Resumo
Sequential flowering strategy consists in blooming of different species consecutively through the year. This strategy is crucial to the maintenance of pollinators, because ensure food for them along the year. The purpose of this study was investigate beeflower interactions of a sequentially flowering species in coastal environment. The study was conducted at Paulo Cesar Vinha State Park, Guarapari, ES, from October 24, 2012 to November 13, 2013. Data of bees were recorded through direct observations. Collections were made directly on flower. Observations and collections were accomplished in seven plant species (168 hours). Plants were visited by bees and bloomed sequentially. Results showed 594 visits of bees (Apidae and Halictidae). They were identified in 15 native morpho-species and one exotic. Apidae presented 87,3% of the visits and Frieseomelitta sp1 was the most frequently eusocial morphospecies founded. Pollen, nectar and resin were the floral resources collected by visiting bees. Trigona sp1 was the only morphospecies that collected latex and nectar. Visits occurred predominantly in the morning. Rainfall during the flowering period was correlated with visits number. From May to September 2013 showed a strong reduction in the bee visits frequency. After this period, Augochloropsis sp1, Frieseomelitta sp1, Trigona sp1 and Tetragonisca sp1 returned to visit the flowers. All native bees are first record for PEPCV. Bees are potential pollinators of the studied plant species due to their visitation frequency and their contact with the reproductive parts (male and female) of their visited flowers plants.
