Restricted effective queen dispersal at a microgeographic scale in polygynous populations of the ant Formica exsecta [PDF]
, 2001 Ecological constraints on effective dispersal have been suggested to be a key factor influencing social evolution in animal societies as well as the shift from single queen colonies (monogyny) to multiple queen colonies (polygyny) in ants.

Alternative reproductive strategies: a queen perspective in ants [PDF]
, 2000 Ant colonies are commonly thought to have a stable and simple family structure, with one or a few egg-laying queens and their worker daughters. However, recent genetic studies reveal that the identity of breeding queens can vary over time within colonies.

Loss of Wolbachia infection during colonisation in the invasive Argentine ant Linepithema humile [PDF]
, 2005 WOLBACHIA are maternally inherited bacteria, which are very common in arthropods and nematodes. Wolbachia infection may affect host reproduction through feminisation, parthenogenesis, male-killing, cytoplasmic incompatibility and increased fecundity ...

Control of Solenopsis invicta (Hymenoptera: Formicidae) with Teflubenzuron
The Florida Entomologist, 1997 Teflubenzuron baits were active against laboratory colonies of the red imported fire ant, Solenopsis invicta Buren. Worker brood production ceased soon after treatment and by four weeks posttreatment, most colonies were devoid of brood. Worker ants did not exhibit any direct effects from treatment with teflubenzuron.

The Organization of Foraging in the Fire Ant,Solenopsis invicta [PDF]
Journal of Insect Science, 2011 Although natural selection in ants acts most strongly at the colony, or superorganismal level, foraging patterns have rarely been studied at that level, focusing instead on the behavior of individual foragers or groups of foragers. The experiments and observations in this paper reveal in broad strokes how colonies of the fire ant, Solenopsis invicta ...
