Abstract A survey of virus vector nematodes based on a total
of 320 published and recent records revealed that 3
Longidorus, 1
Paralongidorus, 6
Xiphinema, 2
Trichodorus, and 3
Paratrichodorus species are present in New Zealand.
Xiphinema
diversicaudatum and
Paratrichodorus minor are the most common
and widespread species.
Longidorus orongorongensis, an undescribed
Paralongidorus species and
Trichodorus cottieri appear to be
endemic species, and
Longidorus taniwha,
Paratrichodorus lobatus
and probably one (still unidentified) species of the
X. americanum group
are also indigenous to New Zealand. Most of the other species (e.g.
Longidorus elongatus,
X. diversicaudatum, and
Trichodorus
primitivus) were probably introduced from Europe. Maps showing the
distribution of the 15 species in New Zealand, and illustrations and tables of
the morphological characters for species identification, are presented. Several
species are of economic importance through direct damage they cause to
cultivated plants, and all can be considered potential vectors of plant
viruses.
