| 中文摘要: |
| 为明确四川省茂县花椒根结线虫的种类，通过根结线虫雌虫和2龄幼虫的形态特征及雌成虫的会阴花纹、雌虫酯酶同工酶及分子生物学检测（rDNA-ITS区和rRNA-IGS区），对花椒根结线虫进行了种类鉴定。三种方法的结果均表明在茂县地区花椒上发现的根结线虫为北方根结线虫（Meloidogynehapla），这是我国首次报道在花椒上发现北方根结线虫病，四川省是北方根结线虫新的分布区。 |
| 英文摘要: |
| To confirm the nematode species observed on the pepper Zanthoxylum bungeanum in Mao County, Sichuan Province, an investigation was performed in this region from April to September in 2011. Morphological test (perineal patterns and second stage juveniles), biochemical study (esterase isozyme) and molecular characterization (rDNA-ITS and rDNA-IGS) were used to identify the species. The results showed that the pepper root knot nematode belonged to Meloidogyne hapla Chitwood. This is the first report of M. hapla on Z. bungeanum in China and its occurrence in Sichuan Province. |
