The latest edition of AHDB Aphid News has just been published.
Peach–potato aphids (Myzus persicae) were caught at eight suction trap sites and increased in number at five. The highest numbers caught were from Kirton (29) and Preston (28).
- No mealy cabbage aphids (Brevicoryne brassicae) were caught this week.
- The willow-carrot aphid (Cavariella aegopodii) was caught in six traps this week. Eight male individuals were caught from York, suggesting that autumn migration back to willows is continuing.

- 7 carrot flies
In 3 water traps in a plot of swedes.
