Improved morphological key to the species of the xylophilus group of the genus Bursaphelenchus Fuchs, 1937

摘要: Correct identification of the pine wood nematode Bursaphelenchus xylophilus becomes more difficult, as related or similar species are described. Spread is being monitored worldwide, and in view fact that several new have been described, keys should be adjusted accordingly. Based on key group published by Braasch (2008) revised intrageneric grouping et al. (2009), an improved dichotome morphological including newly described (B. paraluxuriosae, B. populi, B. macromucronatus, B. firmae, B. koreanus B. gillanii) presented. The recognition quarantine pest B. xylophilus using characteristics laboratories National Plant Protection Services facilitated a simplified key.
