Peach-Potato aphid 2009

The Peach-Potato aphid (Myzus persicae) is the most important aphid vector of potato viruses. In Scotland, differences in flight phenology mean that M. persicae generally flies later and in far fewer numbers than in England.
The first Peach-Potato aphid Myzus persicae was recorded from the Dundee suction trap on 30 May. This aphid was 17 days earlier than the predicted date for the first Peach-Potato aphid at this site.
As of 4 October, the total number of 120 Peach-Potato aphids caught in the four Scottish traps in 2009 ranks fourteenth highest over the last 26 years. Of these aphids 72% have been caught at Elgin, 14% at Dundee and 14% at Edinburgh.
