Les « jardins de fourmis », une association plantes-fourmis originale
This work presents here in detail the characteristics of the ant gardens initiated in French Guiana by the parabiotic associations Crematogaster limata parabiotica/Camponotusfemoratus and by the ants Pachycondyla goeldii and Odontomachus mayi. Expand
Adaptation d'Oecophylla longinoda [Formicidae-Formicinae] aux variations spatio-temporelles de la densité de proies
The predatory activity of 12 societies of Oecophylla longinoda Latreille was observed for 124 hours during which 2,482 prey items were captured. Expand
Mise En Evidence D'Une Forme D'Apprentissage Dans Le Comportement De Capture Des Proies Chez Pachycondyla (=Neoponera) Villosa (Formicidae, Ponerinae)
[Confrontees aux soldats d'un termite Rhinotermitidae, les ouvrieres de la fourmi predatrice Pachycondyla villosa adoptent une posture de "prudence" grâce a laquelle elles evitent le contact de leursExpand
Etude eco-ethologique de la prédation chez les fourmis du genreSmithistruma (Formicidae-Myrmicinae-Dacetini) II. Attraction des proies principales (Collemboles)
A study of predation in Smithistruma truncatidens and S. emarginata produces a variety of arguments supporting the hypothesis that the foraging workers attract Entomobryan Collembola, which could be due to an allomone. Expand
Etude éco-éthologique de la prédation chez les fourmis du genreSmithistruma (Formicidae, Myrmicinae, Dacetini) III. La capture des proies chezS. Emarginata
Smithistruma are armed with short mandibles, but the size of their principal prey (Collembola) is almost the same as those of other Dacetines armed with long mandibles which permits the utilization of alternative kinds of preys. Expand
La prédation chezOdontomachus troglodytes Santschi (Formicidae-Ponerinae)
Four types of preys were presented to workers of Odontomachus troglodytes and the most complete sequence includes the following phases: detection, localization, approach, antennal palpation, attack, lifting, stinging and transport. Expand

  • 1 June 1990
The influence of the original environmental influence on individuals in the choice between two types of tubes is demonstrated, due to an imprinting during larval life, and strenghened at the beginning of imago life. Expand
Etude Eco-Ethologique de la Predation Chez les Fourmis du Genre Smithistruma (Formicidae-Myrmicinae-Tribu Des Dacetini)—I. Effets Du Milieu Sur le Choix Des Proies Chez Smithistruma Truncatidens Brown
The variations of moisture in the leaf litter of Eucalyptus tally with the fluctuations in the populations of microarthropods of the litter, and shows that the capture of entomobryomorphs is-the highest, whatever the season. Expand
Trajets d'approvisionnement a partir d'un nid central chez la fourmiSerrastruma lujae (Formicidae: Myrmicinae)
The movements of S. lujae worker ants were analysed under experimental conditions approximating those of the African rain season (humidity at saturation point), using a correlated random walk model developed by one of the authors. Expand
