“…Prior to this work, there have been several research papers illustrating a broad diversity of nematodes associated with turfgrasses in the United States [5,10,11,28,62], Canada [7,63,64], Argentina [65], Germany, Sweden, Norway [66,67], Belgium [8], Israel [68] and Korea [6]. Previous research showed that the species of Hemicriconemoides and Tylenchorynchus associated with turfgrasses include H. chitwoodi Esser, 1960 and H. wessoni Chitwood & Birchfield, 1957 in Cynodon dactylon [10,11]; H. brachyurus (Loos, 1949) Chitwood & Birchfield, 1957 in Poa pratensis and Zoysia japonica [6]; T. claytoni Steiner, 1937 in P. pratensis and Z. japonica [6,10,11]; T. dubius in Agrostis stolonifera and P. pratensis [69]; T. annulatus in Z. japonica; and T. thermophilus in Z. japonica and P. pratensis [6]. The work presented here provides new records of H. rosae and T. leviterminalis associated with turfgrasses.…”

“…Several surveys of nematodes associated with turfgrasses have been conducted in the USA and other countries, and have shown a broad diversity with different countries and regions [5][6][7][8][9][10][11]. In Florida, USA, common genera of nematodes that damage turf include ectoparasitic Belonolaimus, Trichodorus, Nanidorus, Helicotylenchus and Mesocriconema, and endoparasitic Hoplolaimus and Meloidogyne [5].…”

“…In Florida, USA, common genera of nematodes that damage turf include ectoparasitic Belonolaimus, Trichodorus, Nanidorus, Helicotylenchus and Mesocriconema, and endoparasitic Hoplolaimus and Meloidogyne [5]. A total of 29 species belonging to 22 genera in 15 families in North Carolina (NC) and South Carolina (SC), USA [10]; 28 species/taxa belonging to 16 genera and 12 families in Korea [6]; 52 different species/taxa belonging to 23 genera and 9 families in Belgium [8]; and 9 genera of plant-parasitic nematodes associated with turfgrass in southern Ontario, Canada [9] were reported. The nematodes associated with turfgrasses in NC and SC were molecularly characterized using 18S rDNA sequences [12].…”

The turfgrass industry has undergone a rapid development in Guangdong province, China, which has the largest number of golf courses in the country. Recent surveys of turfgrasses in the province revealed five plant-parasitic nematodes that are prevalent: Helicotylenchus dihystera, Mesocriconema xenoplax, Meloidogyne graminis, Hemicriconemoides rosae and Tylenchorhynchus leviterminalis. The most prevalent species are M. xenoplax and M. graminis, found in 60.6% and 27.3% of locations, respectively. These five species are morphologically and morphometrically described. Molecular characterization and phylogenetic analyses using 18S rRNA and the D2-D3 expansion segments of 28S rRNA sequences are provided. This is the first report on molecular characterization and phylogenetic relationships of plant-parasitic nematodes associated with turfgrasses in Guangdong, China. This work was a first step for future study including pathogenicity assay, relationship examination with other pathogens and development of control measures of these turf nematodes to provide more precise and effective management options to turf superintendents.

Background The nematodes of the genus Helicotylenchus are root parasites of a wide variety of plants, and certain species can cause serious damage to their hosts. During a survey of the plant-parasitic nematode associated with tomato, a population of Helicotylenchus was collected from tomato roots and soil samples. Thus, one of the objectives of the study was to confirm the specie of Helicotylenchus obtained from the tomato samples based on morphological and molecular characteristics. In addition, a mass pure culture of plant-parasitic nematodes is key to pathogenicity studies and many other biological studies. However, a successful mass rearing method for Helicotylenchus has not been reported. Thus, the other objective of the study was to establish a method of culturing Helicotylenchus. Results Based on both the morphological characteristics and molecular analysis of the internal transcribed spacer (ITS) and D2-D3 expansion region of 28S ribosomal RNA (rRNA) sequences the specimens were identified as Helicotylenchus microlobus. Phylogenetic analysis with the rRNA sequences of the ITS and 28S D2-D3 regions was consistent with molecular identification, suggesting this population formed a highly supported clade with other H. microlobus populations. Additionally, a method for culture of H. microlobus on carrot disks was established, and the effect of temperature on the reproduction rate (Rr) of H. microlobus was investigated. The optimum temperature for culturing H. microlobus on carrot disks was 27.5 °C and, after inoculation with 30 females of H. microlobus at 27.5 °C for 90 days, Rr reached 406. Conclusions To our knowledge, this is the first detailed description of H. microlobus from tomato in China. This study also demonstrated that the carrot disk method is suitable for the culture of H. microlobus. This study lays a foundation for other related research on H. microlobus, and has significance for the study of Helicotylenchus.

“…Helicotylenchus pseudorobustus and Meloidogyne naasi were the most prevalent nematodes. Twenty-eight species/taxa belonging to 16 genera in 12 families of PPNs were found at 13 golf courses in Korea [ 11 ], with Helicotylenchus microlobus , Mesocriconema nebraskense , Tylenchorhynchus claytoni , Mesocriconema sp., and Meloidogyne graminicola the most prevalent species in all management zones [ 11 ]. Twenty-three nematode genera are known to be associated with turfgrasses in Australia [ 12 ].…”

We sampled 127 turfgrass soil samples from 33 golf courses in NC, EC, and SC for plant-parasitic nematodes (PPNs). PPNs were extracted from soil samples using the shallow dish method and were identified at the genus or species levels with a combination of morphological and molecular methods. The results revealed 41 species of nematode belonging to 20 genera and 10 families. Nine genera are new records of PPNs associated with turfgrass in China. The PPNs show strong geographical distributions. Of the 20 genera, Helicotylenchus, Paratrichodorus, Hoplolaimus, Meloidogyne, Hemicriconemoides, and Mesocriconema showed higher infestation and frequency, and most of these genera had numbers in soil samples above established damage thresholds. Four golf courses had soil samples with PPNs > 30%, indicating the potential for nematode damage. The biodiversity indices H’, SR, J’, λ, and H2 showed significant differences among different regions and turfgrass species; H’, SR, J’, and H2 were significantly higher in EC than in NC and SC, while λ was lowest in EC. Creeping bentgrass had the highest H’, SR, J’, and H2 and the lowest λ in comparison with seashore paspalum and hybrid bermudagrass. These findings provide baseline information on the occurrence of turfgrass-associated PPNs in China, and have important implications for the effective management of PPNs causing damage on turfgrass.
