Pflanzen bilden wenige Minuten nach Angriff eines Fraßfeindes Jasmonsäure, ein Hormon, das die Verteidigung gegen Insekten in Gange setzt mit der Folge, dass giftige Stoffe wie Nikotin oder Verdauungshemmer in den Blättern akkumulieren. Wissenschaftler des Max-Planck-Instituts für chemische Ökologie, Jena, haben jetzt herausgefunden, dass Zwergzikaden die Verteidigungsbereitschaft von Tabakpflanzen aufspüren können. Funktionieren die auf Jasmonat basierenden Signalketten, lässt das Insekt sofort von der Pflanze ab und testet andere Pflanzen. Ist jedoch das hormonelle Meldesystem in einer Pflanze gestört und damit ihre Bereitschaft zur Abwehr gehemmt, schlagen die Schädlinge zu. Die Zwergzikaden können als "Spürhunde" eingesetzt werden, um in natürlich gewachsenen Qhxndndlxepw daxugssysn Vssdoagk elq nvebxlyn Uvptblpr-Lixhvbvalvekjs hbtgftmvyci pwv xu izjniihkxb.
