Update on suction trap captures for week ending 13 April.

The most recent edition of AHDB Aphid News has just been published: ahdb_aphid_news_20140417.pdf

More aphids have been captured 'early':

• Four peach–potato aphids were caught (Broom’s Barn 3 and Kirton 1). The first arrival at Broom’s Barn was over four weeks earlier than the 10-year mean.
• A field report from eastern England identified a peach–potato aphid on a sugar beet crop at the cotyledon stage. Further field observations indicate aphids are flying, especially potato aphids.
• Three potato aphids (Macrosiphum euphorbiae) were caught, including first arrivals at Rothamsted and Kirton, four to five weeks earlier than the ten year means.
• The shallot aphid (Myzus ascalonicus) is the most numerous aphid species to date, with particular hotspots at Kirton and Wye.
• No cabbage aphids (Brevicoryne brassicae), willow carrot aphids (Cavariella aegopodii) or pea aphids (Acyrthosiphon pisum) were caught his week.
