α-Farnesene: Isolation from the natural coating of apples
TLDR
In this article, the isolation of a pure sesquiterpene hydrocarbon from the natural coating of Granny Smith apples was described, based on its ultraviolet, infrared, mass, and N.M.R. spectra, which established it as an α-farnesene stereoisomer with a trans configuration assigned to the 9,10 double bond and a likely trans configuration of the 6,7 bond.Abstract:
The isolation of a pure sesquiterpene hydrocarbon from the natural coating of Granny Smith apples is described. Evidence mainly from its ultraviolet, infrared, mass, and N.M.R. spectra establish it as an α- farnesene stereoisomer (I) with a trans configuration assigned to the 9,10 double bond and a likely trans configuration of the 6,7 bond. Its infrared, mass, and N.M.R. spectra and those of trans-β-farnesene (II) are reported.read more

Composition of aphid alarm pheromones
TL;DR: Analysis of single cornicle droplets from six species of aphid showed the presence of volatile components in addition to (E)-β-farnesene, the major component of the alarm pheromone of Phorodon humuli was (E), even though farnesenes are present in the summer hostHumulus lupulus.

Experimental analysis of insect behaviour
TL;DR: In this paper, an analysis of direction finding in male Mosquitoes and the development of the flight pattern in Locusts is presented, as well as the role of the Hydrocarbon?-Farnesene in the behaviour of Codling Moth Larvae and Adults.

Trans-β-farnesene, Alarm Pheromone of the Green Peach Aphid, Myzus persicae (Sulzer)
TL;DR: The chemical structure of the repellent odour found in the cornicle secretion of the aphid M. persicae1 has been identified as trans-β-farnesene.

Pattern of volatile compounds in dominant and subordinate male mouse urine.
TL;DR: The urinary volatiles from dominant and subordinate male mice were chromatographically compared, both immediately and seven days after dominant-subordinate relationships between pairs were formed, revealing that 16 urinary compounds exhibited substantial concentration differences depending upon social status of the animals.

Antennal perception of oilseed rape,Brassica napus (Brassicaceae), volatiles by the cabbage seed weevilCeutorhynchus assimilis (Coleoptera, Curculionidae).
TL;DR: The response of theCeutorhynchus assimilis antenna to volatiles in air entrainment-derived extracts of oilseed rape, Brassica napus, was studied using coupled gas chromatography-electroantennography (EAG) and coupled GC-single cell recording (SCR).
