      abstract     = {Upon attack by predators or parasitoids, aphids emit
                      volatile chemical alarm signals that warn other aphids of a
                      potential risk of predation. Release rate of the major
                      constituent of the alarm pheromone in pea aphids
                      (Acyrthosiphon pisum), (E)-b-farnesene (EBF), was measured
                      for all nymphal and the adult stage as aphids were attacked
                      individually by lacewing (Chrysoperla carnae) larvae.
                      Volatilization of EBF from aphids under attack was
                      quantified continuously for 60 min at 2-min intervals with a
                      rapid gas chromatography technique (zNose) to monitor
                      headspace emissions. After an initial burst, EBF
                      volatilization declined exponentially, and detectable
                      amounts were still present after 30 min in most cases. Total
                      emission of EBF averaged 16.33 +/- 1.54 ng and ranged from
                      1.18 to 48.85 ng. Emission was higher in nymphs as compared
                      to adults. No differences between pea aphid life stages were
                      detected for their speed of alarm signal emission in
                      response to lacewing larvae attack. This is the first time
                      that alarm pheromone emission from single aphids has been
                      reported.},
