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.},
