Abstract:

The migration ability of B. xylophilus and B. mucronatus in Pinus thunbergii shoot sections was investigated with artificial inoculation. Compared with B. mucronatus, B. xylophilus passed through a shoot section of P. thunbergii with a higher speed and more population numbers of passing through shoot section. B. xylophilus had stronger reproduction capacity than that of B. mucronatus in the shoot section in 20 days However,the strain Bmo3 of B. mucronatus showed higher migration ability than some strains of B. xylophilus. It is concluded that the cellulase, the time and the numbers of passing through shoot section and multiplication should be taken into consideration for the virulence assessment of B. xylophilus and B. mucronatus.

Key words: Bursaphelenchus xylophilus, Bursaphelenchus mucronatus, migration, multiplication
