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

Peach–potato aphids (Myzus persicae) have been caught throughout much of England in both the suction traps and the yellow water 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 traps and the yellow water traps.
Currant-lettuce aphids (Nasonovia ribisnigri) were caught at Writtle and Wye this week.
The willow–carrot aphid is flying throughout England, with numbers increasing significantly at most suction-trap sites and with highest numbers at York (208), Kirton (184), Broom’s Barn (162) and Hereford (245).
Numbers of parsnip aphids also increased, particularly in central England
A few black bean aphids have been caught, but no field reports yet.
