Bursaphelenchus

Fig. 1.5. Delineation of Bursaphelenchus species. (A) Maximum parsimony phylogram of an analysis of the aligned ITS1 and ITS2 regions from Bursaphelenchus isolates. Branch lengths are given above each branch, and bootstrap support below. (B) As for (A) but using NJ analysis (logdet/paralinear distance correction). Adapted from Beckenbach etal. (1999).

Depuration rates of diazinon differed significantly for two species of nematodes, Panagrellus redivivus and Bursaphelenchus xylophilus (Al-Attar and Knowles 1982). Both species showed maximum uptake of radiolabeled diazinon between 6 and 12 h, and both metabolized diazinon to diazoxon and pyrimidinol. By 96 h, 95% of the diazinon in P. redivivus had been metabolized, but only 26% was transformed in B. xylophilus, again demonstrating variability in diazinon metabolism between related species.

Cinnamon oil possessed strong nematicidal activity against the male, female and juveniles of pinewood nematode Bursaphelenchus xylophilus (Park et al., 2005). Cinnamyl acetate, the active ingredient in the oil, at a concentration of 32.81 pg/1 resulted in 50% mortality of nematodes.
