"Six species of nematodes recorded so far to be included in the xylophilus group of the genus Bursaphelenchus (Giblin and Kaya, 1983) are B. abruptus (Giblin-Davis et al., 1993), B. conicaudatus (Kanzaki et al., 2000), B. fraudulentus (Ruhm, 1956), B. kolymensis (Korentchenko, 1980; Magnusson and Kulinich, 1996), B. mucronatus (Mamiya and Enda, 1979), and B. xylophilus Mamiya and Kiyohara, 1972; Nickle, 1970; Steiner and Buhrer, 1934). These species could be identified by some morphological char-acters such as the shapes of spicule, bursa and female tail, and some morphometric values of males and females (Giblin-Davis et al., 1993; Kanzaki et al., 2000). Molecular phylogenetic technique have also been used for this purpose (Kanzaki and Futai, 2002). Among morphologi-cal characters examined are the arrangements of male caudal papillae. For instance, B. onicau-datus, B. fraudulentus and B. kolymensis were reported to have four (2+2) caudal papillae (Kanzaki et al., 2000; orentchenko, 1980; Magnusson and Kulinich, 1996; Ruhm, 1956) and B. abruptus, B. mucronatus, and B. xylophi-lus were seven (2+1+2+2) (Giblin-Davis et al., 1993; Nickle et al., 1981). In this study, we re-examined the arrangement of caudal papillae of B. conicaudatus and B. fraudulentus to ascertain the difference in the number and the arrangements. Then we compared the arrangement of caudal papillae among six Bursaphelenchus species including two species examined to clarify whether the arrangement of caudal papillae could be applied to identification of species in xylophilus group.
