Abstract: Stop them in their tracks Foraging ants have evolved sophisticated means of communication using attractive trail pheromones to guide their nestmates to food or water. These systems are widely studied and have even provided algorithms relevant to human traffic, computer and communication networks. Now it seems there may be a ‘stop’ sign to augment the familiar ‘go’ in Pharaoh's ants. They use a repellent pheromone to mark unrewarding paths, concentrating the signal at decision points such as trail bifurcations.
