摘　　要：宁波口岸从来自日本的山茶属植物及罗汉松中截获一种根结线虫,经形态鉴定和序列分析,鉴定为山茶根结线虫。该线虫雌虫会阴花纹呈星形,条纹粗绳状,2龄幼虫尾末端钝圆,透明区短,较容易与所有其他根结线虫属线虫区分。这是我国口岸首次截获山茶根结线虫,该线虫目前尚未在我国发生,罗汉松可能为其新纪录寄主。A Meloidogyne population was intercepted in Uamelltae sp. ana roaocarpua mucruFny,,.o r＂ Ningbo port. It was identified as Meloidogyne camelliae by morphological characters, morphometrics and molecurlar data based on sequences analysis. M. camelliae is easily distinguished from other species of the genus by its star- like perineal pattem and very coarse striae, the tail of second stage larva bluntly rounded with very short hyaline tail terminus. This is the first report of its interception in China and this species has not been found in China. Podocarpus macrophyllus is a new host to M. camelliae.
