Summary: Colonies of the monogyne social form of the red imported fire ant, Solenopsis invicta, may contain half a million workers per nest. Spatially organizing such a large group within the confines of a single nest requires a pragmatic architectural design. The morphology of field mounds and subterranean nest chambers of S. invicta were determined using several cast methods. The above-ground portion of a fire ant nest, the mound, consisted of a dense matrix of narrow tunnels. Below ground… 

Discovering the Giant Nest Architecture of Grass-Cutting Ants, Atta capiguara (Hymenoptera, Formicidae)

The architecture of three A. capiguara nests from a fragment of Cerrado in Botucatu, São Paulo, Brazil is investigated to contribute to a better understanding of the so far unknown nest architecture of this grass-cutting ant.

Testing the effect of a nest architectural feature in the fire ant Solenopsis invicta ( Hymeno ptera : Formicidae )

Testing the effect of nest subdivision on brood-rearing efficiency in laboratory nests with a single chamber or many small chambers of equal total area found no significant effect on any measure of brood rearing efficiency or final colony size.

Nest Architecture and Colony Growth of Atta bisphaerica Grass-Cutting Ants

It is demonstrated for A. bisphaerica that nest development in terms of chamber volume is similar to the increase in number of colony workers, and this contributes to a better understanding of Atta nest architecture.

Nest architecture and colony composition in two populations of Ectatomma ruidum sp. 2 (E. ruidum species complex) in southwestern Colombia

Nest architecture plays a fundamental role in the adaptation of ants to their habitat, favoring the action of economically important species. Ectatomma ruidum sp. 2 (ruidum species complex) is a

Nest architecture of the ant Formica pallidefulva: structure, costs and rules of excavation

The architecture of underground ant nests was studied in the ant Formica pallidefulva, which consist of more or less vertical shafts that bear chambers, which are top-heavy and declining exponentially with depth.

Diversity ffect of the presence of brood and fungus on the nest architecture nd digging activity of Acromyrmex subterraneus Forel ( Hymenoptera , ormicidae ) arlos

The results do not support the hypothesis that the fungus garden and/or brood are local stimuli for nest excavation or that they mold the internal architecture of the nest and the same does not apply to A. subterraneus.

The architecture of the subterranean nests of the Florida harvester ant, Pogonomyrmex badius, was studied through excavation and casting and it was found that older workers moved upward to assume positions in the upper parts of the nest, much as in the colonies from which they were taken.

Excavated substrate modulates growth instability during nest building in ants

It is found that transitions and excavation cessation follow area–response thresholds: the shape transitions take place and the digging activity stops when the dug area reaches the corresponding threshold values, which are independent of nest shape and material.

Thermoregulatory brood transport in the fire ant, Solenopsis invicta

Temperature tracking within the nest is key to understanding thermoregulatory placement of fire ant brood, as well as insight into the production of sexual brood and reproduction.



Sociometry and sociogenesis of colony-level attributes of the Florida harvester ant (Hymenoptera : Formicidae)

The seasonal patterns of colony fat reserves suggest that colonies draw on these reserves to overwinter and produce sexuals, then they rebuild the reserves during the summer, suggesting that changes in colony composition and function lead to better nutrition.

Growth and Development of Colonies of the Red Imported Fire Ant, Solenopsis invicta

A study of new colonies of Solenopsis invicta Buren showed that from their inception in early May until fall when weather stops development, the colonies had grown from a single queen and 15–20

Effects of colony-level attributes on larval feeding in the fire ant, Solenopsis invicta

Investigation of the effects of colony size and worker:brood ratio on the rate of worker-to-larva trophallaxis in the fire ant reinforced previous research demonstrating that social feeding in theFire ant emerges from localized interactions rather than mass communication.

Sociometry and Sociogenesis of Colonies of the Fire Ant Solenopsis Invicta During One Annual Cycle

Fire ant colonies reached their annual maximum population size in midwinter and their maximum biomass in spring and declined to a midsummer minimum, showing that the transition from the ergonomic to the reproductive stages is sharp, and that colonies must grow in order to produce more sexuals.

Self-organizing nest construction in ants: individual worker behaviour and the nest's dynamics

This model confirms that a surprisingly small and simple set of behavioural rules are not only sufficient for wall construction but also for the formation of one or more nest entrances, and predicts that the nests of these ants are likely to exhibit interesting dynamics, in which the tendency to build a new larger nest may lag behind growth of the population that the nest has to house.

Individual Flexibility and Tempo in the Ant, Pheidole dentata, the Influence of Group Size

This study investigates individual flexibility of foraging ants (Pheidole dentata) when the number of nestmates is altered by establishing broodless and queenless colony fragments all originating

Annual cycles in worker size of the seed-harvester antVeromessor pergandei (Hymenoptera: Formicidae)

There is little, if any, morphspecific task specialization by workers suggesting worker size variance is a colony-level adaptation permitting maintenance of a large and constant worker force during periods of resource fluctuation.

Evidence was provided in support of the hypothesis that the growth of the worker population was autocatalytic, the numbers at any time playing a large part in determining the amount of growing juvenile replacement material.

In this paper two further causes are considered: one related to the shape and character of the working group and the other to the "trial" method of feeding.

Fire ant thermal preferences: behavioral control of growth and metabolism

Thermal preferences of well-fed and food-limited fire ant colonies (Solenopsis invicta) were studied in relation to colony growth and metabolic costs, and thermal preferences for brood in food-Limited colonies did not match the food- limited growth curve.
