Taxonomic notes on three Tylenchorhynchus spp. (Nematoda, Telotylenchidae) associated with turfgrass in Korea

Detection of the stunt nematode Tylenchorhynchus annulatus in the rhizosphere of rice and corn in Indonesia

“…The morphometrics of the Indonesian T. annulatus females isolated from corn are, in general, in agreement with the measurements of T. annulatus populations isolated in the USA, Nigeria, Malaysia, South Korea, China and Taiwan (Mizukubo and Toida 1991;Chen et al 2006;Handoo et al 2014;Pham et al 2014;Mwamula et al 2020;Abdulsalam et al 2022). The Indonesian females are somewhat shorter in body length compared with the females from the T. annulatus populations described by Chen et al (2006) 2022) but a shorter female body length was also reported for a T. annulatus population isolated from rice in Malaysia (515-741 µm) (Mizukubo and Toida 1991).…”

Occurrence of Plant-Parasitic Nematodes of Turfgrass in Korea

“…Twenty-eight species/taxa belonging to 16 genera and 12 families of PPNs were identified and described from the 781 sod cores collected from the 13 golf courses distributed across Korea. Comprehensive morphological and molecular characterization of various studied taxa, including new species description were presented in the earlier published articles (Mwamula et al, 2020a(Mwamula et al, , 2020b(Mwamula et al, , 2020c(Mwamula et al, , 2020d. Among the 28 species/taxa identified, 12 species/taxa (Tylenchorhynchus thermophilus, Pratylenchus diversity indices are presented in Table 3.…”

Among the 28 species/taxa identified, 12 species/taxa ( Tylenchorhynchus thermophilus , Pratylenchus zeae , Mesocriconema nebraskense , Mesocriconema sp., Neopsilenchus sp., Hemicycliophora labiata , Helicotylenchus caudatus , Helicotylenchus microlobus , Helicotylenchus asiaticus , Filenchus sp., Meloidogyne graminicola , and Paralongidorus koreanensis ) are reported as new records in Korea.…”

“…Measurements and micrographs were taken using a Zeiss imager Z2 microscope (Carl Zeiss, Gottingen, Germany) fitted with Axio-vision software: Material Science Software for Research and Engineering software (Carl Zeiss). The various promorphs/genera were characterized to species level according to diagnostic criteria using morphological, morphometric and molecular tools as detailed in Mwamula et al (2020 , 2020b , 2020c , 2020d , 2020e , 2020f ). Promorphs were corresponded to the identified species as described by Vandenbossche et al (2011) .…”

“…Thus, correct species identification plus an understanding of their diversity on turfgrass is a prerequisite for a successful nematode control and management strategy. A survey of Korean golf courses in April 2017 to 2019 uncovered several species of various suborders of PPNs; as detailed by Mwamula et al (2020a , 2020b , 2020c , 2020d , 2020e , 2020f ). However, it is evident that little is known about their diversity on turfgrass in Korea.…”
