A number of various species of blue-stain fungi were isolated from Tomicus piniperda adults at various stages of development, as well as from the galleries, pupal chambers and sapwood underneath galleries on Japanese red pine. This study was an attempt to identify the species, composition of blue-stain fungi associated with T. Piniperda, the frequency of occurrence of the fungi, and their role in the sapwood-staining of Japanese red pine in Tsukuba City, central Japan. Among the seven species of blue-stain fungi isolated, an undescribed species of Ophiostoma together with O. minus were the dominant species and closely associated with T. piniperda. These two species occurred on newly emerging adults more frequently than the overwintered adults. Hormonema dematioides was also associated with the beetle, however, its frequency of occurrence from the emerged new adults was very low. Although the two other species. O. ips and Graphium sp. were also isolated from emerged beetles, the frequency of these fungi from gallery systems suggested that they were accidentally carried by T. piniperda. Leptographium wingfieldii, known to be associated with the beetle in Europe, was also isolated at a very low frequency and the fungus seemed not to be closely associated with the beetle. Ophiostoma sp. and O. minus appear to be the most important causes of blue-stain of Japanese red pine sapwood after infestation by T. piniperda.
