Sex smell lures 'vampire' to doom

A synthetic "chemical sex smell" could help rid North America's Great Lakes of a devastating pest, scientists say.
US researchers deployed a laboratory version of a male sea lamprey pheromone to trick ovulating females into swimming upstream into traps.
The sea lamprey, sometimes dubbed the "vampire fish", has parasitised native species of the Great Lakes since its accidental introduction in the 1800s.
The work is reported in Proceedings of the National Academy of Sciences.
