Aphid monitoring in the UK

Aphids are pests on a wide range of agricultural, horticultural and forest crops, as a result of which there is a need to monitor their distribution and abundance in order to guide decisions on control. Several complementary systems are in place to achieve this, each differing in its scope. Information coming from these systems may sometimes appear contradictory, but there will always be an explanation for this.

The operators of three systems have decided to produce regular overviews, outlining the headline stories apparent from expert consideration of the available evidence. The overviews will provide a link to each system where more detail can found if required.

Further information and the first overview can be found here: ahdb_combined_aphid_summary_20130524.pdf

The latest Aphid Bulletin has just been released. Aphid activity is still very low.

However, 4 willow-carrot aphids (below) were caught at Broom's Barn and one at Writtle.

One potato aphid was caught at Rothamsted and we have also found a few potato aphids on one of our brassica plots at Wellesbourne.
