Pollination by deceit in a mass-flowering tropical tree Plumeria rubra L.(Apocynaceae)

Tipo de material: TextoTextoSeries ; Biotropica, 16(4), p.269-275., 1984Trabajos contenidos:

Tema(s): Recursos en línea: Resumen: Flowers of Plumeria rubra, a mass-flowering tropical tree, share many traits with hawkmoth-pollinated flowers, and Plumeria pollen was recovered from the tongues of 17 hawkmoth species in Costa Rica. Rates of visitation and fruit set were exceptionally low compared with other hawkmoth flowers sympatric with Plumeria, apparently because Plumeria flowers produce no nectar reward. Hawkmoths in a flight cage quickly learned to avoid nectarless Plumeria flowers, but readily fed from these flowers after artificial nectar was added. Although no specific model for Plumeria was found in Costa Rica, the presentation of generalized odor and visual cues that mimic typical hawkmoth flowers may facilitate deceitful pollination of Plumeria.
