Host plants and obligate endosymbionts are not the sources for biosynthesis of the aphid alarm pheromone

Abstract (E)-β-farnesene (EβF) is the major component of the alarm pheromone of many aphid species, but where EβF is synthesized in aphids is only partly understood. There are at least three most possible sources for the alarm pheromone: host plants, aphid obligate endosymbiont and aphids themselves...
