Potato aphid 2010

The Potato aphid (Macrosiphum euphorbiae) is often the most numerous of the five or six species of aphids that colonize potato crops in Scotland. It is also an important aphid vector of non-persistent potato viruses (e.g. PVY).
Potato aphids have had a very slow start to 2010. Only 22 Potato aphids have been recorded in Scottish suction traps up to the 1 August, the fewest recorded to this date in the last 27 years. In the Scottish aphid traps, the first Potato aphid (Macrosiphum euphorbiae) of 2010 was caught on 19 May at Ayr.
