"A major field trial of GM wheat that is designed to repel aphids has found the crop is no better protected against the pests than conventional wheat.

The results come from two years of trials that compared aphid attacks on standard wheat plants with those suffered by a GM version modified to release a natural aphid repellant.

The publicly-funded trial ran under heavy security at Rothamsted Research in Hertfordshire in 2012 and 2013 after it was targeted by anti-GM campaigners who threatened a day of direct action to trash the crops."
