Abstract
Floral visitors are agents that ensure fertilization and reproductive spread or interfere with the degree of survival of the species. The research aimed to identify the floral visitors in native palm trees and their frequencies. The research was conducted in the dense alluvial rain forest from the Environmental Protection Area Combu Island (00° 38’ 29” S e 47° 31’ 54” W) from march to august 2015 where the floral visitors were collected in nine species of palm trees with the aid of plastic bags of 30 liters and network. The insects collected were transported and identified in the Order level, Family, Genus and Species. For the frequency analysis were classified into Very common (> 26 individuals/species), Common (16-25 individuals/species) and Rare (1 to 15 individuals/species). For the diagram ordering of floral visitors by palm trees applied R Program. Five orders, 14 families, 27 genera and 39 species. Coleoptera and Hymenoptera presented greater number of species were recorded. The species were classified in Rara (45%) Very common (40%) and common (15%) and cantarofilia was predominant . Mauritia flexuosa , Maximiliana maripa and Euterpe oleracea obtained the highest number of visitors. It is concluded that the palm inflorescence attracts mainly beetles and hymenopteros as flower visitors which may contribute to the pollination. Keywords : Arecaceae; polinization; conservation units.
