title: Age-dependent changes in the chemistry of exocrine glands of Bombus terrestris queens.
abstract: Extracts of three different glands (mandibular, labial, and Dufour's) of virgin Bombus terrestris queens at ten different ages (1-8, 12, and 18 days) were analyzed for chemical composition. One hundred and twenty-seven compounds were identified in the extracts. The mandibular and labial glands contained previously reported electroantennogram-active compounds (3-hydroxydecanoic acid, fatty acids of different chain lengths, their esters, and heptacosene). These compounds reached a maximum concentration in 3- to 7-d-old queens. Geranylcitronellol was found in both labial and Dufour's glands. Its amount was inversely correlated to age of queens.
