Résumé : The response of mature female Mediterranean Fruit Fly (Ceratilis capitata (Wiedemann)) to various combinations of visual and olfactory stimuli was studied in field cages. Cohorts of laboratory reared mature females of known age were relased in the cage in choice experiments. Sources of olfactory stimuli were proposed to the flies inside small spheres (4,5 cm diameter) painted with an attractive (red, fluorescent yellow) or a non-attractive (blue) colour. Olfactory stimuli were of two types : food stimuli (protein hydrolysate or Torula yeast) or kairomone-type stimuli (pulp of host fruits). Flies on the different spheres were counted at regular time intervals. In red spheres, orange pulp odour was significantly more attractive for the females than no odour or Torula yeast odour. When proposed in spheres of different colours, orange pulp odour was more attractive in red than in fluorescent yellow or blue spheres. On the contrary, Torula yeast odour appeared more attractive in fluorescent yellow spheres than in red or blue spheres. In red spheres, no significant difference was observed between the odour of tangelo, tangerine and pomelo or tangelo, orange and tangor, respectively. The quantity of pulp used as a source of odour (15, 30 or 45 g) didn't influence markedly female response. Coffee fruit odour was also shown to be less attractive than orange odour in red spheres.
