Division of labor is fundamental to the success of all societies. The most striking examples are the physically polymorphic worker castes in social insects with clear morphological adaptations to different roles. These polymorphic worker castes have previously been thought to be a classic example of nongentically controlled polymorphism, being mediated entirely by environmental cues. Here we show that worker caste development in the leaf-cutting ant Acromyrmex echinatior has a significant…

Genetic polymorphism in leaf-cutting ants is phenotypically plastic

A plastic genetic influence on division of labour has thus evolved convergently in two distantly related polyandrous taxa, the leaf-cutting ants and the honeybees, suggesting that it may be a common, potentially adaptive, property of complex, genetically diverse societies.

A genetic component in the determination of worker polymorphism in the Florida harvester ant Pogonomyrmex badius

It is demonstrated that the determination of worker castes in the strongly polyandrous Florida harvester ant, Pogonomyrmex badius, has a genetic component and the results suggest that workers of different patrilines in P. badius differ significantly in their propensities to develop into a certain worker caste.

Genetic caste polymorphism and the evolution of polyandry in Atta leaf-cutting ants

It is shown for the first time that there is a significant genetic influence on worker size in Atta colombica leaf-cutting ants and that Atta are more polyandrous than previously thought, adding weight to the hypothesis that division of labour is a potential driver of the evolution of polyandry.

Random sperm use and genetic effects on worker caste fate in Atta colombica leaf‐cutting ants

It is demonstrated that fertilization success is directly related to sperm numbers, that stored sperm are well‐mixed and that egg paternity is constant over time, and that genetic variation for caste can persist in societies with comparatively high relatedness.

The causes and consequences of genetic caste determination in ants (Hymenoptera: Formicidae)

The evolutionary dynamics of genetic caste determination involves the coevolution (often antagonistic) of biasing and restorer genes expressed in interacting nestmates, which may lead to widespread dependent lineage systems, sperm parasitism, and workerless social parasites.

Behavioral regulation of genetic caste determination in a Pogonomyrmex population with dependent lineages.

It is shown that queens in young colonies produce both interlineage and intralineage eggs, demonstrating that queens of GCD colonies indiscriminately use sperm of at least two lineages to fertilize their eggs, and that workers may cull these eggs when colonies are not producing queens.

Patriline shifting leads to apparent genetic caste determination in harvester ants

Apparent caste determination may result from temporal variation in sperm use, rather than from fertilization bias among male ejaculates, and be a consequence of processes that reflect sexual conflict, such as sperm clumping.

Caste-specific expression of genetic variation in the size of antibiotic-producing glands of leaf-cutting ants

There were significant positive relationships between the gland sizes of patrilines in the different castes, indicating that the genetic mechanism underpinning the patriline variation has remained similar across phenotypes, consistent with the hypothesis that there is individual selection on disease defence in founding queens and colony-level selection in the worker castes.

Causes and consequences of genetic caste-bias in the eusocial Hymenoptera

Genotypic differences in the physiological response to environmental cues may underlie genetic caste-bias in the social insects, and this work shows that understanding the interaction between physiology, environment and genotype is essential if the authors are to understand the ultimate determinants of individual caste fate.



Extreme genetic differences between queens and workers in hybridizing Pogonomyrmex harvester ants

Data is presented demonstrating unexpected genetic differences between reproductive castes in a variant of the rough harvester ant, Pogonomyrmex rugosus var.

Genetic determination of the queen caste in an ant hybrid zone

The question of how reproductives and sterile workers differentiate within eusocial groups has long been a core issue in sociobiology because it requires the loss of individual direct fitness in

Genetic basis for queen–worker dimorphism in a social insect

It is hypothesize that the system of caste determination that is observed in the red harvester ant, Pogonomyrmex barbatus, segregates the population into two distinct genetic lineages, each of which has distinct alleles at the microsatellite locus and also has different alleles, it is proposed, at caste.

Genetic influence on caste in the ant Camponotus consobrinus

Evidence indicates genetic rather than environmental causes for the observed differences between families, and it is speculated that this variation may reflect some selective advantage to within-colony heterogeneity between families or that selective differences are few between a wide array of family growth patterns.

Genetic determination of guarding and undertaking in honey-bee colonies

The results, which support the first requirement of the darwinian model for the evolution of colony organisation, suggest that the genetic structure of an insect society plays a fundamental, and previously unrecognized, role in the division of labour.

Lack of patriline-specific differences in chemical composition of the metapleural gland secretion in Acromyrmex octospinosus

This work uses the leaf-cutting ant Acromyrmex octospinosus to specifically test the hypothesis that genetically more diverse worker-offspring produce a more variable spectrum of metapleural gland compounds, and uses DNA microsatellite markers to assign workers from two colonies to the six most common patrilines in each colony.

The Developmental Basis of Worker Caste Polymorphism in Ants

In ants, the simplest developmental switch, revision of critical size alone, does not lead to discontinuous phenotypes, and only when changes in growth rules are tied to the decision to revise critical size are distinct phenotypes produced from the alternative developmental programs.

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.
