Abstract Although colonies of the fire ant Solenopsis invicta are often founded by small groups of queens, all but one of the queens are soon eliminated due to worker attacks and queen fighting. The elimination of supernumerary queens provides an important context for tests of discrimination by the workers, since the outcome of these interactions strongly affects the workers' inclusive fitness. To test whether workers in newly founded colonies discriminate among nestmate queens, paired… 

Bourgeois queens and high stakes games in the ant Aphaenogaster senilis

This work investigated the importance of physical dominance in queen selection in orphaned groups by manipulating the fighting ability of first-born queens via mandibular ablation, and found first emerged queens were heavier than second emerged queens, performed almost all aggression, and were behaviourally dominant 92% of the time.

Conditions favoring queen execution in young social insect colonies

Using a game theoretical model, a series of decision rules are suggested that are consistent with the current experimental evidence from study of young colonies of the fire ant Solenopsis invicta, suggesting that workers should delay aggression against extra queens until the workers can gain their greatest advantage through such aggression.

Selfish strategies and honest signalling: reproductive conflicts in ant queen associations

A brood transfer experiment is used to test whether cofounding queens of the ant Lasius niger ‘selfishly’ adjust their productivity when sharing the nest with future competitors, highlighting the role of honest signalling in the evolution of cooperation.

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.

Experimental investigations of inclusive fitness theory in a multiple-queen ant

Overall, for workers as a whole, I found no evidence for within-colony kin discrimination in the context of workers' individual treatment of queens in polygynous L. acervorum colonies.

Policing in queenless ponerine ants

This work reviews worker and "queen" policing in queenless ponerine ants and extends the definition of policing to include species, such as queenless ants, where females are totipotent, thereby including not only conflict over male production but also over gamergate replacement and gamergate number.

Ants in Flight: Reproduction, Dispersal and Predation of Ant Queens

It is suggested that a model based approach to colony design and management should be considered rather than a straightforward one-size-fits-all approach.

The flight ecology of ants (Hymenoptera: Formicidae)

Flight tradeoffs explain much variation in ant life history, including the temporal segregation of flight and egg production, the continuum of ant mating systems from male aggregation to female calling syndromes, and the evolution of alternate colony founding strategies.



The dissolution of cooperative groups: mechanisms of queen mortality in incipient fire ant colonies

Competition between foundress queens of the fire ant Solenopsis invicta is examined to suggest that queen survival is promoted by a high fighting ability relative to co-foundresses, rather than by increased worker production, and that workers respond to queen differences that are independent of kinship.

Reproductive conflicts in cooperative associations of fire ant queens (Solenopsis invicta)

Two factors, the queens' relative fighting ability and their relative contribution to worker production (assuming that workers can recognize and selectively favour their mother) have been proposed to influence the survival prospects of individual queens within associations and the effect was tested in the fire ant Solenopsis invicta.

Colony founding by queen association and determinants of reduction in queen number in the ant Lasius niger

Queens in this study avoided areas frequented by workers of established colonies, leading to additional clumping of nest foundations, indicating that foundress associations are facultative, promoted by crowding and intense intercolony competition.

Colony Founding by Queens of the Red Imported Fire Ant, Solenopsis invicta

The method by which newly mated queens of the red imported fire ant, Solenopsis invicta Buren, found new colonies was investigated and optimum temperature was found to be between 27.5 and 32°C.

Intraspecific usurpation of incipient fire ant colonies

The hypothesis that workers abandon their natal colony after losing a brood raid to increase the likelihood that their queen can usurp the colony to which they migrate is supported, and colonies of ants founded by several queens are better able to resist usurpation attempts.

Brood Raiding in the Fire Ant, Solenopsis invicta (Hymenoptera: Formicidae): Laboratory and Field Observations

Rec reciprocal brood raiding took place along odor trails connecting various numbers of nests from a few centimeters to 20 m apart, and its effect was to aggregate the brood and workers from local populations of incipient colonies into a few locations.

Worker Control of Queen Density in Hymenopteran Societies

The following model illustrates how worker control of queen density and matricide might evolve in the absence of genetic odor recognition.

Lack of detectable nepotism in multiple-queen colonies of the fire ant Solenopsis invicta (Hymenoptera: Formicidae)

It is argued that the non-nepotistic strategies displayed by these ants reflect historical selection pressures experienced by native populations, in which nestmate queens are highly related to one another.

Social control of egg‐laying rate in queens of the fire ant, Solenopsis invicta*

Either the logarithmic relation of fecundity to larval numbers or physical limits of the queen may set the maximum egg‐laying rate, and thus determine maximum colony size, and the data do not allow a clear choice between these alternatives.

An experimental study of pleometrotic colony founding in the fire ant, Solenopsis invicta : what is the basis for association?

Overall, this study suggests that newly mated queens are under strong selection to leave the soil surface and do so by using any available holes, whether dug by another queen or of some other origin; they are attracted to other queens, and are more likely to cofound as contact with the potential cofoundress becomes more frequent.
