Potential side effects of insect-resistant transgenic plants on arthropod natural enemies.

Engineering genes encoding insecticidal proteins into crop plants offers numerous benefits to agriculture. However, like many conventional insecticides, this new technology has the potential to disrupt natural biological control through both direct and indirect side effects of the plants on the fitness or behaviour of arthropod predators and parasitoids. Interactions between transgenic plants and these beneficial insects are being assessed to avoid incompatibility.
