The cells discharge their secretory products through accompanying duct cells into a reservoir that is formed by the invaginated intersegmental membrane between the 4(th) and 5(th) sternites. The ultrastructural characteristics of the secretory cells are indicative for the production of a non-proteinaceous secretion, which is in line with the trail substance that is used by these wasps during their swarm-founding.251-255engEpiponiniexocrine glandshistologyUltrastructureArtigoWOS:000292344500025Acesso restrito83471317041536870000-0003-0207-1067
