A unique strategy of host colony exploitation in a parasitic ant: workers of Polyrhachis lama rear their brood in neighbouring host nests

  title={A unique strategy of host colony exploitation in a parasitic ant: workers of Polyrhachis lama rear their brood in neighbouring host nests},
  author={Ulrich Maschwitz and Carlo Go and Eva Kaufmann and Alfred Buschinger},
The formicine ant Polyrhachis lama is a social parasite, exploiting its ponerine host ant species Diacamma sp. In most social parasitic associations, the parasitic species are closely related to their host species group, evolving directly from independent ancestors of the host species. However, in the Polyrhachis lama–Diacamma sp. association, the associated species belong to different ant subfamilies. Based on preliminary field surveys, we had presumed that P. lama might have given up its… 

Molecular evidence of chemical disguise by the socially parasitic spiny ant Polyrhachis lamellidens (Hymenoptera: Formicidae) when invading a host colony

The mechanism of chemical disguise in a new queen of a temporary socially parasitic spiny ant (Polyrhachis lamellidens) is investigated by measuring its cuticular hydrocarbon (CHC) profile, performing a tracing assay with labelled substances, and analysing gene expression levels, which suggest that P. lameLLidens directly obtains host CHCs through rubbing behaviour, and thesehost CHCs enables P. excuses to remain disguised during colony invasion.

Polyrhachis lama, a parasitic ant with an exceptional mode of social integration

It is demonstrated that the parasite brood has a high degree of spatial integration, although it remains functionally separated regarding nutritive brood care, which suggests an active mechanism of chemical integration based on the acceptance allomones originating from P. lama workers.

Social parasitism among ants: a review (Hymenoptera: Formicidae)

There is no evidence for the evolution of all types of social parasitism towards inquilinism via multiple pathways as had been formerly suggested, and social parasitic ants are considered interesting with respect to understanding conflict and cooperation among ants.

A chemical level in the coevolutionary arms race between an ant social parasite and its hosts

It is shown that in behavioural aggression trials, host colonies could indeed discriminate between invading slaves, which commonly accompany slavemakers on raids, and free‐living conspecifics, presumably to reduce the costs of defence.

Chemical mimicry or crypsis—the evolutionary game played by parasitic ants invading other colonies

A mathematical model is developed to describe the conditions under which each of these strategies evolves, assuming that the parasites and hosts are ants with their own colonies, and defines parasites’ fitness with respect to chemical profiles.

Nest construction in the arboreal ant Polyrhachis tubifex Karavaiev, 1926

The ant genus Polyrhachis is considered to be one of the 'giant' ant genera and with over 500 described species divided into 12 subgenera it continues to attract significant interest from taxonomists and behavioural ecologists alike.

Propagule Pressure and Climate Contribute to the Displacement of Linepithema humile by Pachycondyla chinensis

This work uses a combination of seasonal surveys and experimental approaches to test the relative importance of behavioral and abiotic factors in determining the local co-occurrence of two invasive ant species, the established Argentine ant and the newly invasive Asian needle ant.

The Higher Classification of the Ant Subfamily Ponerinae (Hymenoptera: Formicidae), with a Review of Ponerine Ecology and Behavior.

The tribal and generic classification of the diverse ant subfamily Ponerinae (Hymenoptera: Formicidae) is revised to reflect recent molecular phylogenetic information and a reappraisal of ponerine

Modèle comportemental de la dynamique de construction de la structure épigée du nid chez la fourmi Lasius niger : approches expérimentales et théoriques

La structure epigee du nid de la fourmi Lasius niger, prise comme un exemple typique des structures alveolaires construites par les insectes sociaux, resulte de l'accumulation d'actes individuels de



Social parasitism involving ants of different subfamilies: Polyrhachis lama (Formicinae) an obligatory inquiline of Diacamma sp. (Ponerinae) in Java

An evolutionary origin of this kind of parasitism from mimetic relations between Polyrhachis lama and the pugnacious Diacamma species is suggested.

Polyrhachis loweryi (Formicinae): A guest ant parasitizing Rhytidoponera sp. (Ponerinae) in Queensland, Australia

It is concluded that P. loweryi is best described as a guest ant of Rhytidoponera sp.. the species seems to be less well integrated into the societies of its Rhytids, and may emigrate with a few eggs or larvae in order to rear them in neighbouring host nests.

Nesting and food resources of syntopic species of the ant genus Polyrhachis (Hymenoptera, Formicidae) in West-Malaysia

Investigation of the nesting and nutrition habits of 10 syntopic species of Polyrhachis in West-Malaysia revealed four different nest types, and nesting habits as well as nutrition habits seem to be key factors allowing the coexistence of so many different species.

Recruitment Behavior in the Ant Genus Polyrhachis (Hymenoptera, Formicidae)

We present a detailed behavioral analysis of the signals involved in recruitment of 11 syntopic Polyrhachis species from West Malaysia. We found a considerable variety of recruitment techniques,

Interspecific Trail Following and Commensalism Between the Ponerine Ant Gnamptogenys menadensis and the Formicine Ant Polyrhachis rufipes

The first report of commensalism between a ponerine and a formicine ant is reported, and the workers of Polyrhachis rufipes show a typical aggressive antennal boxing to which Gnamptogenys reacts with a submissive behavior.
