An Entity of Type: anatomical structure, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Metapleural glands (also called metasternal or metathoracic glands) are secretory glands that are unique to ants and basal in the evolutionary history of ants. They are responsible for the production of an antibiotic fluid that then collects in a reservoir on the posterior of the ant's alitrunk. These reservoirs are also referred to as the bulla and vary in size between ant species and also between castes of the same species.

  • Les glàndules metapleurals (també anomenades glàndules metasternals o metathoràciques) són glàndules secretores úniques de les formigues i basals en la història evolutiva de les formigues. Són responsables de la producció d'un líquid antibiòtic que després es recull en un dipòsit a la part posterior de l'alitrunk de la formiga. Aquests embassaments també es coneixen com a bulla i varien en grandària entre espècies de formigues i també entre castes de la mateixa espècie. (ca)
  • Metapleural glands (also called metasternal or metathoracic glands) are secretory glands that are unique to ants and basal in the evolutionary history of ants. They are responsible for the production of an antibiotic fluid that then collects in a reservoir on the posterior of the ant's alitrunk. These reservoirs are also referred to as the bulla and vary in size between ant species and also between castes of the same species. From the bulla, ants can groom the secretion onto the surface of their exoskeleton. This helps to prevent the growth of bacteria and fungal spores on the ants and inside their nest. Though considered an important component in an ant's immunity against parasites, some ant species have lost the gland during their evolution. These losses correlate with ants that have a 'weaving' lifestyle, such as ants in the genus Oecophylla, Camponotus and Polyrhachis. It was originally suggested that because this weaving lifestyle also tended to involve an arboreal lifestyle, the parasite pressure above ground was not as great as for terrestrial ants, resulting in a reduced selective pressure to keep this antibiotic gland. Recent work suggests instead that these ants may just use other antiparasite defences such as increased grooming and venom. Most male ants are not known to have metapleural glands. It is believed that they benefit from the shared secretions of ant workers and do not need any themselves. Additionally, slave-making ants do not have metapleural glands, though the slave species they use do and it is these ants that groom the slavemakers and their brood. (en)
  • La glande métapleurale, aussi appelée glande métasternale ou glande métathoracique, est une glande exocrine unique aux fourmis. Elle est considérée comme une synapomorphie de cette famille, bien qu'elle soit disparue indépendamment au sein de certaines lignées. Sa principale fonction serait, la sécrétion lors des séances d'auto-toilettage de composés aux activités antimicrobiennes et antifongiques (acide phénylacétique, myrmicine) servant de défenses chimiques contre les pathogènes, mais d'autres fonctions ont été documentées chez certaines espèces. Sa taille varie entre les espèces et entre les castes. (fr)
  • Метаплевральная железа (Metapleural gland, metasternal/metathoracic gland) — специфическая железа внешней секреции, характерная только для муравьёв, выполняющая в основном защитную антибиотическую роль. Расположена в нижне-боковой части заднегруди. Один из главных признаков семейства Formicidae, так как эта железа обнаружена практически у всех современных видов муравьёв (за редкими исключениями, возникшими вторично). (ru)
