      abstract     = {Genetic variation in anti-predator traits has been shown
                      for a variety of species. Aphid alarm pheromone,
                      (E)-β-farnesene, is released by attacked aphids and causes
                      a variety of behavioral defense reactions in the signal
                      receivers. In pea aphids, Acyrthosiphon pisum Harris
                      (Homoptera: Aphididae), (E)-β-farnesene mediates the
                      production of winged offspring in the presence of natural
                      enemies. While variation in the propensity for pea aphids to
                      produce winged offspring is well-documented, little
                      quantitative information is available about clonal
                      differences in (E)-β-farnesene emission or the amount of
                      alarm pheromone released in aphid colonies. We tested the
                      wing induction response of four clones when attacked by a
                      predatory lacewing larva, Chrysoperla carnea (Stephens)
                      (Neuroptera: Chrysopidae), and found that three of the four
                      clones increased the proportion of winged offspring under
                      predator attack. We then investigated the emission of aphid
                      alarm pheromone of these clones of pea aphid under attack.
                      Alarm pheromone emission in aphid colonies of initially 25
                      adults varied from 81.2 to 10 851.0 ng per aphid colony over
                      24 h. There were no differences between clones in total
                      emission or in emission per consumption event. These results
                      show that there is substantial variability in alarm
                      pheromone emission within clones and that the propensity to
                      produce winged offspring in some clones is not a simple
                      function of the propensity of alarm pheromone production in
                      these clones.},
