| Sumario: | [EN]The objective of this research was to describe the biological interaction between Salvia bogotensis (Lamiaceae) and the flower flies (Diptera:Syrphidae) in an urban setting, the Jardín Botánico “José Celestino Mutis” (Bogotá DC). After verifying the existence of the entomofilia syndrome were studied namely: floral morphology, taxonomic composition, richness and abundance of syrphid species identified as flower visitors and the cephalic and oral morphometry. S. bogotensis presents entomophily syndrome with absence of selfing. Syrphid community associated with S.bogotensis includes nine species, grouped into five genus. The species are Allograpta neotropica Curran, 1936, Allograpta exotica Wiedermann, 1830, Allograpta annulipes Macquart, 1850, Allograpta aenea Hull, 1937, Lejops mexicana Macquart, 1842, Platycheirus ecuadoriensis Fluke, 1945, Platycheirus fenestrata Macquart, 1842, Syrphus shoree Fluke, 1950 y Toxomerus sp. 1. The species of flower flies (Syrphidae), as a whole, showed behavioral and morphological characteristics associated with low-efficiency pollinators, with a low rate of visits, inability for activation of levers staminal and minimal contact insect body with the anthers and stigma of the flower. Additionally, the flies showed a very low load of pollen grains of S. bogotensis in the body, with high investment of time in cleaning its body (grooming). Flowers visited by these insects were not involved in the formation of fruit. All this leads to the conclusion that these insects do not participate effectively in the pollination of S. bogotensis. Other insect visitors who might be responsible of the pollination were species of the families Apidae, Halictidae and Megachilidae. In particular, hoverflies are benefit by eating pollen of S. bogotensis, however, it does not interfere with growth and plant development, which can be inferred that the relationship between hoverflies and S. bogotensis is of type commensalism. |
