A multidisciplinary approach to discriminating different taxa in the species complex Pachycondyla villosa (Formicidae)
A multidisciplinary approach provides new evidence that strongly supports the differentiation of three taxa previously confounded in a single species, Pachycondyla villosa. All specimens studied wereExpand

Hydrocarbon circulation and colonial signature in Pachycondyla villosa.
In ants, both cuticular and postpharyngeal gland (PPG) hydrocarbons (HCs) have been involved in nestmate recognition. However, no detailed comparison is available. A comparative study including alsoExpand

Role of cuticular hydrocarbons in the chemical recognition between ant species in the Pachycondyla villosa species complex.
Cuticular hydrocarbons (HCs) play important roles in insect communication but few studies clearly demonstrate the direct link between HCs and nestmate recognition. Therefore, cuticular lipids wereExpand

Individual foraging and path fidelity in a ponerine ant
SummaryAn investigation of field foraging in colonies ofNeoponera apicalis is reported. We observed that workers develope an individualized foraging strategy with a high degree of regionalExpand

Worldwide invasion by the little fire ant: routes of introduction and eco-evolutionary pathways
Biological invasions are generally thought to occur after human aided migration to a new range. However, human activities prior to migration may also play a role. We studied here the evolutionaryExpand

Dynamics of aggregation in Lasius niger (Formicidae): influence of polyethism
SummaryPolyethism is a well-known phenomenon in social insects. How this phenomenon influences interactions among individuals, the spatial distribution in the nest is, on the other hand, very rarelyExpand

How an Ant Manages to Display Individual and Colonial Signals by Using the Same Channel
Cuticular hydrocarbons are used by some ants to discriminate nestmates from nonnestmates. Every member of the colony bears the same pattern because they are continuously exchanged among nestmates.Expand

Small queens in the ant Ectatomma tuberculatum: a new case of social parasitism
Social parasites exploit the worker force of colonies of other social insects to rear their own young. Social parasitism occurs in several Hymenoptera and is particularly common in several tribes ofExpand
