FATTY ACIDS IN THE HEADS OF WORKER HONEYBEES OF VARIOUS AGES
R. BACH AND D. A. SHEARER
The contents of hexanoic, octanoic, 2-octenoic, 10-hydroxydecanoic and 10-hydroxy-2-decenoic acids in heads of worker honeybees of different ages, and in royal jelly, were determined by gas chromatography. The quantiry of total acids produced by the bees varied with age, but acid ratios did not change significantly and matched that of fresh royal jelly. Workers that survived for more than 5 weeks in summer contained greater amounts of C6 and C8 acids than younger bees.
