A New Description of the Process of Identification of Plant-Parasitic Nematode Genera
Accurate identification is a prerequisite to an understanding of the effect of nematodes as parasites of plants. It is obvious that no significant study on plant pests should be initiated until the identity of the parasite has been accurately established. For example, members of the genus Rotylenchulus in the past have been erroneously classified in the genus Helicotylenchus (H. elisensis, H. parvus), or they were proposed as new genera (Spyrotylenchus, Leiperotylenchus). In the first case, potentially dangerous parasites were wrongly identified as members of a relatively innocuous genus. In the second example, costly studies may have been initiated to define the biology of a supposedly new parasite, whereas the biology of Rotylenchulus is well known.
