Peach-Potato Aphid

The Peach-Potato aphid Myzus persicae has traditionally been considered as the most important aphid vector of potato viruses. However, in Scotland, Peach-Potato aphids generally fly later and in far lower numbers than in warmer countries and their relative scarcity generally makes this species less of a concern to potato growers.  In some years, usually following a particularly mild winter, Peach-Potato aphids can present a very high risk of virus transmission, particularly Leaf Roll, within the Scottish seed potato crop.
