Genetic and observational data are combined to describe the breeding system in a polygyne population of Solenopsis invicta using a formal theoretical framework that links properties of the breeding system with colony genetic structure. Queens of S. invicta mate only once, and the study population is outbred. The number of mated queens per nest is variable but generally low, with the average relatedness of nest-mate queens indistinguishable from zero. The genetic data are sufficiently complete… 

Extended family structure in the ant Formica paralugubris: the role of the breeding system

It was estimated that about 99.8% of the reproducing queens and males originated from within the nest, or from a nearby nest, and contrast with the common view that unicoloniality is coupled with unrestricted gene flow among nests.

Population genetics of the socially polymorphic ant Formica podzolica

It is found that there is no significant differentiation between the sympatric social forms of F. podzolica, nor did differentiation among populations appear to be affected by colony social organization, and unexpected patterns of genetic structure may have resulted from differences either in the spatial distribution of the social forms or in their social flexibility.

Habitat age, breeding system and kinship in the ant Formica fusca

The results showed that both the mating system and colony kin structure differed between the study populations, and the number of queens per colony appeared more stable between years, although queen turnover occurred also in this population.

Colony kin structure and breeding system in the ant genus Plagiolepis

Both the occurrence of multiple queens (polygyny) and multiple mating (polyandry) decrease within‐colony relatedness, while mating among sibs increases relatedness between the workers and the brood they rear.

Investigation of the population genetic structure and mating system in the ant Pheidole pallidula

It is demonstrated, through analysis of mother–offspring combinations and the use of direct sperm typing, that each queen is inseminated by a single male, and it is indicated that colonies are genetically differentiated and form a population exhibiting significant isolation‐by‐distance, suggesting that some colonies originate through budding.

A TEST OF QUEEN RECRUITMENT MODELS USING NUCLEAR AND MITOCHONDRIAL MARKERS IN THE FIRE ANT SOLENOPSIS INVICTA

The results suggest that nonnestmate queen recruitment occurs at a high frequency in introduced populations of this species and kin selection models that rely on the recruitment of only nestmate queens to explain the persistence of polygyny in ants do not apply to polygyne S. invicta in its introduced range.

Multiple Queens in Ant Nests: Impact on Genetic Structure and Inclusive Fitness

It is concluded that the nest is the functional unit of selection for these populations of Leptothorax longispinosus, and across nests, there appears to be consistent, strong, stabilizing selection for intermediate levels of polygyny in two northern populations.

Genetic analysis of colony structure in polydomous and polygynous ant populations

Three methods to solve the identification of colonies problem are presented: rare genotype sisterhoods, G -distance (a measure of genotypic heterogeneity derived from G -statistics), and neighbour relatedness (estimates of genetic relatedness for specific nest pairs).

The success of alternative reproductive tactics in monogyne populations of the ant Solenopsis invicta: significance for transitions in social organization

This strategy is incorporated into an existing theoretical framework that was developed to explain the evolution of alternative social organizations in ants, providing testable predictions regarding the distribution and frequency of queen adoption in other single-queen ant societies.

Reproductive specialization in multiple-queen colonies of the ant Formica exsecta

In polygynous (multiple queens per nest) colonies of social insects, queens can increase their reproductive share by laying more eggs or by increasing the proportion of eggs that develop into

Differences in inhibitory capability among queens of the ant Solenopsis invicta

Comparisons of the abilities of various categories of queens of the fire ant to inhibit de‐alation by virgin queens are compared by means of a standardized bioassay that detects the presence of an inhibitory pheromone to determine the degree of ovarian development of different queen categories.

Colony Reproduction by Budding in the Polygyne Form of Solenopsis invicta (Hymenoptera: Formicidae)

The total weights of the colonies increased about four times during the course of the study, indicating substantial growth of colonies in addition to active budding in polygyne colonies of the red imported fire ant.

Effect of queen number on the production of sexuals in natural populations of the fire ant, Solenopsis invicta

The negative relationship between queen number and number ofSexuals provides evidence that queen control over the production of sexuals, previously established in laboratory experiments, also occurs under natural conditions.

Monogyny and Polygyny in the Fire Ant, Solenopsis invicta

All the queens of the 15 polygynous colonies were less physogastric than queens of monogynous colonies, and individually they laid far fewer eggs, but collectively they produced a significantly greater number of eggs per colony.

Genetic Relatedness in Colonies of Tropical Wasps with Multiple Queens

Estimates of within-colony relatedness for three species in this group confirm that it is sometimes (but not always) very low, and the hypothesis that inbreeding may raise relatedness is not supported.

Efficiency of Sperm Use in Queens of the Fire Ant, Solenopsis invicta (Hymenoptera: Formicidae)

Estimates of fire ant sperm-use efficiency are about 10 times higher than those reported for honey bee queens and astronomically high than those of most nonsocial animals, suggesting efficient use of sperm is an important reproductive capability for S. invicta and other social insects with high reproductive outputs.

QUEEN NUMBER IN COLONIES OF SOCIAL HYMENOPTERA AS A KIN‐SELECTED ADAPTATION

It is proposed that queen number is an ecologically flexible trait that is influenced by a broad set of factors but is not necessarily linked to specific habitat types.

Polyandry in Honey Bees (APIS MELLIFERA L.): Sperm Utilization and Intracolony Genetic Relationships.

Sperm usage by queen honey bees was examined by progeny analyses using six phenotypically distinct genetic markers and there is no evidence for elevated relatedness among colony subfamilies due to nonrandom fluctuations in sperm usage by queens or for numerical dominance of any subfam families.

Genetic specialists, kin recognition and nepotism in honey-bee colonies

Evidence is provided for competition among workers of the honey bee, Apis mellifera, in the production of female reproductives, a consequence of the genetic structure of colonies resulting from polyandry, genotypic biases in components of cooperative behaviour associated with division of labour, and kin recognition.
