“…In this study, 12 ophiostomatoid fungi were found in galleries of Scots pine infested by T. piniperda. A similar spectrum of ophiostomatoid fungi has been found associated with T. piniperda in other parts of its distribution range in Europe [6,32,39,40,46,48,50,51]. Recently, some researchers have recorded that the mycobiota of T. piniperda in Asia differ from the European ones [14,17,[25][26][27][28][29][30][31][32][33][34][35][36][37][38]58].…”

-The species composition and virulence of fungi associated with Tomicus piniperda were studied at eight locations in Poland. 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.

“…In Europe, T. piniperda carries numerous species of Ophiostoma and their anamorphs [6,[12][13][14]19, 21, 24, 32, 39, 40,42,46,48,50,51,56], with O. minus and Leptographium wingfieldii being the dominant species. In Poland, there is only one report on fungi associated with T. piniperda.…”

“…In addition, O. minus has been shown as one of the most virulent ophiostomatoid fungi on pines (Masuya et al, 2003). This fungus was associated with an important decline of Pinus sylvestris in France (Piou & Lieutier, 1989) and recently related with important diseases like these caused by Dendroctonus frontalis (the Southern Pine Beetle) in North America (Six & Klepzig, 2004) or by the pine wood nematode pathogen Bursaphelenchus xylophilus (Maehara et al, 2005).…”

Ophiostomatoid fungi associated with declined Pinus pinaster stands in Spain

Aim of study: We studied the presence of fungi and distribution patterns in relation to the health status of declining Pinus pinaster trees.Area of study: Trees in two declining stands in Central Spain were allotted to three declining classes...Material and Methods: Trees in two declining stands in Central Spain were allotted to three declining classes (healthy, declining and recently dead) and 3 trees of each class were felled in each stand. Wood slides (phloem and xylem) were taken at six positions along the trees and samples collected from fungal identification.Main results: A total of 21 fungal taxa were isolated and identified; eleven of these species belonged to the Ophiostomatoid group. Ophiostoma minus was the most frequently isolated fungus and was identified in 22% of the samples, mainly associated to dead and diseased trees.Research highlights: Together these results suggest a putative association of O. minor with the decline in this area, and thus we suggest paying more attention to this fungus as a potential agent of decline in P. pinaster stands.Key words: Ophiostomatoid fungi; forest pathology; bluestain fungi; multivariate analyses.Abbreviations: UTM: Universal Transverse Mercator coordinate system; MEA: Malt Extract Agar; DNA: Deoxyribonucleid acid; ITS: Internal Transcribed Spacer; BLAST: Basic Local Alignment Search Tool; CCA: Canonical Correspondence Analyses; PWN: Pine Wood Nematode.

Fungi were also isolated from endemic populations of lps sexdentatus in the department of the Var in 1987. The growth of the fungi isolated from the Var samples was analysed on malt-agar medium. Their agressiveness was determined after artificial inoculation of Scots pines, by measuring the development of the induced defense reaction (length and resin quantity) and the extension of the fungi within this reaction. The Ophiostomatales associated with I acuminatus in south-eastern France included 4 species that differed greatly from the Scandinavian and German flora associated with the same insect. They also differed from the flora associated with I sexdentatus, even when the 2 beetles occurred in the same trees, and although the 2 fungi (Ophiostoma lps and Ophiostoma brunneo-ciliatum) were both associated with the 2 insect species (
