SUMMARY A derivative, prepared from the aphid alarm pheromone (E)‐β‐farnesene and the saturated straight 14‐carbon chain dialkyl ester of acetylene dicarboxylic acid, was the most active compound tested for inhibiting acquisition by the aphid Myzus persicae of the non‐persistently transmitted potato virus Y (PVY). Derivatives lacking, or with shorter, or branched or partially‐unsaturated carbon side‐chains were less active. The one derivative tested also inhibited inoculation of PVY, and acquisition of beet mosaic virus (also non‐persistent) and the semi‐persistent beet yellows virus. However, it had no obvious effect on aphid probing behaviour; related compounds lacking the (E)‐β‐farnesene moiety also inhibited acquisition of PVY.
