Abstract A series of 3-acyl-4-hydroxycoumarins, structurally related to dicoumarol, as well as several alfalfa constituents including coumestrol were tested for their feeding deterrency towards the pea aphid. Feeding deterrency of the 3-acyl-4-hydroxycoumarins decreased as the size of the 3-acyl group increased.
