See genus description for general configuration.
The only way to differentiate it from T. acutoides is by the absence of males (Tom Powers, UNL).
Common on rangeland grasses in midwest and Rocky mountain areas.
Widely distributed throughout the Great Plains where it is the most common species of the genus.
This species is common in western Nebraska. Its found in cultivated fields and in rangeland. (Tom Powers, UNL)
Tylenchorhynchus acutus reduced growth of crested wheat grasses, Russian wild rye, intermediate wheat grass, and Snake River wheat grass
in clay-sand and sandy loam soils.
Ectoparasite - browses on epidermal cells and root hairs.
Grasses, including crested wheat grasses, Russian wild rye, intermediate wheat grass, and Snake River wheat grass.

Males not required for reproduction.
Reproduction greatest in sandy loam soil.
Pathogenicity was greatest in sandy loam soil.
Some cultivars of the grasses were more tolerant of the nematode damage than others.
