Este trabalho teve como objetivo estudar a polinizacao de Canavalia rosea (Sw.) DC. (Leguminosae-Papilionoideae) por abelhas na vegetacao de restinga da Area de Protecao Ambiental de Grumari, localizada na zona oeste do municipio do Rio de Janeiro. O estudo foi desenvolvido entre os meses de junho de 2008 a junho de 2009, realizando-se observacoes sobre morfologia, cor e odor das flores da especie. Foi registrado o numero de flores abertas por dia em cada individuo, bem como as etapas de abertura, determinando-se o periodo da antese. A ocorrencia de visitantes florais foi registrada observando-se o horario de visita, a adaptabilidade para polinizacao, a facilidade de acesso a recompensa e o comportamento intra-floral desempenhado. C. rosea ocorre nas comunidades psamofila e pos-praia da restinga da APA de Grumari. Apresenta caracteristicas tipicas da melitofilia (polinizacao por abelhas) e as flores sao polinizadas por Xylocopa frontalis Oliver. Sao ainda visitas por Tetragonisca angustula Latreille, Trigona spinipes Fabricius e Apis mellifera Linnaeus, que recolhem polen sem polinizar as flores. X. frontalis mostrou ser o unico polinizador efetivo de C. rosea na restinga de Grumari, tornando a planta diretamente dependente desta especie para producao de frutos e sementes nesta localidade. Mellitophily in Canavalia rosea (Sw.) DC. (Leguminosae-Papilionoideae) Abstract. This work aimed to study the floral biology and the pollination’s ecology of Canavalia rosea (Sw.) DC. (Leguminosae-Papilionoideae) by bees in the sandbank vegetation of the Grumari Environmental Protection Area (EPA) , located in the western zone of Rio de Janeiro’s city. The study was developed between the months of June of 2008 to June of 2009. Sampling on morphology, color and odor of the flowers of the species were made. The number of open flowers per day in each individual was recorded, as well as the opening steps, determining the period of anthesis. The occurrence of floral visitors was recorded through the observation of the visit’s time, of the adaptability for pollination, of the ease of access to the reward and of the intra-floral behavior played. C. rosea occurs in psamophily communities and in post-beach sandbank of Grumari’s EPA. It presents typical characteristics of mellitophily (pollination by bees) and the flowers are pollinated by Xylocopa frontalis Oliver. It also receives visits from Tetragonisca angustula Latreille, Trigona spinipes Fabricius and Apis mellifera Linnaeus, which collects pollen without pollinating the flowers. X. frontalis proved to be the only effective pollinator of C. rosea in the Grumari sandbank, making the plant directly dependent on this species for fruit and seed’s production in this location.
