The expression of the insecticidal toxin Cry3Bb1 in maize MON 88017 can curb spreading of the Western corn rootworm (WCR, Diabrotica virgifera virgifera), and the tolerance of this maize to glyphosate can facilitate weed management. To examine the general environmental impact of this GM maize, it was planted along with a non-GM but otherwise nearly isogenic cultivar (treated or not treated with the insecticide Dursban 10G) and with two reference cultivars. Effects on non-target organisms were studied in each treatment on 5 plots of 0.5 ha each. The content of Cry3Bb1 measured in plant tissues by ELISA fluctuated during season and depended on the weather condition and the growth phase of maize. The diversity and abundance of plantdwelling arthropods (plant sucking arthropods, predators, and parasitoids) and epigeic arthropods (spiders, ground and rove beetles) were monitored three times and five times during the season, respectively. Neither the abundance nor the species composition, were affected by the transgenic plant. The data indicate that MON 88017 has no effect on the non-target arthropod fauna.
