The purpose of this paper is to summarize scientific and regulatory information on nontarget invertebrate testing and evaluation of new products expressing insecticidal proteins in an ecological risk assessment. The information included provides a general discussion for conducting non-target invertebrate ecological risk assessments for crops expressing insecticidal proteins. This paper is not intended as official policy or guidance; it is unknown at this time if it will lead to future guidance.
