Abstract The Argentine ant, Linepithema humile (Mayr), and the red imported fire ant, Solenopsis invicta Buren, are natural agonists in their country of origin. Since the first report of L. humile in California in 1907 its range expanded statewide, displacing native ant species wherever it spread. Since the discovery of established populations of S. invicta in southern California in 1998, it has been restricted to discrete areas of southern California. However, as these discrete populations… 

Chemical Defense by the Native Winter Ant (Prenolepis imparis) against the Invasive Argentine Ant (Linepithema humile)

It is hypothesized that this chemical defense may help P. imparis to resist displacement by L. humile and is found that in aggressive interactions between the two species, P.Imparis employs a potent defensive secretion.

Interspecific Competition between Solenopsis invicta and Two Native Ant Species, Pheidole fervens and Monomorium chinense

It is found that the viral infection weakened the competitive ability of S. invicta and made them prone to be eliminated by M. chinense but not by P. fervens.

Incidence of Aggressive Territoriality between Two Ant Species: Camponotus compressus Fab. and Oecophylla smaragdina Fab. (Hymenoptera:Formicidae)

This incident was encountered in an old, neglected mango orchard on the outskirts of Bengaluru, India, between two species of ants, Camponotus compressus Fabricius and Oecophylla smaragdina Fabricius, leading to mortality in both species.

Induced Disturbances Cause Monomorium pharaonis (Hymenoptera: Formicidae) Nest Relocation

The results provide useful information about the causes of Pharaoh ant colony budding and guidance about how to develop effective control and prevention strategies, and moisture depletion did not show any significant effect on colony movement.

Long-term coexistence of two invasive vespid wasps in NW Patagonia (Argentina)

In Patagonia (Argentina) two non-native vespid wasps became established in the last decades. Vespula germanica was first detected in 1980, while V. vulgaris arrived some 30 years later. Both species

Aggression in imported fi re ants : an explanation for shifts in their spatial distributions in Southern United States ?

1. The imported fire ants, Solenopsis invicta Buren (red), S. richteri Forel (black), and their hybrids ( S. invicta × S. richteri ) are sympatric congeners with overlapping but shifting spatial

The Native Ant Lasius niger Can Limit the Access to Resources of the Invasive Argentine Ant

Assessment of the competitive behavior of the invasive Argentine ant when facing another invasive species or a native dominant species suggests that a native species could impact invasive populations of the Argentine ant by interference competition, perhaps better so than some invasive species.

Repellency of Five Essential Oils to Linepithema humile (Hymenoptera: Formicidae)

Abstract Laboratory bioassays were performed to test the repellent properties of 5 plant-extracted essential oils against the Argentine ant, Linepithema humile (Mayr). Three concentrations (0.10%,

Quantification of supercolonial traits in the yellow crazy ant, Anoplolepis gracilipes

This research has demonstrated that A. gracilipes displays supercoloniality equivalent to that of the well-studied Argentine ant Linepithema humile, and quantification of these traits is required for other supercolonial species to improve understanding of this social strategy.



Ability of Resident Ants to Destruct Small Colonies of Solenopsis invicta (Hymenoptera: Formicidae)

Analysis of the aggressive interaction between selected resident ants and S. invicta suggests that the native ant species Monomorium minimum, Pheidole dentata Mayr, and Solenopsis molesta and exotic tramp ants Tetramorium bicarinatum and MonOMorium pharonis do interact with the S.Invicta and will attack and eliminate worker-defended S. Invicta colonies.

Invasive interactions of Monomorium minimum (Hymenoptera:Formicidae) and solenopsis invicta (Hymenoptera:Formicidae) infected with thelohania solenopsae (Microsporida:Thelohaniidae) in the laboratory

S. solenopsae were not able to defend their colony or prevent competing ants from invading as well as uninfected S. invicta colonies, and M. minimum was the more invasive species when compared to S. Invicta.

Invasion of Polygyne Fire Ants Decimates Native Ants and Disrupts Arthropod Community

The ecological impacts of a polygyne fire ant invasion on ants and other surface—active arthropods at a field station in central Texas indicate that polygyn fire ants pose a substantial threat to the biodiversity of native arthropod communities.

Division of labor in fire ants based on physical castes (Hymenoptera: Formicidae: Solenopsis).

?Division of labor in two species of fire ants, Solenopsis invicta and S. geminata, was studied by a "cross-indexing" method that employed (1) the description of the total behavioral repertory of


The findings imply that Argentine ants secure a majority of available food resources where this species comes into contact with native ants, and may be able to break the competitive trade-off constraining native ants because of their unique colony structure and because they have escaped their natural enemies.

Behavioral interactions of the invasive Argentine ant with native ant species

Interactions between Argentine ants and native species at food resources, causing ants of native species to retreat, may help Argentine ants to displace native species from invaded areas.

Effect of Horizontal Transfer of Barrier Insecticides to Control Argentine Ants (Hymenoptera: Formicidae)

Abstract Horizontal transfer of three contact insecticides, bifenthrin, β-cyfluthrin, and fipronil, was tested in laboratory colonies. Donor ants were exposed for 1 min to insecticide-treated sand

The role of resource imbalances in the evolutionary ecology of tropical arboreal ants

Dietary ratios of CHO:protein play an important and previously unrecognized role in the ecology and evolution of ants generally and modifications of worker digestive systems in certain ant sub-families and genera represent key innovations for handling and processing large volumes of liquid food.

Gaster flagging by fire ants (Solenopsis spp.): Functional significance of venom dispersal behavior

Observations suggest that airborne venom dispersal by workers is context specific rather than temporal caste specific and that workers can control the quantity of venom released.

Indirect effects of phorid fly parasitoids on the mechanisms of interspecific competition among ants

South American Pseudacteon phorids may be promising biocontrol agents of imported fire ants, S. invicta, in the USA because of the relatively large indirect effects.
