“…Additionally, nematodes such as Aphelenchoides limberi, A. daubichaensis, A. delhiensis, A. confusus, A. rutgersi, D. dipsaci, P. thornei, and P. neglectus have been detected in canola fields in several countries [5,9]. Growth anomalies and damage have been reported in canola seedlings due to D. dipsaci feeding [29]. On the contrary, symptoms like plant damage caused by nematodes were not observed in the canola fields surveyed in this study in Tekirdağ.…”

Soils collected from 28 canola fields in Malkara, Süleymanpaşa, Muratlı, Hayrabolu, and Ergene districts of Tekirdağ were examined for the determination of nematode fauna. In the soils taken from 0-60 cm depth in each field, 28 genera of nematodes were recovered by the modified Baermann Funnel method. Of these, eight were bacterivores, three were fungivores, five were omnivores, three were predators, and the rest were plant-parasitic species. Nematodes in survey areas had colonizer-persister values ranging from 1 to 5. The maturity and community indices were also calculated and four were found as follows: Enrichment (E): 34.6±15.2; Maturity (MI): 2.68±0.05; Plant parasite (PPI): 2.69±0.39; Shannon's diversity (H'): 1.80±0.26. The predominant taxa were Filenchus (100%), Mesodorylaimus (92%), and Ditylenchus (85.1%). In terms of density in 100 cm3 soil, the highest values were found in the genus Acrobeloides (192 individuals/100 cm3 soil), and the number of Ditylenchus (57 individuals/100 cm3 soil), Filenchus (180 individuals/100 cm3 soil), and Mesodorylaimus (165 individuals/100 cm3 soil), individuals were also found high in some soils. The plant parasitic nematodes identified in canola fields include Boleodorus tylactus, Filenchus cylindricus, Filenchus sheri, Filenchus thornei, Geocenamus brevidens, Helicotylenchus digonicus, Malenchus fusiformis, Paratylenchus variabilis, Pratylenchoides alkani, Rotylenchus robustus, Tylenchorhynchus annulatus, and Tylenchorhynchus cylindricus.

“…There are limited studies on nematode diversity associated with canola in a limited number of countries and Türkiye as well [29,9]. Therefore a study in canola fields in Tekirdağ is planned.…”

Plant‐parasitic nematodes of potential phytosanitary importance, their main hosts and reported yield losses

2013

View full text Add to dashboard Cite

The potential phytosanitary importance of all named plant‐parasitic nematode species was determined by evaluating available information on species characteristics, association with economically‐important crop hosts, and ability to act as vectors of viruses or form disease complexes with other pathogens. Most named species of plant‐parasitic nematodes (PPN) are poorly known, recorded from a single location only, not associated with economically‐important crops, and not known to be associated with other plant disease organisms. However, 250 species from 43 genera fulfilled one or more of the criteria to be considered to present a phytosanitary risk. The genera and number of species (in parentheses) considered as posing phytosanitary risk included: Achlysiella (1), Anguina (8), Aphasmatylenchus (1), Aphelenchoides (12), Aphelenchus (1), Belonolaimus (2), Bitylenchus (3), Bursaphelenchus (4), Cactodera (3), Ditylenchus (8), Dolichodorus (1), Globodera (3), Helicotylenchus (7), Hemicriconemoides (3), Hemicycliophora (3), Heterodera (25), Hirschmanniella (5), Hoplolaimus (5), Ibipora (3), Longidorus (10), Macroposthonia (2), Meloidogyne (38), Merlinius (3), Nacobbus (1), Neodolichodorus (2), Paralongidorus (2), Paratrichodorus (11), Paratylenchus (3), Pratylenchus (24), Punctodera (3), Quinisulcius (3), Radopholus (5), Rotylenchulus (3), Rotylenchus (1), Scutellonema (5), Sphaeronema (1), Subanguina (3), Trichodorus (5), Tylenchorhynchus (8), Tylenchulus (2), Vittatidera (1), Xiphinema (15) and Zygotylenchus (1). For each of the 250 species main hosts and yield loss estimates are provided with an extensive bibliography. Of the 250 species, only 126 species from 33 genera are currently listed as regulated pests in one or more countries worldwide. Almost all of these 250 species were also associated with economically important crops and some also acted as vectors for viruses.
