Diana has worked within the Insecticide Resistance Group for over twenty years utilising biochemical and molecular screening methods to study insecticide resistance mechanisms and frequencies. Her key research area is monitoring the insecticide resistance profile of aphid species in both field populations and suction trap populations in Europe and the UK. Diana’s knowledge and experience includes the monitoring of pyrethroid, carbamate and neonicotinoid resistance in the peach potato aphid Myzus persicae. Her latest project also includes monitoring of these resistance mechanisms alongside the frequency of virus yellows in Myzus persicae populations caught in the Rothamsted Insect Survey suction traps (a nationwide network that collects data on the migration of aphids). This kind of continued monitoring is vital to optimise insecticide usage and preserve modes of action ensuring a future sustainable use of insecticides in crop protection management.
