Transgenic crops expressing Bacillus thuringiensis toxins and biological control
Abstract
The area devoted to growing transgenic plants expressing insecticidal Cry proteins derived from Bacillus thuringiensis (Bt) is increasing worldwide. A major concern with the adoption of Bt crops is their potential impact on nontarget organisms including biological control organisms. Regulatory frameworks should advocate a step-wise (tiered) approach to assess possible nontarget effects of Bt crops. Laboratory and glasshouse studies have revealed effects on natural enemies only when Bt-susceptible, sublethally damaged herbivores were used as prey or host, with no indication of direct toxic effects. Field studies have confirmed that the abundance and activity of parasitoids and predators are similar in Bt and non-Bt crops. In contrast, applications of conventional insecticides have usually resulted in negative impacts on biological control organisms. Because Bt-transgenic varieties can lead to substantial reductions in insecticide use in some crops, they can contribute to integrated pest management systems with a strong biological control component.

“Reduced numbers of target pests, reduced nutritional quality of the remaining ones, and lack of host-derived or induced attractant cues may particularly affect parasitoids specialized to target pests, such as M. cingulum or Tachinidae [34, 47].”

In the citing paper
“numerous non-target laboratory studies with a wide range of taxa using purified Bt proteins, plant material, or prey that had consumed Bt proteins have demonstrated the specificity of Cry1- and Cry2-class proteins to Lepidoptera and Cry3-class proteins to Chrysomelidae (Coleoptera) [47, 61–63].”

In the citing paper
“This can lead to adverse effects on the natural enemy that are related to the reduced quality of the prey/host rather than to the insecticidal protein itself (Fig. 3) (Naranjo, 2009;Romeis et al., 2006).”

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.
