| Description | (E)-β-Farnesene (trans-β-Farnesene) is a sesquiterpene hydrocarbon present in Phlomis aurea Decne and is the main component of many aphid alarm pheromones that interrupt aphid feeding. (E)-β-Farnesene impairs development and survival of Chilo suppressalis larvae by disrupting insect hormone balance. |
