-breeding insects wererecorded. Of the inspected consignments of coniferous and deciduous wood, 43(78%) were either contaminated with insects or nematodes or showed grubholesor galleries of wood- and bark-breeding insects. Of the 33 samples ofconiferous packaging wood with symptoms of insect attack, 48.5% had beenattacked by longhorn beetles (Cerambycidae), with 11 samples harbouringliving stages of Monochamus, the vector of Bursaphelenchus xylophilus and B.mucronatus. Living stages of non-European Scolytidae, possibly vectors ofother Bursaphelenchus spp., were found in seven samples. Nematodes werefound in 24 consignments, of which nine (=27% of the 33 coniferous woodsamples) were contaminated with Bursaphelenchus spp. Seven samples containedB. mucronatus (East Asian genotype), whereas B. thailandae and B. aberranswere each found in two samples which were also contaminated with B.mucronatus.

Abstract

AbstractBursaphelenchus spp. found in packaging wood (pallets, crates, dunnage)imported with other goods from China to Austria in 1999 were identified, andtheir possible vector species of wood- and bark-breeding insects wererecorded. Of the inspected consignments of coniferous and deciduous wood, 43(78%) were either contaminated with insects or nematodes or showed grubholesor galleries of wood- and bark-breeding insects. Of the 33 samples ofconiferous packaging wood with symptoms of insect attack, 48.5% had beenattacked by longhorn beetles (Cerambycidae), with 11 samples harbouringliving stages of Monochamus, the vector of Bursaphelenchus xylophilus and B.mucronatus. Living stages of non-European Scolytidae, possibly vectors ofother Bursaphelenchus spp., were found in seven samples. Nematodes werefound in 24 consignments, of which nine (=27% of the 33 coniferous woodsamples) were contaminated with Bursaphelenchus spp. Seven samples containedB. mucronatus (East Asian genotype), whereas B. thailandae and B. aberranswere each found in two samples which were also contaminated with B.mucronatus. Morphological features and measurements for the three speciesfound and ITS-RFLP patterns for B. thailandae and B. mucronatus arepresented. Bursaphelenchus thailandae and B. aberrans were found for thefirst time in wood transported over long distances. Bursaphelenchusthailandae is recorded for the first time from China and its ITS-RFLPprofile, enabling differentiation of the species from 17 otherBursaphelenchus spp., is presented.
