000062748 520__ $$aGenetic 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.
