Worker Reproduction in the Highly Polygynous Ant Crematogaster pygmaea Forel, 1904 (Hymenoptera: Formicidae)
In most ant species, workers have retained functional ovaries, allowing them to potentially lay viable unfertilized eggs that develop into males. Mechanisms (ex.: queen and/or worker policing) have nevertheless evolved to control worker reproduction when the queen is present. In many species with a high degree of polygyny, especially in tramp species, complete sterility of workers has evolved, presumably to “trap” them within their “worker phenotype”. Our study showed for the first time that in the highly polygynous and polydomous ant Crematogaster pygmaea, workers retained the full capacity to produce reproductive eggs in queenless colonies, with at least some of them developing in adult males. We provide evidence that worker-produced males are reproductively functional. Although most queenless colonies produced eggs, few larvae developed into pupae and adult males. We conclude that workers strongly police the worker-produced offspring, even in the queen's absence. Probable high relatedness between queens of C. pygmaea colonies and strong genetic proximity between brood and workers could force the workers in their helper, non-reproductive function even if they keep the ability to reproduce. Our observations indicate that the production of adult males and gynes in C. pygmaea is controlled by seasonal factors related to the rainy season.
期刊介绍:
SOCIOBIOLOGY publishes high quality articles that significantly contribute to the knowledge of Entomology, with emphasis on social insects. Articles previously submitted to other journals are not accepted. SOCIOBIOLOGY publishes original research papers and invited review articles on all aspects related to the biology, evolution and systematics of social and pre-social insects (Ants, Termites, Bees and Wasps). The journal is currently expanding its scope to incorporate the publication of articles dealing with other arthropods that exhibit sociality. Articles may cover a range of subjects such as ecology, ethology, morphology, population genetics, physiology, toxicology, reproduction, sociobiology, caste differentiation as well as economic impact and pest management.
