Transmissibility of Bursaphelenchus xylophilus from wood chips to Pinus seedlings and stumps
Studies were carried out in Germany on the transmissibility of Bursaphelenchus xylophilus (EPPO A1 quarantine pest) from wood chips to Pinus seedlings and stumps. Pine wood chips experimentally contaminated with B. xylophilus were brought into contact with unwounded seedlings of 4-year old Pinus sylvestris, and with stumps either freshly cut or cut two months before the trial. These were left in quarantine boxes for two months under field conditions. Results showed that the nematode could only be extracted from stumps, and only if fresh wounds were present. Nematodes were not found on intact seedlings or on stumps cut two months before the trial. The author concluded that in principle B. xylophilus can be transmitted from contaminated wood chips to freshly wounded stumps.
