A case of ‘‘pseudo science’’? A study claiming effects of the Cry1Ab protein on larvae of the two-spotted ladybird is reminiscent of the case of the green lacewing

A recent report on the potential negative impact in a laboratory setting of the Cry1Abprotein on larvae of the two spotted ladybird Adalia bipunctata (Schmidt et al. 2009) has gained notoriety. It was used in Germany, along with some other studies supposedly showing a negative impact of the transgenic MON810 maize on non-target organisms, to temporarily ban the cultivation of this Bt-maize under a safeguard clause conforming with Article 23 of the EU directive 2001/18/ EC.
This decision, although officially communicated as based on new evidence, was in fact based on flawed science and has been recognized to be politically motivated by a number of the stakeholders involved (Sinha 2009). The present temporary ban of MON810 by the German Government will now be considered by the EU commission, which will consult the European Food Safety Authority (EFSA), and then decide on the merits of the scientific data. Whether the ban will then be lifted or not lies within the commitological decision making process within the European Union.
Overall, the findings and interpretations in Schmidt et al. and the consideration of this paper for the justification of the ban of MON810 in Germany appear erroneous.
Children who are genetically predisposed to overweight, due to common gene variants, can still lose weight by changing their diet and exercise habits. Around 750 children and adolescents with overweight or obesity undergoing lifestyle intervention participated in the study conducted by researchers from the University of Copenhagen and Holbæk Hospital.
