Aphid bulletins

The latest editions of the Rothamsted Suction Trap Bulletin and AHDB Aphid News are attached. The information of interest to vegetable and salad growers is as follows:

• The peach–potato aphid has been caught at six sites in southern and eastern England this week, including a first arrival at Silwood within a few days of both the 10-year average and the forecast.

• The potato aphid has been caught at four sites this week in low numbers, and found on lettuce in Kent.

• Numbers of the willow ̶ carrot aphid (Cavariella aegopodii) have increased this week, with highest numbers in south eastern England.

• The first mealy cabbage aphid (Brevicoryne brassicae) caught in our UK traps this year turned up at Writtle this week, almost two weeks earlier than the 10-year average.

• Five pea aphids (Acyrthosiphon pisum) were caught this week across three sites in southern England.

• The black bean aphid (Aphis fabae) has been caught at six sites this week.

• This week’s suction trap catches were dominated by a big flight of sycamore aphids.
