Hosts
Primary hosts are Ribes spp with a range of secondary hosts, including lettuce. This is one of the few aphids that live deep in the leaves towards the heart of the lettuce plant rather than only on the outer leaves.
Distribution
Europe, Asia, North & South America, New Zealand
The species was discovered in Tasmania in 2004 and
spread to southern Victoria in 2005. Monitoring of this species in other parts of
Australia is the principal reason for the development of this key.
Identification
Specimens of this species can be identified using the
characters provided in the key.
Wingless adult females (apterae) have dark transverse
bands on the outer parts of each abdominal segment.
Alatae have the siphunculi dark throughout and this
differentiates the species from other similar aphids included in this key.
Further information is available on the PaDIL website.
