Thrips and Tospoviruses: This Symposium, officially titled Thrips, Plants, Tospoviruses: the
Millennial Review, was held in The meetings themselves proved very successful, despite some tospovirus workers indicating that they had no interest in thrips, and some thrips workers indicating that they had no interest in viruses. This was not unexpected. But the fact remains that tospoviruses are dependent on thrips for their survival in the field, and thrips are much more important as crop pests when they are vectoring tospoviruses. Moreover, the many biological phenomena involved in the interactions between plants, topoviruses and thrips remain remarkably little understood, in particular the origin (or origins) of their relationships. Indeed, one of the strongest signals coming from the meetings concerned our lack of evolutionary understanding, and thus our inability to predict the past or future trajectory of these relationships. The 59 submitted papers were issued on a cd-rom as a single electronic .pdf file that is fully searchable by computer but can be printed out in colour as a 390-page volume by anyone who would like a hard copy in their library. Copies of this cd-rom are available without charge from: laurence.mound@csiro.au

and efficiency of tospoviruses. The route of TSWV inside
the thrips body in relation to transmission efficiency. Impeded transmission
of defective isolates of Tomato spotted wilt virus by Frankliniella
occidentalis. Intraspecific variation
in transmission of TSWV by Frankliniella occidentalis result from
distinct virus accumulation. Accumulation and transmission
