This web page hosts the latest guidance from the Insecticide Resistance Action Group (IRAG). The 'Download' button provides background. Scroll down for guidance.
The AHDB-supported Resistance Action Groups (RAGs) are informal, UK-based groups consisting of experts from the Crop Protection Association (CPA) member companies, other representatives from the agrochemical industry, a range of independent organisations, including public-sector research institutes, and the Chemicals Regulation Directorate (CRD).
The groups are completely independent of AHDB and work to produce guidance on pesticide resistance issues. As part of its support to the resistance action groups, AHDB publishes their guidance.

Aphid sampling protocol
Help us safeguard the efficacy of insecticides
As part of a UK aphid-monitoring programme, Rothamsted Research needs aphid samples, especially those that unexpectedly survive treatment with insecticides. Although any aphid species can be submitted, the researchers focus on some species/situations more than others to reflect samples received and the need to detect new resistance issues emerging in the UK aphid population.
