Diversidade e sazonalidade de abelhas Euglossina Latreille (Hymenoptera: Apidae) em duas áreas de mata estacional semidecidual no domínio do cerrado no Triângulo Mineiro.

Abstract

The aim of this study was evaluate ecologic aspects related to euglossine bees in two areas of Semidecidual Seasonal Forest in the municipality of Uberlândia-MG, as well as provide new information about biogeographic distribution pattern of group. The data were collected from July 2008 to June 2009. Were verified the patterns of richness, diversity, community structure, abundance and seasonality of these bees in the studied areas, beyond the preference for aromatic baits. The sampled data were also related with other studies realized in different phytophysiognomies of Cerrado in Triângulo Mineiro, besides data of studies carried out in other areas of Semidecidual Seasonal Forest of different Brazilian regions. A total of 249 euglossine bee males, belonging to three genera and eleven species were sampled, from which Euglossa amazonica represents an additional record of an amazonian species in Cerrado domain. The more efficient bait as for abundance as richness of species was eucalyptol, however some species were not attracted to this compound. The number of males sampled was higher from September 2008 to February 2009. The similarity analysis showed that the similarity Euglossina fauna among areas is related with the phytophysiognomic similarity and that occurs a tendency that semidecidual forest areas geographically closer show more similar euglossine communities.
