Classification:

Tylenchida; Tylenchina; Tylenchoidea; Tylenchidae; Tylenchinae
: Tylenchus davainei Bastian, 1865

Synonyms:

Morphology and Anatomy:

Key to the genera of the family Tylenchidae

Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:

Refer to subfamily diagnosis (Tylenchinae).

Economic Importance:

Probably fairly small. Most reports are about occurrence and abundance rather than documenting any effects on growth.

Feeding:

Ectoparasites of plant roots, root hairs, algae, etc.

Yeates et al. (1993a) described Tylenchus as plant feeders (algal, lichen (algal or fungal component), or moss feeders that feed by piercing), or hyphal feeders.

Yeates et al. (1993b): classified Tylenchus spp. as "plant associated", indicating that they were found in the rhizospheres of plants.

Hosts:

Ferris et al. (1996): Tylenchus davainei was not cultivable on the fungus species Rhizoctonia.
