宁波口岸在进境木质包装检疫中经常截获食菌伞滑刃线虫和阿苏里伞滑刃线虫,这2种线虫都属于fungivorus组,形态上十分近似。主要区别在于:前者唇区缢缩十分明显,而后者缢缩不明显;前者排泄孔与半月体平均距离较远(约11μm),而后者较近(约5μm);前者雄虫热杀死后尾部强烈向腹面弯曲(超过180°),后者尾部略腹弯(约90°);前者基顶与喙突相距约9.8μm,喙突高约2.7～3.5μm,后者则分别为8.4μm和1.5～2.8μm;前者雌虫尾多数腹弯十分明显,尾较短(长约50μm),后者尾一般略腹弯(长约68μm)。此外,ITS区的PCR-RFLP方法可区分上述2种线虫。
Ningbo port often in the quarantine of imported wooden intercepting Bursaphelenchus and Bursaphelenchus spp., The two nematodes are fungivorus group, the morphology is very similar. The main difference is: the former lip area constriction is very obvious, while the latter constriction is not obvious; the former excretion hole and the semilunar body distance is far (about 11μm), while the latter closer (about 5μm); the former male heat killed The tail was strongly flexed to the ventral surface (more than 180 °) and slightly caudomedical (about 90 °) caudal to the ventral surface. The former was 9.8 μm apart from the coracoid process and 2.7-3.5 μm in the coracoid, while the latter was 8.4 μm And 1.5-2.8μm. The former had the most obvious abdominal pachycenses and the shorter ones (about 50μm in length), while the latter ones usually slightly pectinate (about 68μm in length). In addition, the PCR-RFLP method in the ITS region distinguishes the above two species of nematodes.
