AHDB Aphid News

The latest edition of AHDB Aphid News has just been published. Highlights relevant to vegetable and salad crops below:

• A cool, dry and windy week has restricted aphid flight across much of the country, with the notable exception of Starcross in the South West. The forecast of frosts over the next week will likely limit aphid population growth on the ground. 
• Four peach–potato aphids were caught this bulletin week in western England (Hereford 1 and Starcross 3).
• No further willow ̶carrot aphids were caught this bulletin week. 
• A single pea aphid was caught this week at Wye, it was a first arrival for this site and about three weeks earlier than the 10-year mean. 
• No potato aphids, mealy cabbage aphids or black bean aphids have been caught so far this year. 
• The shallot aphid (Myzus ascalonicus) remains the most numerous aphid species in our suction-trap samples to date
