Rothamsted suction trap samples for the week ending 11 May

The 6th issue of AHDB Aphid News has just been released.

Aphid flight activity decreased temporarily this week because of a period of adverse weather, but is sure to be picking up soon. This is still looking like an early, large start to the aphid season.

• The peach–potato aphid (Myzus persicae) was caught at five sites. Field reports of this species on untreated sugar beet and on baby leaf brassicas were received from eastern England.

• Two potato aphids (Macrosiphum euphorbiae) were caught, including a first arrival at Preston.

• Two pea aphids (Acyrthosiphon pisum) were caught at Elgin but none elsewhere this week.

• No cabbage aphids (Brevicoryne brassicae) were found in the UK traps this week, but a field report from eastern England of large numbers on game cover kale was received.

• The willow carrot aphid (Cavariella aegopodii) was caught at six sites in low numbers.
• One currant lettuce aphid (Nasonovia ribisnigri) was caught at Writtle - the first of the year.
