| 产品描述 | trans-β-Farnesene is a volatile sesquiterpene hydrocarbon that has been found in aphids and has alarm pheromone and kairomonal attractant activities.[1],[2] It is produced by aphids in response to predator or parasite attack.[1] trans-β-Farnesene (0.2 ng) induces dispersion of 50% of M. persicae aphids from a cluster. trans-β-Farnesene (>2 μg) also acts as a kairomone, attracting larvae and adults of A. bipunctata, a predator of aphids.[2] Reference:
