Important
Notice:
Only
plant nematode pests which currently are or could potentially be APHIS
quarantine pests are considered for the nematode pest list. According to
the definition reported in the International Plant Protection Convention
(IPPC)'s 2002 edition of Glossary of Phytosanitary Terms [International
Standards for Phytosanitary Measures (ISPM) Pub. No. 5, FAO, Rome; available
online], a "quarantine pest" is "a pest of potential economic importance
to the area endangered thereby and not yet present there, or present but
not widely distributed and being officially controlled". Examples of nematode
quarantine pests that are present in the U.S. but not widely distributed
and being officially controlled or restricted are the golden nematode,
Globodera rostochiensis and the citrus race of the burrowing nematode,
Radopholus similis. The IPPC definition of a quarantine pest is
not applicable to many economically important plant nematode pests in the
U.S., such as Meloidogyne chitwoodi, Ditylenchus destructor,
Heterodera glycines, Meloidogyne naasi, Rotylenchus reniformis,
etc. because they are widely distributed in the U.S. and are not officially
controlled or restricted in their movement. These widely distributed economically
important nematodes are therefore not included in the list.
