In southern China, the staple food rice () field is commonly rotated with brown mustard . Root-knot nematodes (RKNs) are a major threat to rice production. From 2019 to 2021, in 56 fields from 26 counties in Guangxi Province were observed with symptoms of leaf yellowing, stunting, and several hook-shaped galls on the roots. Females and egg masses of sp. were found within the galls. The females, males, and second-stage juveniles (J2s) were collected, and identified with morphological and molecular characteristics and female perineal patterns. was transplanted in pots and a pathogenicity test was conducted to confirm the species as . In China, this is the first record of a natural infection of mustard with . , and this finding has great importance for Chinese mustard production, since this nematode may damage mustard plants and become an additional problem for this crop.
在中国南方，主食水稻（）田通常与芥菜轮作。根结线虫是水稻生产的主要威胁。2019年至2021年，在广西26个县的56块稻田中观察到叶片发黄、发育不良以及根部有几个钩状虫瘿的症状。在虫瘿内发现了 种的雌虫和卵块。收集了雌虫、雄虫和二期幼虫（J2），并通过形态学、分子特征和雌虫会阴花纹进行鉴定。将其移栽到花盆中进行致病性测试，以确认该物种为 。在中国，这是芥菜自然感染 的首次记录。 ，这一发现对中国芥菜生产具有重要意义，因为这种线虫可能会损害芥菜植株，并成为该作物的另一个问题。
