Absolute Configuration of Chiral Terpenes in Marking Pheromones of Bumblebees and Cuckoo Bumblebees

The absolute configurations of citronellol, 2,3-dihydrofarnesol, and 2,3-dihydrofarnesal in male marking pheromones of bumblebees were determined by gas chromatography on a column coated with 60% heptakis(2,3-di-O-acetyl-6-O-TBDMS)-beta-cycl...

A scent shield to survive: identification of the repellent compounds secreted by the male offspring of the cuckoo bumblebee Bombus vestalis

In bumblebees, previous investigations indicated that male offspring of Bombus vestalis, the social parasite of Bombus terrestris, may use allomones to evade host worker attacks. Here we performed electrophysiological studies and behavioural...
