This study provides floral visitors and pollinators Syagrus orinocensis, Syagrus sancona and Syagrus smithii palms final data, which have an allopatric distribution and they are endemic of Colombia. This study was divided into two chapters, the first chapter which was evaluate the space-temporal variations of floral visitors of S. sancona and the second where S. smithii biological aspects were evaluated and and comparison of floral visitors of three species of Syagrus which have a present in Colombia was made. All insects and other arthropods were identified and quantified which they were
found associated inflorescences; in the first chapter was evaluate the richness, abundances and the relationship of the floral visitors related to male and female phase of inflorescences during 5 floral periods and 6 populations, whereas in the second chapter was evaluate specificity of the floral visitors of the three species of Syagrus and some aspects about ecology of pollination of S. smithii. Diversity indices, richness, importance on pollination were determinated; the level of specificity, behavior,
resource exploitation and relationship of each visitor over inflorescences in male and female phase were evaluated. Within founding results we discover a high specificity and specialization of flower visitors with the palms of the genus Syagrus. For S. sancona variation of 70% of floral visitors to spatial and temporal scale was not presented showing a high specialization with palm. Otherwise, S. smithii shares only about 50% of the species of insect visitors with S. orinocensis and S. sancona, showing a high degree of specialization and specificity by their floral visitors. In conclusion, the
palms of the genus Syagrus have interaction mechanisms highly specialized and specificity with their floral visitors who take advantage of the rewards that inflorescences provide.
