    Bursaphelenchus Fuchs, 1937 (Nematoda : Parasitaphelenchidae) species associated with Pinus species in northern Turkey
    (Walter De Gruyter Gmbh, 2008) Akbulut, Süleyman; Vieira, Paulo; Ryss, Alexander; Valadas, Vera; Keten, Akif; Mota, Manuel
    A survey for Bursaphelenchus nematodes, associated with different conifer trees, was conducted in several forest areas in the northern regions of Turkey. Only pine trees (Pinus nigra, P. pinaster and P. sylvestris) yielded Bursaphelenchus specimens. Nematodes were identified using several morphological diagnostic characters of the genus (male spicule structure, number of lateral incisures, number and distribution of the male papillae, presence of female vulval flap), and confirmed by using RFLP analysis of the internal transcriber spacer (ITS) regions of ribosomal DNA. Three different species were identified from several sampled areas, namely B. mucronatus, B. pinophilus and B. sexdentati, representing a first report of the last two species for Turkey. The association of B. pinophilus with black pine (P. nigra) is herein reported for the first time.

    Preliminary survey of the pinewood nematode in Turkey
    (2006) Akbulut, Süleyman; Vieira, Paulo; Ryss, Alexander; Yüksel, Beşir; Keten, Akif; Mota, Manuel; Valadas, Vera
    A survey was conducted in the northern conifer forests of Turkey in 2003 and 2004 for the pinewood nematode, Bursaphelenchus xylophilus. Wood samples were collected from declining pine trees, located in the following target areas: Düzce, Ankara, Bolu, and Artvin. Nematodes were extracted from over 310 samples and were observed and identified. B. xylophilus was not detected in any samples. Bursaphelenchus species were only found in 6% of the samples. From the B. xylophilus-group, only the species B. mucronatus was reported. Species identification was performed from morphological characters, particularly male spicules, and by molecular analysis with ITS-RFLP. © The Authors (2006).
