Changes in weight of pharyngeal gland and haemolymph titres of juvenile hormone, protein and vitellogenin in worker honey bees






Journal of Insect Physiology 28(1): 61-68

Changes in weight of pharyngeal gland and haemolymph titres of juvenile hormone, protein and vitellogenin in worker honey bees

Physiological changes were studied in bees of different ages at different seasons. The level of juvenile hormone (JH) increased continuously in ageing summer bees, but was always low in bees at the beginning of winter. At the end of winter it rose to a level similar to that in summer bees 24-40 days old. In bees induced experimentally to live longer than normal in summer, the JH level did not rise.
