European Commercial Genetically Modified Plantings and Field Trials
Abstract
Genetically modified (GM) maize crops expressing the Cry1Ab toxin from Bacillus thuringiensis ( Bt maize) have been cultivated in Spain on a commercial scale since 1998, reaching an area of about 75,000 ha (around 21% of total maize-growing area) in 2007. A post-market environmental monitoring plan for the Bt maize varieties derived from Event Bt 176 was carried out during the period 1998-2005, and a second ongoing monitoring plan for Bt maize varieties derived from Event MON810 was initiated in 2003. Both of these consider case-specific monitoring for the evolution of resistance in target insects, as well as for the potential effects on non-target arthropods. Monitoring for field resistance in target insects, Sesamia nonagrioides and Ostrinia nubilalis , is being assessed by changes in susceptibility from baseline levels. To date, no changes in their susceptibility to the Cry1Ab toxin have been found, which is consistent with the fact that there have been no control failures reported in transgenic Bt maize fields. Field trials to determine potential effects of Bt maize on non-target arthropods have focused on three functional groups: herbivores, predators and parasitoids. No detrimental effects have been observed on any of the main predatory groups that are common in maize fields. Nevertheless, field trials in the same areas for longer periods are necessary to discard long-term potential cumulative effects.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
