title: Exocrine gland secretions of virgin queens of five bumblebee species (Hymenoptera: Apidae, Bombini).
abstract: Secretions of three different glands (mandibular gland, labial gland, and Dufour's gland) of virgin queens of five bumblebee species (Bombus lucorum, B. lapidarius, B. hypnorum, B. pascuorum, and B. terrestris) were analysed. Around 200 compounds were identified in the secretions. The compositions of the secretions of labial and mandibular glands were species-specific. Dufour's gland of all species produced mainly hydrocarbons, both saturated and unsaturated, the proportions of which differed quantitatively between the species studied.
