Sentence: Returning successful patrollers have an even greater effect on foraging activity: foragers will not leave the nest unless a patroller returns (Gordon, 2002), and the rate of foraging in a colony can be controlled by rolling glass beads coated with cuticular hydrocarbons extracted from patrollers into the nest (Gordon & Greene, 2003; Greene & Gordon, 2007).
Intensity score:
