Mitochondrial DNA diversity of orchid bee Euglossa fimbriata (Hymenoptera: Apidae) populations assessed by PCR-RFLP.

Euglossa fimbriata is a euglossine species widely distributed in Brazil and occurring primarily in Atlantic Forest remnants. In this study, the genetic mitochondrial structure of E. fimbriata from six Atlantic Forest fragments was studied by RFLP analysis of three PCR-amplified mtDNA gene segments (16S, COI-COII, and cyt b).

Eufriesea violacea (Blanchard) (Hymenoptera: Apidae): an orchid bee apparently sensitive to size reduction in forest patches.

Eufriesea violacea (Blanchard) is a very seasonal euglossine species, more frequently found in the southern and southeastern regions of Brazil. A number of studies have revealed large variations in the abundance of males of this species present in Atlantic Forest remnants throughout both regions. In this paper, we report variations in the abundance of E.
