Science-Based Risk Assessment for Nontarget Effects of Transgenic Crops

TRANSGENIC PLANTS AND INSECTS Field Studies Assessing Arthropod Nontarget Effects in Bt Transgenic Crops: Introduction

Advancing environmental risk assessment for transgenic biofeedstock crops

Transgenic modification of plants is a key enabling technology for developing sustainable biofeedstocks for biofuels production. Regulatory decisions and the wider acceptance and development of transgenic biofeedstock crops are considered from the context of science-based risk assessment. The risk assessment paradigm for transgenic biofeedstock crops is fundamentally no different from that of c...

Nontarget effects of transgenic insecticidal crops: implications of source-sink population dynamics.

Widespread planting of transgenic insecticidal (TI) crops for pest control has raised concerns about potential harm to nontarget arthropods. Because the first generation of TI crops produce single Bacillus thuringiensis (Bt) toxins causing little or no harm to most nontarget arthropods, they are not likely to cause such negative effects. However, varieties of transgenic crops with multiple Bt t...

Transgenic Crops: An Environmental Assessment

TRANSGENIC PLANTS AND INSECTS Utility of Ground Beetle Species in Field Tests of Potential Nontarget Effects of Bt Crops

Characteristics of groundbeetles (Coleoptera:Carabidae), including their distribution, diet breadth, and importance as generalist predators, make them candidates for evaluating potential unintended effects of transgenic crops. The abundance and composition of carabids collected from pitfall traps placed in hybrid dent cornwere used to determinewhich species are consistently present and abundant...
