    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.
