Eight bee species were observed. The wild bee Eucera numida Lepeletier and the honey bee Apis mellifera L. were the most abundant pollinators. Eucera numida seems the most effective pollinator. Their visits are all able to fertilize the fl owers.

The fl oral visits of Eucera numida are also faster (m = 10 visits per minute) and the bee trips more easily the faba bean fl owers than A. mellifera. The plants that are accessible to pollinators provide more pods per plant, more seeds per pods, and the seeds are heavier and of better shape than the encaged plants. Résumé.
