They have had their genes changed to contain a special characteristic, like resistance to certain insects.

For example, Zeneca has managed to switch the bt gene, which gives maize plants resistance to nasty insects, on and off using another chemical trigger.

ECONOMIST: Terminator genes

The producers argue that the engineered traits such as resistance to certain brands of herbicide or types of insects and virus actually do ecological good by reducing chemical use and improving yields so that less land needs to go under the plough.

ECONOMIST: Who��s afraid?

The scientists also believe that unlike with insecticides, where as many as 80% of mosquitoes are no longer killed by the compounds, the insects are unlikely to develop resistance to the fungus as it targets many different genes in the parasite.
