AHDB Aphid News
The latest edition of AHDB Aphid News has just been released.
-
Peach–potato aphids (Myzus persicae) were caught and increasing in number at nine suction trap sites. The highest number caught was from the suction trap at Wellesbourne (23).
- Mealy cabbage aphids (Brevicoryne brassicae) were caught at Kirton (5) and Writtle (1) suction trap sites.
- Monitoring brassica crops for aphids would be useful.
- The willow-carrot aphid (Cavariella aegopodii) was caught in five suction-traps this week. numbers have increased most noticeably at Dundee and to a lesser extent at York suction trap sites. A single male individual was caught from Dundee suggesting that the start of the autumn migration back to willows to overwinter may be occurring.
