Abstract Queen mating frequency of the facultatively polygynous ant Acromyrmex echinatior was investigated by analysing genetic variation at an (AG)n repeat microsatellite locus in workers and sexuals of 20 colonies from a single Panamanian population. Thirteen colonies were found to be monogynous, 5 colonies contained multiple queens, whereas the queen number of 2 colonies remained unresolved. Microsatellite genotypes indicated that 12 out of 13 queens were inseminated by multiple males… 

Multiple paternity, relatedness and genetic diversity in Acromyrmex leaf–cutter ants

It is reported the first case of an ant species where multiple mating reduces relatedness among female offspring to values significantly lower than 0.5, which is contrary to the positive relationship between queen–mating frequency and colony size found across more distantly related ant species.

Biased sperm use by polyandrous queens of the ant Proformica longiseta

The results indicated that diploid male load, sperm limitation and sex ratio conflict are also unlikely explanations of polyandry.

Distribution and origin of intraspecific social variation in the California harvester ant Pogonomyrmex californicus

A correlation between pleometrosis in incipient colonies and polygyny in adult colonies at the population level is demonstrated, and it is strongly suggested that the same occurs in nature.

Determinants of intracolonial relatedness in Pogonomyrmex rugosus (Hymenoptera; Formicidae): mating frequency and brood raids

The available mating frequency data and phylogenetic information of the genus Pogonomyrmex suggest that multiple mating is the ancestral state in the North American Pogonomarymex sensu stricto.

Population- and sociogenetic structure of the leaf-cutter ant Atta colombica (Formicidae, Myrmicinae)

Multiple mating and long-distance dispersal appear to be two interconnected behavioural mechanisms to create and maintain genetic diversity in At.

Extremely high mating frequency in the Florida harvester ant (Pogonomyrmex badius)

It is now clear that all major sub-clades of Pogonomyrmex sensu stricto exhibit high levels of polyandry, and multiple mating must have arisen early in the evolution of the genus, and may have constituted a mechanism to increase offspring variability for queens that were confronted with increasingly complex levels of organization.

Decoupled evolution of mating biology and social structure in Acromyrmex leaf-cutting ants

It is suggested that multi-queen nesting and mating frequency evolve independently of one another, indicating that behavioral and ecological factors other than genetic diversity contribute to the evolution of complex mating behaviors in leaf-cutting ants.

Intraspecific support for the polygyny‐vs.‐polyandry hypothesis in the bulldog ant Myrmecia brevinoda

It is suggested that the high costs of multiple matings and the strong effect of multiple mating on intracolonial genetic diversity may be essential to the negative association between polygyny and polyandry and that any attempt to empirically test this hypothesis should place emphasis upon these two key underlying aspects.

Polyandry in two South American harvester ants

It is suggested that multiple mating probably arose early in the evolution of the genus Pogonomyrmex and may be the basis of its ecological success and wide distribution.

Polygyny and polyandry in small ant societies

A new taxon in social Hymenoptera with high queen‐mating frequencies and with intriguing mating and dispersal patterns of the sexuals is found, found in two closely related Neotropical ant species P. inversa and P. villosa.

Multiple paternity in the leafcutter ant Atta colombica — a microsatellite DNA study

The results confirm previous nongenetic studies showing high levels of multiple mating by queens of higher leafcutter ants, and discuss the findings in relation to known patterns of polyandry and paternity in other eusocial Hymenoptera.

Multiple mating in the ant Acromyrmex versicolor: a case of female control

It is argued that the best hypothesis to explain polyandrous mating and complete sperm mixing in A. versicolor is that utilizing genetically diverse sperm confers a selective advantage on females.

GENETIC VARIABILITY, QUEEN NUMBER, AND POLYANDRY IN SOCIAL HYMENOPTERA

It seems that the causal relationship underlying this association is that the number of matings by queens depends on thenumber of queens present in the colony, which supports the GV hypotheses together with the assumption that mating has costs.

Diploid males and colony-level selection in Formica ants

Models of the load hypothesis suggest that slow growth and high mortality of colonies with diploid males favour single mating by queens, and the longer the period of slow colony growth and the heavier the mortality, the stronger is the selection for monandry.

Precise assessment of the number of patrilines and of genetic relatedness in honeybee colonies

It is shown that the genetic structure of the A. mellifera colony remained largely unchanged over time as long as the colony is headed by the same queen, and the genetic diversity within the colony provided a good estimate of the genetic Diversity of the local honeybee population.

Polyandry in the genus Apis, particularly Apis andreniformis

Using four polymorphic microsatellite loci, it is found that four Apis andreniformis queens collected in Thailand each mated at least 10–20 times, producing an average relatedness, gww, of workers, and the extreme polyandry observed in Apis.

Multiple mating increases the sperm stores of Atta colombica leafcutter ant queens

The “multiple-mating-for-more-sperm” hypothesis on individual young queens in a natural population of the leafcutter ant Atta colombica, a monogynous ant characterised by very large colonies and high colony longevity, was found to be positively correlated with the number of mates per queen estimated through mother-offspring analysis with microsatellite DNA markers.

Paternity in eusocial Hymenoptera

It is concluded that reliably documented high paternity or insemination frequencies (> 2) are currently restricted to one phylogenetically isolated and highly eusocial taxon each in ants, eussocial bees and wasps (Atta, Apis and Vespula, respectively).

Polyandry and allele frequency differences between the sexes in the ant Formica aquilonia

Genetic mother-offspring analyses based on six enzyme gene loci show that about 60 per cent of the females of the mound-building red wood ant Formica aquilonia mate with several males, indicating normal Mendelian inheritance at these loci and the difference between the sexes seem likely to result from selection.
