Aphid captures by Rothamsted traps

Trap captures of pest aphids relevant to vegetable and salad crops to date are in the attached file. On the whole aphid activity is continually decreasing as most insects will be in, or entering, their overwintering stages. However, brassica growers should still monitor crops for aphids and also cabbage whitefly. Whilst relatively large numbers of willow-carrot aphid are being captured in suction traps, these are not an immediate threat to crops as they are returning to willow to overwinter.
