Impact of Genetically Modified Crops on Pollinators
Abstract
Evaluating the potential for genetically modified (GM) crops to have a negative impact on pollinating insects has long been recognized as an important part of risk assessment of such plants. Extensive field experience with commercial GM crops, bred for herbicide tolerance or insect resistance using Bacillus thuringiensis ( Bt ) crystal (Cry) toxin genes, has shown no deleterious effects on pollinators. Many other insecticidal GM plants, not yet commercialized, have been studied to see if they could be hazardous to bees. Of these, only some of the protease inhibitors and lectins could present dose-dependent hazards to bees if there were realistic routes for sufficiently high exposure. A good understanding of crop pollination biology is essential for adequately assessing risks of GM plants to pollinators. In addition, information on crop pollination will aid the study of transgene flow since pollinators could play a role in the transfer of transgenes from GM plants to non-GM crops or wild relatives.

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.
