The Panel on Plant Health performed a pest categorisation of
Nacobbus aberrans
(Nematoda:
Pratylenchidae), the false root-knot nematode, for the EU. The nematode was originally described from
the American continent. Due to differences in host range as well as molecular variability among
populations,
N. aberrans
should be regarded as a species complex (
N. aberrans sensu lato
). All
populations belonging to this species complex are pests of important host plants in the EU.
N. aberrans
had been detected indoors in the EU in the 1950s and 1960s but is no longer reported to
be present in the EU. It is regulated by Council Directive 2000/29/EC, listed in Annex IAI as
N. aberrans
(Thorne) Thorne and Allen. Species within the
N. aberrans
complex are endoparasitic with
migratory and sedentary stages. They are highly polyphagous attacking many plant species. They are
also found in soil where they can survive dry conditions and freezing temperatures. Plants for planting
and soil are potential pathways for this nematode. Climatic conditions in the EU are similar to those
found in the countries where the pest is present. Hosts of the nematode from which high-yield losses
have been reported include potato, sugar beet, tomato and beans. The nematode only moves short
distances (around 1m) but may be spread with plants and soil moving activities. Measures are
available to inhibit EU entry via potatoes and soil as such but not all host plants are covered by current
legislation. Entry of the nematode with plants and soil attached to plants for planting that are not
regulated is therefore possible.
N. aberrans
does satisfy all the criteria that are within the remit of
EFSA to assess to be regarded as a Union quarantine pest. [-]
