Abstract

The objective of this study was to observe the response of the bird cherry oat aphid, Rhopalosiphum padi (Linnaeus, 1758) to field rate equivalents of insecticides, by using bioassays of vials coated with the pyrethroid, λ-cyhalothrin. The results from the geographically separated Irish R. padi colonies indicated a susceptible response, which was a similar finding to the UK which showed sensitivity in this species of cereal aphids. Monitoring the susceptibility status of aphids using bioassays gives information regarding developments of any tolerance, which could be a precursor, or resistance against the target chemical insecticide, which is an important integrated pest management tool.
