Engineering genes encoding insecticidal proteins into crop plants offers nu
merous benefits to agriculture. However, like many conventional insecticide
s, this new technology has the potential to disrupt natural biological cont
rol through both direct and indirect side effects of the plants on the fitn
ess or behaviour of arthropod predators and parasitoids. Interactions betwe
en transgenic plants and these beneficial insects are being assessed to avo
id incompatibility.
