New edition of AHDB News published

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

• Peach・potato aphids (Myzus persicae) have been caught throughout much of England in the suction-traps and in the Midlands, East Anglia and the South West in the yellow water-pan traps. Tests show these migrants are carrying high levels of Turnip yellows virus.
• Low numbers of the mealy cabbage aphid were caught less widely in both suction and yellow water traps.
• Single currant-lettuce aphids (Nasonovia ribisnigri) were caught at Hereford and Rothamsted this week.
• The willow ̶carrot aphid was caught at twelve sites this week, with numbers increasing at 11 sites and highest numbers at Kirton (60) and Hereford (53).
• Numbers of parsnip aphids, particularly Cavariella theobaldi, also increased.
