Pollinitation ecology in the Tribe Delphineae (Ranunculaceae) in W mediterranean area: Floral visitors and pollinator behaviour

摘要: The pollination ecology of W. Mediterranean species the genera Aconitum, Delphinium and Consolida has been studied, mainly from point view floral visitors potential pollinators. Investigations about foraging behaviour on flower allowed us to differ between legal pollinators, nectar or pollen robbers, predators accidentals. Field observations showed that main pollinators are hymenoptera genus Bombus, principally in high mountain (Aconitum D. montanum), whereas remaining growing lower habitats a wider taxonomic range visitors, including other Hymenoptera, Lepidoptera Diptera, some which acted as plants studied have complex morphology, closely adapted insect-pollination. They produced large amount specialized structures hidden spur (in Consolida) helmet Aconitum). Correlation nectary length insect tongue studied.
