Développement ovarien et statut social chez une fourmi primitive neoponera obscuricornis emery (hym. Formicidae, ponerinae)
Ovarian development and social status in a primitive ant, Neoponera obscuricornis Emery (Hym. Formicidae, Ponerinae). A detailed investigation of polyethism was carried out on a colony of Neoponera (=Pachycondyla sensu Brown, 1973) obscuricornis, involving behavioral observations on its inhabitants, and subsequent dissection of each. Ovarian development in each ant was closely related to its social status. Ovaries are well developed among nurses and totally degenerate in foragers. This is the case in both gynes and workers, and ovarian polymorphism between the two castes is only weakly marked. The evolutionary implications of the observed relationships between nursing behaviour and reproductive ability are discussed
