The fungi were isolated from phloem and sapwood samples taken from insect galleries and then identified. The virulence of the most common ophiostomatoid species was evaluated through inoculations using two-year-old Scots pine seedlings. A great diversity of fungi were found associated with T. piniperda including 4 837 cultures and 67 species. The most important groups of fungi were the ophiostomatoids and moulds including mainly Penicillium Trichoderma and Mucor species. Among ophiostomatoid fungi Ophiostoma minus and O. piceae dominated with a frequency of occurrence of 32.4 and 11.5 of inspected galleries respectively. Occasionally isolated species included Leptographium lundbergii L. procerum L. wingfieldii Graphium pycnocephalum and Graphium sp. W . In general the frequency of the ophiostomatoid species was highly variable among locations. Leptographium wingfieldii and O. minus were the only species capable of killing whole plants and penetrated deeper into the sapwood than other species 87-100 mortality during the 11 week incubation period . Other fungi including O. piliferum O. piceae and L. procerum were considerably less virulent. associated fungi Leptographium Ophiostoma Pinus sylvestris Tomicus piniperda virulence Résumé - Champignons associés à Tomicus piniperda en Pologne et appreciation de leur virulence pour des plants de pin sylvestre.
