Ability of wood-decay fungi to prey on the pinewood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle

抄録

The purpose of the study was to determine the extent and ability of wood-decay fungi to attack and kill the pinewood nematode, Bursaphelenchus xylophilus, and to determine the possibility of fungi that inhabit wood to affect the population dynamics of the pinewood nematode in diseased and dead pine trees. The ability of Pleurotus ostreatus, P. pulmonarius, P. eryngii, Lentinula edodes, Lampteromyces japonicus, Neolentinus lepideus, Trichaptum abietinum, Pholiota nameko and Cryptoporus volvatus to prey on the pinewood nematode was confirmed. Nematodes were inoculated on water agar plates on which a single, sparse fungal colony of one of the basidiomycetous fungus grew. Nematodes were immobilized and killed quickly after being inoculated onto plates of the each of the first five fungal species listed above. The other four species of fungi were less effective in attacking and destroying nematodes. The results of multiplication experiments of the pinewood nematode on a fungal colony grown together with Botrytis cinereaon potato dextrose agar paralleled those of the nematophagous ability of each fungus. Nematodes did not reproduce on the fungal colonies of the five species that rapidly killed the nematodes. Jpn. J. Nematol. 35 (1), 21-30 (2005).
