In order to obtain stable and simple structural aphid alarm pheromone mimics, (E)-2, 6, 10-trimethylundeca-1, 5, 9-triene and several related analogs, so-called nor-farnesenes, were synthesized and tested for alarm pheromone activity against the aphids Schizaphis graminum(RONDANI) and Acyrthosiphon pisum(HARRIS)(Homoptera : Aphididae). Three compounds showed significant alarm pheromone activity and may have potential in aphid pest management.
