Studies on Bursaphelenchus xylophilus under European climatic conditions
Studies were carried out in Germany on the pathogenicity of Bursaphelenchus xylophilus (EPPO A1 quarantine pest) to various hosts under European weather conditions. Tests were carried out in 1993-95 with seedlings of various conifer species (Pinus sylvestris, Picea abies, P. sitchensis, Larix decidua, Pseudotsuga menziesii, Tsuga heterophylla, Abies grandis), which were artificially inoculated with the North American r form and the m form of B. xylophilus. The inoculated plants were placed outdoor in quarantine boxes. Results showed that B. xylophilus could cause wilting symptoms and seedling mortality under European weather conditions, and that the nematode populations could develop with variations according to the host plant and the nematode form inoculated.
