Considerations on the use of transgenic crops for insect control
The adoption of agricultural technologies, whether developed through biotechnology or other methods, depends on social, political, regulatory and biological parameters. This article first presents an example of a low-input, non-biotechnological method of pest control that, while seemingly reasonable to researchers and extension agents, was not adopted by farmers. It then analyses a method for insect management developed through biotechnology that is becoming widely adopted: transgenic plants expressing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt). Globally increasing adoption of Bt plants, by small and large farmers in both low- and high- income countries requires explanation in terms of biological properties of cropping systems and insect populations, alternative control techniques and social policy considerations.
