'No entry' signal in ant foraging
Article Abstract:
Forager ants lay attractive trail pheromones to guide nestmates to food but evidence for a negative trail pheromone, deployed by Pharaoh's ants as a 'no entry' signal to mark an unrewarding foraging path is illustrated. Evidence shows that Pharaoh's ants use a sophisticated trail system with a negative, repellent pheromone to mark unrewarding branches.

Trail geometry gives polarity to ant foraging networks
Article Abstract:
An attempt is made to show that by using information from the geometry of trail bifurcation within the network, foragers joining a trail cases reorient ate them if they work in the wrong direction. The frequency of correct reorientation is maximized when the trail bifurcation angle is approximately 60 degrees as found in natural networks.
