AHDB Aphid News

The latest edition of AHDB Aphid News has just been published.

  • Peach–potato aphids (Myzus persicae) were caught at twelve suction trap sites. The highest number caught was from the trap at Hereford (42).
  • Mealy cabbage aphids (Brevicoryne brassicae) were caught and increasing in number at Kirton (6), Hereford (1) and Wye (4).
  • The willow-carrot aphid (Cavariella aegopodii) was caught in four sites this week. Numbers have increased most noticeably at Dundee and to a lesser extent at York and Kirton . A further four male individuals were caught from Dundee this week suggesting that the autumn migration back to willows to overwinter is underway
