Hoplolaimidae, with more than 420 species, is one of the largest most common families of the infraorder Tylenchomorpha. During a study that was conducted to identify plant-parasitic nematodes in rangelands and forests of Kerman province from 2019 to 2023, nine species of Hoplolaimidae, including Hoplolaimus indicus, Rotylenchus glabratus, Helicotylenchus minzi, H. exallus, H. vulgaris, H. digonicus, H. pseudorobustus, H. digitiformis and H. abunaamai were extracted and identified from 213 soil and root samples of various plants. Hoplolaimus indicus and R. glabratus were found only in one sample of oregano and reed plants, respectively, in the south of Kerman. Among Helicotylenchus species, H. exallus with 5.6% (12 samples, including pine, meadow-grass, Cynodon dactylon, reed, oregano, licorice, tamarix, horsetail and poplar) and H. minzi with a frequency of 5.1% (11 samples, including meadow-grass, reed, spiny rush, Cynodon dactylon, phalaris and oregano) were the most aboundant species. Helicotylenchus vulgaris occurred in five samples of poplar, autumn crocus, Poa and meadow-grass, H. digonicus in five artemisia and meadow-grass samples, 2.4% of samples each, H. pseudorobustus in 1.9% of samples, including four willow and meadow-grass samples, H. digitiformis in one pine sample and H. abunaamai in one spiny rush sample. This study showed that the Helicotylenchus species diversity is greater in the northern and mountainous areas of Kerman province with diverse vegetation, higher rainfall and cooler climate than in the other localities, and that the nematodes were mainly found in the rhizosphere of Poaceae, especially meadow-grass, Cynodon dactylon, as in pine, willow and poplar. |
