Insect resistance management in GM crops: Past, present and future

Article Abstract:

Transgenic plants expressing insecticidal proteins from the bacterium Baccilus thuringiensis (Bt) were commercialized in 1996 amid concern from some experts that the widespread use of Bt crops would inevitably lead to resistance and the loss of 'public good'. Researchers and regulators are again looking for opportunities to reassess the risk of resistance and the most effective strategies to preserve Bt and other novel inset-resistant crops in development.

Transgenic plants expressing two Bacillus thuringiensis toxins delay insect resistance evolution

Article Abstract:

A unique model system consisting of Bt transgenic broccoli plants and the diamondback moth, Plutella xylostella is developed. It is reported that plants containing two dissimilar Bt toxin genes can delay resistance more effectively than single-toxin plants used sequentially.

Assessment of risk of insect-resistance transgenic crops to nontarget arthropods

Article Abstract:

The basic principle and rationale of the scientifically rigorous tiered approach to assess the possible risks to nontarget arthropods (NTAs) posed by insect-resistant, genetically modified (IRGM) crops, within regulatory toxicology and environmental sciences is analyzed.
