                                Technical Abstract: Social insects utilize complex pheromone systems to maintain sociality and, in the case of most ant species, colony integrity. Colony integrity is expressed as nestmate recognition, where colony members can discriminate between nestmates and conspecific non-nestmates by matching an experience based neural template of their colony odor with the cues detected on the cuticle of an intruder.  If the cues and template do not match, e.g. a non-nestmate intruder, then aggression occurs.  There is a large body of correlative data linking nestmate recognition and cuticular hydrocarbons, but little evidence of direct cuticular hydrocarbon involvement.  Multivariate analyses of hydrocarbon patterns can differentiate one colony from another; however, it is not clear if the ants can also differentiate colonies based on cuticular hydrocarbons. We present here a review of the use of fire ant cuticular hydrocarbons as models for heritable nestmate recognition cues and as tools for monitoring movement of cuticular hydrocarbons in a colony. We then describe a new method for putting physiologically relevant amounts of treatment hydrocarbons on the cuticle of workers, which we used to evaluate the role of hydrocarbons in fire ant nestmate recognition.
