Distribution:

Commonly occurring in most soils.

Economic Importance:

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

Back to Top

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.
