Rothamsted suction trap captures for week ending 4 May

This alert summarises up-to-date results from the Rothamsted/SASA suction-trap (ST) network and the FERA yellow water-pan trap (YWT) network: ahdb_aphid_news_20140509.pdf

Most aphids, as predicted, are flying two to four weeks earlier than usual. This is mainly as a result of the mild winter, helped by the favourable conditions of spring. The very wet winter does not appear to have had a major impact. Spring crops, especially if sown/planted later than usual are expected to be at higher than usual risk from aphids.

Peach–potato aphid is flying earlier and in larger numbers than usual. The potato aphid has been caught as far north as Elgin. Cabbage aphid is already on the wing in the far South and is expected generally to fly earlier than usual.

Willow–carrot aphid is flying throughout England a week or so earlier than usual.

Pea aphid is flying in the South East two to four weeks earlier than usual.
