Beta-ionone attracts Euglossa mandibularis (Hymenoptera, Apidae) males in western Parana forests

Males of Euglossa mandibularis were consistently captured in scent traps baited with beta-ionone in areas of Mixed Ombrophylous Forests or transition between this latter physiognomy and Montane Semideciduous Forest at Parque Nacional do Iguacu, Parana state, Brazil. Geographic records for the species and sampling effort (including or not beta-ionone among the offered compounds) along Atlantic Forest biome are presented and discussed. We also discuss seasonal and geographic variation in collection of scents by orchid bees. (C) 2015 Published by Elsevier Editora Ltda.
