Schedotrioza (Triozidae)


Eggs may be laid under the leaf epidermis (left), and 1st instar nymphs become enclosed in the leaf as they feed (right)


Galls can be produced singly or become joined when multiple galls develop close together (left and below); typically there is only one nymph per gall chamber (right and below)

Molecular Phylogeny (12S)

Molecular phylogeny of Australian Triozidae based on the small subunit rRNA (12S). Yellow branches indicate the genus Schedotrioza on Eucalyptus. Grey branches indicate Trioza sp. from Allocasuarina verticellata, and blue branches indicate Trioza sp. from Casuarina cunninghamiana.

Two ** indicate bootstrap support values greater than 90% in both neighbour-joining and maximum parsimony analyses. One * indicates greater than 90% in neighbour-joining only. The nodes with hash marks (//) collapse in the strict consensus of the maximum parsimony analysis. An 'X' indicates four species (all from Casuarina cunninghamiana) which I experimented with but which did not seem to produce sound. Sound was recorded from all other species.



DNA extraction and sequencing of the 12S region was undertaken by Martyn Kennedy (University of Otago).

This research is funded by The Leverhulme Trust with an equipment grant from the Systematics Association. I have collaborated with Gary Taylor (University of Adelaide) on work with psyllids. Molecular data were generated by Martyn Kennedy (University of Otago).
