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 insect success in the introduced fire ant Solenopsisinvicta. Our aim was to determine if changes in social structure occurred over time and if variation in worker size was related to worker genotype. We sampled 1139 workers from five multiple-queen S. invicta nests on six dates over a one-year period… Expand

Social chromosome variants differentially affect queen determination and the survival of workers in the fire ant Solenopsis invicta
TLDR
Evidence is found that the Sb variant of the social chromosome increases the likelihood of female brood to develop into queens and that adult SB/Sb workers, the workers that cull SB/ SB queens, are overrepresented in comparison to SB/SB workers. Expand
Functional genetics and genomics in ants ( Hymenoptera : Formicidae ) : The interplay of genes and social life
Ants are among the most remarkable and successful of animal taxa. The success of ants stems from their complex social systems, which originate, in part, from the genetic composition of individualExpand
Functional genetics and genomics in ants (Hymenoptera: Formicidae): The interplay of genes and social life
TLDR
Overall, substantial progress has been made in linking molecular genetic information to phenotypic variation in ants, however, many important research opportunities related to the molecular basis of complex phenotypes remain unexploited by the ant research community. Expand
Experimental Conversion of Colony Social Organization in Fire Ants (Solenopsis invicta): Worker Genotype Manipulation in the Absence of Queen Effects
TLDR
The results support the conclusion that polygyny in S. invicta is induced by a minimum frequency of colony workers carrying the b allele, and confirm that its expression is independent of queen genotype or history, worker genotypes at genes not linked to Gp-9, and colony genetic diversity. Expand
Comparative Population Genetics of Red Imported Fire Ants (Solenopsis invicta) at the University of Central Oklahoma and Lake Arcadia, Edmond, Oklahoma
Abstract The red imported fire ant is a well-studied pest in the southern United States, but investigations of invasions in the central region are relatively rare. We compared two central OklahomaExpand
Temporal genetic structuring of a specialist parasitoid, Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae) attacking a specialist aphid on tansy
TLDR
The genetic structuring of this insect is very fine grained and the temporal genetic diversity is explained by a combination of extinction and recolonization events, as well as inbreeding. Expand
Introduction history and genetic diversity of the invasive ant Solenopsis geminata in the Galápagos Islands
TLDR
The genetic structure and diversity of populations of S. geminata in the Galápagos Islands are characterized and the archipelago colonization is unravelled by combining Bayesian clustering methods and coalescent-based scenario testing. Expand
Alternative reproductive tactics in the ant genus Hypoponera
TLDR
This long-term study reports strong seasonality in sexual production with two separated mating seasons in early and late summer, and a more male-biased allocation ratio for wingless reproductives demonstrates the greater importance of local resource competition. Expand
Behavioral Discrimination between Monogyne and Polygyne Red Fire Ants (Hymenoptera: Formicidae) in their Native Range
TLDR
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. Expand
Lack of genetic structuring, low effective population sizes and major bottlenecks characterise common and German wasps in New Zealand
TLDR
Insight is provided into the genetics of invasive Vespula wasps that can be useful for the development of efficient management strategies and encourage further research into mechanisms that promote the success of invasive social insects. Expand

The Breeding System of the Fire Ant Solenopsis invicta: Effects on Colony Genetic Structure
  • K. Ross
  • Medicine, Biology
  • The American Naturalist

TLDR
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. Expand

TLDR
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.

Population genetics and history of the introduced fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), in Australia
TLDR
It is found that both Australian infestations were more similar to North American populations than to South American, though the Fisherman Islands infestation was intermediate, making it difficult to assign. Expand
GENETIC ANALYSIS OF DISPERSAL DYNAMICS IN AN INVADING POPULATION OF ARGENTINE ANTS
TLDR
The results show that the genetic structure of nests was not homogenous across unicolonial populations, indicating that nests are most closely related to neighboring nests and that the expansion of subpopulations is primarily due to the local budding of new nests from existing nests at the invasion front. Expand
Effects of a single gene on worker and male body mass in the fire ant Solenopsis invicta (Hymenoptera : Formicidae)
TLDR
It is found that Gp-9 genotype was significantly associated with variation in worker mass in field but not laboratory colonies, and polygyne males were significantly lighter than monogyne males, indicating that social environment interacts with G p- 9 genotype to influence male mass. Expand
Multilocus evolution in fire ants: effects of selection, gene flow and recombination.
  • K. Ross
  • Biology, Medicine
  • Genetics
  • 1997
TLDR
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. Expand
A FORMAL ASSESSMENT OF GENE FLOW AND SELECTION IN THE FIRE ANT SOLENOPSIS INVICTA
TLDR
A novel mathematical model is constructed and analyzed to delimit the effects of monogyne male gene flow and selection on the joint genotypes at the Pgm‐3/Gp‐9 superlocus and found that selection on polygyne queens and workers alone provides the most parsimonious explanation for the observed genotype frequencies. Expand
Polymorphism at dinucleotide microsatellite loci in fire ant Solenopsis invicta populations
TLDR
The fire ant Solenopsis invicta has emerged as a case study for investigating the consequences of variation in social organization for the evolution of individual phenotypes, patterns of gene flow and routes to possible speciation, and microsatellite markers were developed with the hope that these markers would be more polymorphic than the protein-encoding loci. Expand
Queen recruitment in a multiple-queen population of the fire ant Solenopsis invicta
TLDR
Queen recruitment in this population of S. invicta appears to occur at random with respect to the number of older queens present within nests, suggesting that newly recruited queens represent a random sample of potential reproductive queens in the population. Expand
GENETIC ORIGIN OF MALE DIPLOIDY IN THE FIRE ANT, SOLENOPSIS INVICTA (HYMENOPTERA: FORMICIDAE), AND ITS EVOLUTIONARY SIGNIFICANCE
  • K. Ross, D. Fletcher
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1985
TLDR
Three hypotheses are proposed, based on current knowledge of sex‐determining mechanisms in the Hymenoptera, to explain the loss of genetic diversity associated with high rates of diploid male production in S. invicta: allelic diversity was reduced during colonization of North America by a small founder group, genetic structuring of polygyne populations due to local inbreeding caused reduced allelic Diversity and/or increased homozygosity.
