Liothrips vaneeckei
Priesner, 1920: 2011
Described originally from Europe in a glasshouse in
the Netherlands
, the Lily Thrips has apparently been widely distributed around the world by the commercial trade in lily bulbs.
Okajima (2006)
recorded the species from Honshu,
Japan
, and provided a detailed illustrated description of the species. It is one of the species with maxillary stylets deeply retracted and close together medially in the head (
Fig. 6
). Antennal segment IV is shorter than in many
Liothrips
species
of similar body size and segment VIII is slightly longer, with VI and VII both constricted basally to a narrow neck (
Fig. 16
). The metanotal reticulation is narrow, almost producing striation (
Fig. 25
), and the pelta is recessed into the second abdominal tergite (
Fig. 35
).
Hodson (1935)
gave a detailed account of the life history of
vaneeckei
, recording substantial aggregations under the scales of commercial lily bulbs, and indicating a possibility that the species may have originated on a native
Lilium
species
around
Oregon
in northwestern
USA
.
Bailey (1939)
reviewed the available information on distributions and the range of
Lilium
species
on which the species had been found, including several orchid species. In
Australia
, it was first recorded by
Malipatil
et al
. (2002)
who also provided further references to published information on biology. However, because this insect lives below ground it is rarely found except on cultivated plants, and as a result there is no information on the potential host range away from commercial plantings. The adults listed below suggest that this species is widespread in eastern
Australia
, presumably living on the subterranean parts of native Australian plants, and that it has been here for many years. This is the first indication that this thrips may have a wider host range away from cultivated plants.
