SUMMARY The effect of dodecanoic acid, a behaviour‐controlling chemical which alters aphid feeding behaviour and virus transmission efficiency, was studied under field conditions. In a first experiment, dodecanoic acid reduced the level of natural colonisation of sugar beet by Aphis fabae. A second experiment revealed no significant influence of dodecanoic acid on the secondary spread of the semi‐persistent beet yellows virus and the persistent beet mild yellowing virus.
