Abstract:
The sterols of the organs (hypopharyngeal and mandibular glands and honey stomachs) involved in worker and queen honey bee brood food production, royal jelly and intact nurse bees were analyzed to obtain information on the selective transfer of specific sterols from one generation to the next. No appreciable increase in the percentage of 24-methylenecholesterol, relative to the total sterols isolated from intact honey bee (Apis mellifera L.), prepupae or adults, was found in the hypopharyngeal or mandibular glands or the honey stomachs from nurse bees reared in colonies fed a chemically-defined diet supplemented with 24-methylenecholesterol. The sterols of these organs contained higher levels of cholesterol than did the sterols of whole body extracts. The other major sterols, sitosterol and isofucosterol, occurred at relative concentrations comparable to whole body extracts. Also, there were higher levels of cholesterol in the sterols from glandular tissues of nurse bees maintained on pollen and sucrose solution than in sterols isolated from intact insects. In a separate study, royal jelly collected over a 6-day period had much higher relative percentages of 24-methylenecholesterol and lower levels of sitosterol and isofucosterol than did the pollen fed to these colonies. The sterols of nurse bees in the latter study had an intermediate concentration of 24-methylenecholesterol. The significance of these findings relative to the unique selective transfer of specific sterols from the diet or from endogenous sterol pools of the nurse bees from generation to generation in the honey bee is discussed. © 1986.

Sterols of organs involved in brood food production and of royal jelly in honey bees
The sterols of the organs (hypopharyngeal and mandibular glands and honey stomachs) involved in worker and queen honey bee brood food production, royal jelly and intact nurse bees were analyzed to obtain information on the selective transfer of specific sterols from one generation to the next. No appreciable increase in the percentage of 24-methylenecholesterol, relative to the total sterols isolated from intact honey bee (Apis mellifera L.), prepupae or adults, was found in the hypopharyngeal or mandibular glands or the honey stomachs from nurse bees reared in colonies fed a chemically-defined diet supplemented with 24-methylenecholesterol.
