Plant induced responses mediate interactions between herbivores from different feeding guilds

Presented at the All Scientists Meeting (2015-04-15 to 2015-04-16 )

Plants use a variety of cues to detect attacking herbivores. Furthermore, signal transduction pathways notify the plant of the specific type of attacker and thus induce a specialized defense. Here we test how an induced response from an early colonizing phloem-feeder influences the performance and host-plant preference of a late-arriving foliage-feeder in order to reveal the underlying mechanisms of plant-insect interactions when herbivores co-occur in the field.
