Die inquiline Ameise Myrmica karavajevi benutzt sowohl chemische als auch akustische (Vibrations-) Signale um sich in die Wirtskolonie zu integrieren.

Abstract
Social parasitism represents a particular type of agonistic interaction in which a parasite exploits an entire society instead of a single organism. One fascinating form of social parasitism in ants is the “inquilinism”, in which a typically worker-less parasitic queen coexists with the resident queen in the host colony and produces sexual offspring. To bypass the recognition system of host colonies, inquilines have evolved a repertoire of deceiving strategies. We tested the level of integration of the inquiline Myrmica karavajevi within the host colonies of M. scabrinodis and we investigated the mechanisms of chemical and vibroacoustic deception used by the parasite. M. karavajevi is integrated into the ant colony to such an extent that, in rescue experiments, the parasite pupae were saved prior to the host’s brood. M. karavajevi gynes perfectly imitated the cuticular hydrocarbon profiles of M. scabrinodis queens and the parasite vibroacoustic signals resembled those emitted by the host queens eliciting the same levels of attention in the host workers during playback experiments. Our results suggest that M. karavajevi has evolved ultimate deception strategies to reach the highest social status in the colony hierarchy, encouraging the use of a combined molecular and behavioural approach when studying host–parasite interactions.
Keywords: host–parasite interactions; social parasitism; cuticular hydrocarbons; stridulation; Myrmica ants

Die sozialparasitische, arbeiterinlose Myrmica karavajevi wurde in einer Population von Myrmica scabrinodis in Krakau (Polen) gesammelt. Ihre Gynen-Puppen sind nur so groß wie die Arbeiterinnen-Puppen der Wirtsart, doch sind sie aufgrund der Flügelscheiden von diesen zu unterscheiden. Daran konnte man man parasitierte Völker erkennen. Stridulations- und chemische Signale der Wirtsart werden von den Parasiten-Gynen imitiert.

Electron Scan Microscope images of the whole pars stridens and ridges of (a,d) [i]Myrmica karavajevi queens and (b,e) M. scabrinodis queens and (c,f) workers.[/i]

Zur Erinnerung: Die meisten Myrmicinen haben ein Stridulationsorgan zwischen Postpetiolus und dem ersten Gastertergit. Bei Auf- und Abbewegungen der Gaster streicht ein Plectrum (Schrillkante) am Hinterrand des Postpetiolus über ein Rippenfeld (pars stridens) ganz vorne auf dem ersten Gastersegment, wobei ein zirpendes Geräusch entsteht. Die Ameisen selbst nehmen das als Substratschall wahr, da sie ja keine eigenen Hörorgane haben. (https://ameisenwiki.de/index.php/Stridulation und viewtopic.php?f=11&t=1529&p=16670)

Die Art M. karavajevi war früher zeitweilig in eine eigene Gattung Sifolinia gestellt. Synonyme sind laut AntWiki: Myrmica faniensis Boven, 1970; Sifolinia pechi Samsinak, 1957, Sifolinia winterae Kutter, 1973.
Nach Seifert (2018) steht sie jedoch zusammen mit drei weiteren westpaläarktischen Parasitenarten in der Gattung Symbiomyrma Arnoldi 1930.
(Leider wurde über die taxonomische Zugehörigkeit dieser Inquilinen von Myrmica spp. mehr publiziert als über ihre weitgehend unbekannte Lebensweise: Alle Arten werden nur selten gefunden!)
