Wood-decay fungi, Pleurotus ostreatus, Lentinula edodes, Neolentinus lepideus, Trichaptum abietinum and Cryptoporus volvatus, were tested for their ability to affect the pinewood nematode population in wood by inoculation experiments. Logs of 1m long and branches of 30cm long, cut from healthy pine trees, were inoculated with P. ostreatus and the pinewood nematode. After inoculation, increases in nematode population in wood were compared with those in logs and branches which were inoculated with nematodes alone. Population in wood inoculated with the fungus was significantly less than that in wood without fungus inoculation. Throughout inoculation experiments of other wooddecay fungi, it was demonstrated that L. edodes, N lepideus and T abietinum also showed their ability to control nematode population in wood. C. volvatus were not recognized for their ability to control the nematode population in wood. Inoculation of P. ostreatus and L. edodes to branches cut from dead pine trees killed by the pinewood nematode did not cause decrease in nematode population in dead wood. Fungi might be unable to grow in dead wood because of lack of food resources, such as parenchyma cells which had been destroyed by the pinewood nematode. Jpn. J. Nematol. 35 (2), 63-70 (2005).

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).
