A large microsatellite survey of fire ants of both social forms (monogyne and polygyne) from both the native and introduced ranges (Argentina and the U.S.A.) revealed surprisingly high levels of triploidy (12%) in non-reproductive females from an introduced polygyne population in Georgia, U.S.A. Triploid females were not detected among reproductive (egg-laying) queens from this population, among females from monogyne populations in the introduced range or among females of either social form… 

Evidence of Selective Mating and Triploidy Among Two Social Forms of Solenopsis invicta (Hymenoptera: Formicidae)

This study examined the genotypes of queens and their stored sperm during a mating flight in Florida where polygyne colonies predominate, and provides evidence of non-random mating.

Triploid bumblebees indicate a direct cost of inbreeding in fragmented populations

For both species, triploid frequency was negatively correlated with surrogates of population size, providing direct evidence for inbreeding in small populations.

This is the first study to investigate the population and colony structure of fire ants in Taiwan and results represent an important contribution to the ongoing efforts aimed at eradicating this invasive pest.

Population structure and mating biology of the polygynous ponerine ant Gnamptogenys striatula in Brazil

It is suggested that new nests are founded by budding in G. striatula, a polygynous ponerine ant, whose colonies contain either several differentiated queens or several gamergates, which suggests that mating frequency is low in this population.

Sib‐mating in the ant Plagiolepis pygmaea: adaptative inbreeding?

The data show that workers actively repel unrelated males entering their colony, and that queens preferentially mate with related males, consistent with inclusive fitness being a driving force for inbreeding: by preventing outbreeding, workers reduce erosion of relatedness within colonies due to polygyny and polyandry.

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.

Strategies of the invasive tropical fire ant (Solenopsis geminata) to minimize inbreeding costs

Investigating how inbreeding affects colony founding and potential strategies to overcome its effects in the invasive tropical fire ant, Solenopsis geminata revealed that pleometrosis and cannibalism of diploid male larvae represent strategies through which invasive ants can successfully establish despite high inbreeding.

The introduction history of P. chinensis antennalis in New Zealand is probably the result of at least two independent introductions, passing through a bottleneck during introduction, followed by population expansion from the point of introduction.

Genetic and morphological variation over space and time in the invasive fire ant Solenopsis invicta

Social insects are among the most successful and damaging of invasive taxa. We studied spatial and temporal variation in two traits, colony genetic structure and worker mass, associated with social

Inbreeding in a natural population of Euodynerus foraminatus (Hymenoptera: Vespidae), a solitary wasp with single‐locus complementary sex determination

The data suggest that a mixture of inbreeding and outbreeding persists in E. foraminatus despite the presence of sl‐CSD, and between 55% and 77% of the matings in this population take place between siblings.

Effect of a founder event on variation in the genetic sex-determining system of the fire ant Solenopsis invicta.

It is concluded that diploid males have increased in frequency in introduced populations because of a loss of allelic diversity at the sex-determining locus (loci) of S. invicta, which has generated a substantial increase in the estimated segregational genetic load associated with production of sterile diploids males in introducing populations over the load in native populations.

Significant differences within nests in the matrilineal composition of worker and queen brood are revealed, constituting further evidence for inequities among nest-mate queens in the allocation of their progeny to the two castes at a single point in time.

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.

Multilocus evolution in fire ants: effects of selection, gene flow and recombination.

Evidence is presented that selection acting independently on Pgm-3 and Gp-9, in conjunction with gene flow from the alternate, "monogyne" social form of this species, may explain the origin of disequilibrium between the two loci in polygyne fire ants.

Protein electrophoresis was used to determine the source and diversity of clones in a freshwater snail in four glacial lakes in which sexual and clonal females were thought to coexist, and showed that repeated mutation to parthenogenetic reproduction since the Pleistocene has introduced a different and diverse set of clone in all four lakes.
