Identical Isoprenoid Esters in the Dufour's Gland Secretions of North American and European Andrena Bees (Hymenoptera: Andrenidae)

Volatile secretions from the Dufour's gland in 8 species of Andrena bees occurring in central North America have been analyzed by combined capillary gas chromatography and mass spectrometry. In one species, Andrena mandibularis, geranyl octanoate was found to be the main component, whereas in t...

Description
Summary:Volatile secretions from the Dufour's gland in 8 species of Andrena bees occurring in central North America have been analyzed by combined capillary gas chromatography and mass spectrometry. In one species, Andrena mandibularis, geranyl octanoate was found to be the main component, whereas in the other 7 species all-trans-farnesyl hexanoate dominated the secretion. The chemical analyses, 14 in all, were done on individual preparations. In addition to the main compounds, some other isoprenoids and some straight chain, saturated hydrocarbons were present in smaller amounts. The analytical results agree well with earlier analyses of 19 species of European Andrena. The dispersal of the genus Andrena between Europe and North America is discussed.
