Nematodes are important soil organisms that constitute a key component of the soil ecosystem. A plant-parasitic survey was conducted to identify the diversity of nematodes associated with two endemic tea plants, honeybush ( spp.) and rooibos () in the Western Cape province of South Africa. A total of 20 farmlands were surveyed and soil samples were collected from the rhizosphere of plants, for nematode isolation and identification based on morphological characters. Confirmation of the species of plant-parasitic nematodes was done using molecular-based tools. Nematodes were classified into various feeding groups based on their colonizer-persister (c-p) values. Plant-feeding nematodes identified from the honeybush tea plants include; , , , and , while sp., and were pathogenic on the rooibos monocultures. Bacterial and fungal feeders ( and ) were also abundant and frequently encountered in all samples. The study provides information on the diversity of nematodes associated with the indigenous herbal tea plants of South Africa.
线虫是重要的土壤生物，是土壤生态系统的关键组成部分。开展了一项植物寄生线虫调查，以确定与南非西开普省两种本土茶树、蜜 bush（ spp.）和路易波士茶（）相关的线虫多样性。共调查了20个农田，并从植物根际采集土壤样本，以便根据形态特征对线虫进行分离和鉴定。使用基于分子的工具对植物寄生线虫的种类进行确认。根据定居者-持久者（c-p）值，线虫被分为不同的取食类群。从蜜 bush 茶植物中鉴定出的植物取食线虫包括； 、 、 和 ，而 sp.、 和 对路易波士单一栽培作物具有致病性。细菌取食者和真菌取食者（ 和 ）在所有样本中也很丰富且经常出现。该研究提供了与南非本土草本茶植物相关的线虫多样性信息。
