Abstract

Windborne insect vectors constitute a potential pathway for crop virus introduction to Australia. Evidence was available for
genetic connectivity between partial sequences of Zucchini yellow mosaic virus (ZYMV) isolates from Kununurra and South East
Asia. In th is study,complete genomic sequences of ZYMV, Papaya ringspot virus (PRSV), Sweet potato feathery mottle virus
(SPFMV) and Sweet potato virus C (SPVC) were obtained. Close genetic connectivity occurred between ZYMV isolates from
Kununurra and East Timer, SPFMV isolates from East Timer, Kununurra and Cairns, and PRSV isolates from PNG, Broome,
Darwin and Ayr. This emphasises the importance of Australian biosecurity measures against this pathway.
