Abstract
In Europe Btcorn resistant against the European Corn Borer has until now been the only genetically modified plant to be grown commercially With the advent of the Western Corn Rootworm Btcorn varieties with resistance against Coleoptera will become important The cultivation of Btplants may have negative impacts on nontarget organisms ie all species not explicitly targeted by a given Btcrop One prominent nontarget group in corn are the herbivorous plant bugs Heteroptera Miridae They are common abundant and exposed to the Cryprotein We therefore assessed the potential impact of the cultivation of the Cry3Bb1expressing Btcorn variety MON88017 and three conventional varieties on this group Trigonotylus caelestialium Kirkaldy was the most abundant plant bug at the experimental field There was no evidence for a negative impact of MON88017 on this species despite its considerable exposure to Cry3Bb1 demonstrated with ELISA The conventional corn varieties however had a consistent and significant influence on the field densities of this species over all three growing seasons
