The aphid fauna of south-western Australia was surveyed during each potato growing season (October to May) 1988-1992. Thirty-three species of aphids were detected in the survey.

Of these, green peach apid was the most widespread. Green peachpid poses the greatest threat to the potato growing industry because of its superior ability to transmit plant viruses that cause disease in potatoes, most notably potato leaf roll virus (PLRV). Fewer green peach apids were recorded at southern sites th
