“…Ten species belonging to nine genera, five families, and two orders of plant-parasitic nematodes were found in the rhizosphere of six medicinal plants in Me Linh Station for Biodiversity, and among them, eight species are new records on medicinal plants in Vietnam (Ngo, 2000;Nguyen & Nguyen, 2000;Nguyen et al, 2015). Although plantparasitic nematodes have been reported from many medicinal plants, this study provided nematode component associated with six new hosts in Vietnam (five hosts are new to the world) (Ngo, 2000;Nguyen & Nguyen, 2000;Khanzada et al, 2007;Nguyen et al, 2015;Abtahi & Bakooie, 2017;Eapen & Pandey, 2018).…”

“…Plant-parasitic nematodes are one of the most important pests that are seriously threatening the food security of the world, causing an estimated economic loss of at least 12.3% (157 billion USD) worldwide (Hassan et al, 2013). A number of studies of plant-parasitic nematodes associated with medicinal plants has been executed, and plant-parasitic nematodes are associated with almost all medicinal plants studied to date (Ngo, 2000;Nguyen & Nguyen, 2000;Khanzada et al, 2007;Nguyen et al, 2015;Abtahi & Bakooie, 2017;Eapen & Pandey, 2018). Remarkably, yield losses caused by plant-parasitic nematodes on medicinal plants were up to 30% (Eapen & Pandey, 2018).…”

Plant-parasitic nematodes are known as one of the most important pests attacking various plants in the world, and investigating the nematode component is very essential for management of this pest and prevent damage to plants in general. Our survey of plant-parasitic nematodes on medicinal plants in Melinh Station for Biodiversity, a place for conservation of precious plants and animals in Vietnam, identified ten species that belong to nine genera, five families, and two orders of plant-parasitic nematodes parasitizing six medicinal plants. Excoecaria cochinchinensis was parasitized by the highest number of nematode genera (5 genera, including Xiphinema, Discocriconemella, Meloidogyne, Helicotylenchus, and Hemicriconemoides), while Hymenocallis littoralis was associated with the highest number of plant-parasitic nematodes (2060 nematodes/250g soil). The results also showed that Discocriconemella limitanea was found to be a dominant species with the highest number of individuals on 6 medicinal plants, and the genus Helicotylenchus had the highest frequency of appearance (5/6 plants or 83.3%). These nematodes caused symptoms such as yellowing leaves, root galls, and root lesions, which directly affect the quality and yield of medicinal plants. Based on the results, this study showed that plant-parasitic nematodes are a potential threat to the cultivation of medicinal plants in Melinh Station for Biodiversity, and thus, control measures should be applied to ensure sustainable cultivation of medicinal plants in this place.

“…At the same time, the importance of large‐scale monoculture of medicinal plants in Vietnam has grown massively in the past two decades, bringing with it significant economic benefits for the country as a whole. In addition, previous studies have reported that PPNs can cause serious symptoms in medicinal plants such as yellowing leaves, stunting, galls on leaves and roots and root necrosis, and can cause up to 30% of yield losses to medicinal plants (Abtahi & Bakooie, 2017; Eapen & Pandey, 2018; Gupta & Mondal, 2018; Khanzada et al, 2007). It is now of vital importance that the yield and quality of medicinal plant crops be protected and enhanced by dedicated pest management strategies, which must clearly include provisions for PPNs.…”

Plant‐parasitic nematodes (PPNs) are one of the most damaging pests to plants and are able to cause significant damage to all parts of plants, including stems, leaves, flowers, fruits and roots. Studies on the diversity, host range, distribution and identification methods of PPNs are therefore vital in order to create a basis for management. This current study represents the first dedicated investigation of PPNs from medicinal plants in Vietnam, focusing on the diversity of nematodes associated with 23 different plant species. In combination with a literature review of PPNs in Vietnam, this work has resulted in an updated list of 217 PPN species belonging to 40 genera, 15 families and three orders and also provides a pictorial online key for the identification of 52 most common and important PPN genera of the world. This key is based on the most crucial diagnostic features of PPN females, including female body shape, cuticle, labial shape, cephalic framework, stylet, stylet base, pharynx, median bulb, pharyngeal gland, vulva, tail shape and phasmid. Pictorial representations of these genera and their diagnostic characters are included in the browser‐based key to benefit users from all levels in nematology, be they beginners or experts.
