Stapelweise Petrischalen, darin Stücke von Maisblättern. Erst beim näheren Hinsehen entdeckt man die winzigen Tierchen, die das Innere der Plastikdosen bevölkern: Weichwanzen, in allen Altersstufen. Eva Schultheis von der RWTH Aachen versorgt die Tiere mit frischem Blattmaterial. Während ihres gesamten Lebenszyklus haben die Wanzen ausschließlich Blätter einer von vier verschiedenen Maissorten im Angebot, darunter gentechnisch veränderter Bt-Mais. Der Fraßversuch soll zeigen, ob Bt-Mais die Wanzen schädigt.
Eva Schultheis hat für den Fraßversuch lebende Weichwanzen der Art Trigonotylus caelestialium auf dem Maisversuchsfeld eingefangen und nach Aachen gebracht.
