PHYLOGENETIC RELATIONSHIPS (250 words) |
 | Notice that the Phylum Nemata consists of two classes: the Adenophorea (nematodes without phasmids), and the Secernentea (nematodes with phasmids). |
 | Plant parasitic members of the Adenophorea are migratory ectoparasites, while Secernentea can be either migratory or sedentary, and ecto or endoparasitic. |
 | When developing management options, for example, for a newly found migratory ectoparasite in the family Tylenchulidae one should consider that biologically it is likely to be more similar to the sedentary endoparasite Tylenchulus than to other migratory ectoparasites in the family Dolichodoridae. |

 | A subclass of nematodes characterized by reduced or absent caudal papillae and an excretory system lacking lateral canals. |
