trans-beta-Farnesene

trans-beta-Farnesene is a volatile sesquiterpene hydrocarbon that has been found in aphids and has alarm pheromone and kairomonal attractant activities. It is produced by aphids in response to predator or parasite attack. trans-beta-Farnesene (0.2 ng) induces dispersion of 50% of M. persicae aphids from a cluster. trans-beta-Farnesene (>2 µg) also acts as a kairomone, attracting larvae and adults of A. bipunctata, a predator of aphids.Formal Name: (6E)-7,11-dimethyl-3-methylene-1,6,10-dodecatriene.
