As we described in our rebuttal in Transgenic Research (Shelton et al. 2009), we think that the meta-analysis approach used by Lo¨ vei et al. (2009) suffers from important methodological limitations relative to risk assessment that led them to reach conclusions that are in conßict with those of several recent comprehensive reviews and meta-analyses about the effects of Cry proteins on natural enemies. In particular, we believe that in their analyses they often attributed hazard to a protein rather than, more accurately, to poor prey or host quality. The rebuttal by Andow et al. (2009) does not correct this mistaken comparison or address our other major concerns. In this response to their letter we clarify misrepresentations of our original statements, refocus the discussion on methodology, and re-emphasize the additional main points of our initial rebuttal that Andow et al. (2009) did not address in their response.
