Light micrographs of Bursaphelenchus fungivorus. A: Male total body; B: Female anterior region; C: Female tail; D: Vulval region; E: Lateral view of male tail; F: Ventral view of male tail (Scale bar A = 100 μm; B-F = 20 μm).

Figure 2:
Phylogenetic relationships of species belonging to fungivorus-group based on ITS locus. The tree was inferred using GTR + I + G as nucleotide substitution model, tested with 1,000 bootstrap replicates and Bursaphelenchus cocophilus was chosen as outgroup species. Nodes were annotated with NJ and ML bootstrap values, respectively.
