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).
