First report of Mesocriconema sphaerocephalum (Taylor, 1936) Loof, 1989 associated with carrot (Daucus carota subsp. Stativus) in Vietnam

, 1989 on carrot in Hanoi city and Hai Duong province in Vietnam. Mesocriconema sphaerocephalum was found on 10% of 130 soil samples. Density of this nematode was up to 45 individuals/250 g soil. To our knowledge, this is the first report of M. sphaerocephalum on carrot. Materials and methods Nematodes were extracted from soil samples using modified Baermann tray method (Whitehead and Hemming, 1965). For morphological characterizations, permanent slides of nematodes were observed through the Carl

COMMUNITY PARTICIPATION FOR DEVELOPING RURAL TRANSPORT INFRASTRUCTURE IN DONG NAI PROVINCE, VIETNAM

Developing countries are facing sustainability problems in developing rural transport infrastructure; the problems arise from the lack of financial resource and public support. Enhancing community participation promises to resolve these challenges. Demographics has a strong influence on community participation; however, how demographic characteristics interact with community participation has been yet to be focally studied. Dong Nai, a southern province in Vietnam, was selected as the case

Morphological and molecular characterization of Epidorylaimus procerus sp. n. (Dorylaimida: Qudsianematidae) from Vietnam

of the nearly cosmopolitan distribution of the genus, none of its species was hitherto recorded in Vietnam. However, a nematological survey conducted to study nematode fauna associated with natural habitats in the country located an interesting Epidorylaimus species. Its study revealed that it belonged to an unknown species that is hereunder described. Materials and methods Nematode extraction and processing Soil samples were collected in Cao Bang Province, a natural area of Northern Vietnam

Morphological and Molecular Characteristics of Pratylenchus haiduongensis sp. n., a New Species of Root–Lesion Nematodes Associated with Carrot in Vietnam

Abstract: Pratylenchus haiduongensis sp. n. is described as associated with carrot (Daucus carota subsp. sativus (Hoffm.) Sch€ubl. & G. Martens) in Hai Duong Province, Vietnam. P. haiduongensis sp. n. is characterized by the lip region with three annuli and slightly separated from the body. Stylet knobs are rounded (never indented anteriorly). The lateral field includes four incisures, bearing areolation at the pharynx region and tail region and occasionally appears in the vulval

Thanks to these valuable properties, turmeric is widely cultivated in many regions in Vietnam, such as Lao Cai, Lang Son, Vinh Phuc, Hung Yen, Nghe An, and the Central Highlands, where it represents a crop of high economic significance to farmers

First morphological and molecular identification of third-stage larvae of Anisakis typica (Nematoda: Anisakidae) from marine fishes in Vietnamese water

(Farjallah et al., 2008). Recent studies indicated morphological differences between Anisakis species (Chen and Shih, 2015; Sonko et al., 2019; Tunya et al., 2020). In addition, molecular tools allow the accurate identification of anisakid larvae by using sequences of the internal transcribed spacer (ITS) region of ribosomal DNA (D’amelio et al., 2010; Mattiucci and Nascetti, 2008). In Vietnam, data on Anisakis nematodes are scarce. There have been a few reports on Anisakis larvae without morphological

Description of Geocenamus vietnamensis sp. n. (Nematoda: Merliniidae) from Vietnam

). Therefore, Sturhan (2012) agreed with Brzeski (1991) in synonymizing Scutylenchus with the “senior” genus Geocenamus, but he considered Merlinius as a valid genus. Following the classification of Sturhan (2012), this study provides morphological and molecular characterizations of a new species of the genus Geocenamus in Vietnam. Materials and methods Nematode population sampling Soil and root samples were collected from the rhizosphere of Casuarina equisetifolia (Casuarinaceae) in Quang Nam province

First report and new molecular and morphological characterizations of root-knot nematode, Meloidogyne javanica, infecting ginger and long coriander in Vietnam

seems to be the most frequently reported nematode associated with ginger (Myers et al., 2017). Especially, Meloidogyne javanica has been found associated with ginger in several countries, including the United States, India, and Brazil (Baptista Dos Santos and Lazaro Lozano, 1993; Hajihassani et al., 2019; Singh and Gupta, 2011). However, only M. incognita has been reported on long coriander (Eryngium foetidum L.) in India (Sheela et al., 2003). In Vietnam, M. javanica has been identified based on

First report of Longidorus mindanaoensis Coomans, De Ley, Jimenez and De Ley, 2012 (Nematoda: Longidoridae) From a Mangrove Forest in Vietnam

Longidorus spp. (needle nematodes) are migratory ectoparasitic nematodes. Besides their direct damages by direct feeding from root cells, some species could also transmit plant pathogenic viruses (Taylor and Brown, 1997). Currently, only one valid species (Longidorus elongatus (de Man, 1876) Micoletzky, 1927) has been reported in association with peanut (Arachis hypogaea L.) from Vietnam. During this study, a population of the genus Longidorus was recovered from saline sea sediments in a

First report of Xiphinema hunaniense Wang & Wu, 1992 (Nematoda: Longidoridae) in Vietnam

overlapping morphometrics of some species groups in the genus Xiphinema make quarantine regulations and protection methods more difficult. Therefore, accurate identification of Xiphinema species using integrate approach is strongly recommended to create a basis for plant pest management. In Vietnam, eight species of the genus Xiphinema have been reported, however, molecular identification are not available for most of them (Nguyen and Nguyen, 2000), and thus, a higher diversity of Xiphinema spp. is

First report of Hemicriconemoides litchi associated with Piper sarmentosum and revision of the genus Hemicriconemoides in Vietnam

The sheathoid nematodes, Hemicriconemoides (Chitwood and Birchfield, 1957), are root-ectoparasitic nematodes that cause damage to various crops (Sikora et al., 2018) with 54 valid species worldwide (Maria et al., 2018). In Vietnam, five Hemicriconemoides species have been reported including H. litchi (Misra and Edward, 1963), H. mangiferae (Siddiqi, 1961), H. cocophilus (Loos, 1949; Chitwood and Birchfield, 1957), H. microdoratus (Dasgupta et al., 1969), and H. brachyurus (Loos, 1949; Chitwood

High-Throughput Sequencing Analysis of Endophytic Bacteria Diversity in Fruits of White and Red Pitayas from Three Different Origins

Pitaya contains various types of polyphenols, flavonoid and vitamins which are beneficial for health and it is among the most important commercial tropical fruits worldwide. Endophytic bacteria might be beneficial for plant growth and yield. However, bacterial diversity in pitaya is poorly characterized. In this study, fruits of white and red pitayas from three different origins (Thailand, Vietnam and China) were chosen for endophytic bacteria diversity investigation by using Illumina HiSeq
