Nestmate recognition is a critical element in social insect organization, providing a means to maintain territoriality and close the colony to parasites and predators. Ants detect the colony chemical label via their antennae and respond to the label mismatch of an intruder with aggressive behavior. In the fire ant, Solenopsis invicta, worker ability to recognize conspecific nonnestmates decreases if the colony queen is removed, such that they do not recognize conspecific nonnestmates as… 

Octopaminergic system in the brain controls aggressive motivation in the ant, Formica japonica.

It is suggested that OAergic system in the brain must involve in controlling aggressive motivation in the ants.

Behavioral Discrimination between Monogyne and Polygyne Red Fire Ants (Hymenoptera: Formicidae) in their Native Range

Assessment of discrimination behaviors of both polygynous and monogynous forms of the red fire ant, Solenopsis invicta Buren, during symmetrical interactions in neutral arenas identified monogyne and polygyne forms of S.invicta colonies in concordance with current measures, including number of queens and expression of the Gp-9 gene.

Neuromodulation of Nestmate Recognition Decisions by Pavement Ants

The results provide evidence that changes in octopamine and serotonin in the brains of individuals are sufficient to alter the decision by pavement ants to be aggressive towards non-nestmate ants whereas increased brain levels of dopamine correlate to physical fighting.

Nestmate recognition in ants ( Hymenoptera : Formicidae ) : a review

Models of decision rules and the role of CHCs in nestmate recognition are reviewed, including adjustable thresholds that account for graded responses and intra-colony individual variation in behavioral responses towards non-nestmates are explored.

Biogenic amine modulation of honey bee sociability and nestmate affiliation

It is suggested that dopamine is an important neurochemical component of social motivation in bees, and this finding advances a comparative understanding of the processes of social evolution.

Social interactions influence dopamine and octopamine homeostasis in the brain of the ant Formica japonica

It is suggested that social interactions with nestmates influenced brain biogenic amine homeostasis in stressed F. japonica and trophallaxis and grooming events recovered the brain OA levels.

Multiple functions of fire ant Solenopsis invicta mandibular gland products

The results of the present study indicate that male and female sexuals use mandibular gland secretions for mating flight initiation and during mating flights, suggesting new roles for mandIBular gland products in fire ants.

Polymorphism and division of labour in a socially complex ant: neuromodulation of aggression in the Australian weaver ant, Oecophylla smaragdina

It is demonstrated that octopamine (OA) modulates worker size-related aggression in O. smaragdina and that the brains of majors had significantly higher titres of OA than those of minors and that OA was positively and specifically correlated with the frequency of aggressive responses to non-nestmates, a key component of territorial defence.

Male fire ant neurotransmitter precursors trigger reproductive development in females after mating

It is shown that male fire ants produce tyramides, derivatives of the biogenic amine tyramine, in their reproductive system, and it is suggested that the complex inhibition/disinhibition of reproductive development described here will be applicable to other members of this ant sub-family.

Queen primer pheromone affects conspecific fire ant (Solenopsis invicta) aggression

It is proposed that the powerful effect of fire ant queens on conspecific nestmates recognition is caused by a queen-produced recognition primer pheromone that increases the sensitivity of workers to subtle quantitative differences in nestmate recognition cues.

Octopamine reverses the isolation-induced increase in trophallaxis in the carpenter ant Camponotus fellah.

It is suggested that the levels of octopamine in the brain of socially deprived ants may decrease, together with a concomitant increase in their urge to perform trophallaxis and to experience social contacts, which could be regarded as being partly responsible for the social cohesion between nestmates in ant colonies.

Queen pheromone modulates brain dopamine function in worker honey bees

This study reveals that QMP has profound effects on dopamine pathways in the brain, pathways that play a central role in behavioral regulation and motor control and identifies homovanillyl alcohol as a key contributor to these effects.

Odour convergence and tolerance between nestmates through trophallaxis and grooming in the ant Camponotus fellah (Dalla Torre)

It is demonstrated that nestmate recognition cues are exchanged between workers via trophallaxis and grooming and that they are not dominated by queen cues, two conditions that fulfil Gestalt nestmates recognition signals requirements.

Octopamine modulates honey bee dance behavior

It is shown that treatments with controlled doses of the biogenic amine neuromodulator octopamine selectively increased the reporting of resource value in dances by forager bees.

Ant Nestmate and Non-Nestmate Discrimination by a Chemosensory Sensillum

A sensory sensillum on the antennae of the carpenter ant Camponotus japonicus that functions in nestmate discrimination is described, suggesting a role for a peripheral recognition mechanism in detecting colony-specific chemical signals.

Pheromone-mediated gene expression in the honey bee brain

Results demonstrate chronic gene regulation by a primer pheromone and illustrate the potential of genomics to trace the actions of a phersomone from perception to action, and thereby provide insights into how pheromsones regulate social life.

Neurochemicals aid bee nestmate recognition

Evidence for the neurochemical modulation of nestmate recognition is provided: treatment with octopamine agonists improves the discrimination of related nestmates from unrelated non-nestmates in honeybees.
