- 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.
