The sterols of prepupal honey bees, Apis mellifera L., from brood reared by workers fed chemically-defined synthetic diets containing cholesterol, campesterol, sitosterol, stigmasterol, 24-methylenecholesterol, or no sterol over a 12-week period were

The esterified and unesterified sterol fractions of bee-gathered mixed pollens were examined, and total sterol composition was determined. Two new sterols of pollens, 14α-methyl-9β,19-cyclo-5α-cholest-24-en-3β-ol (24-dehydropollinastanol) and 14

The fate of radiolabelled campesterol, sitosterol and 24-methylenecholesterol fed in chemically-defined diets to honey bee (Apis mellifera L.) workers was determined. At various intervals, sterols of prepupae, newly emerged adults and queens were ana

SummarySmall colonies were maintained for 10 weeks in outdoor flight cages of various sizes. Both brood rearing and food consumption decreased significantly with cage size, and were significantly correlated. Colonies maintained in the largest cage (3

Pollen collected by bees was sampled during a 3-h period once a week from April to October 1983 and analyzed for vitamin C (L-ascorbic acid and dehydroascorbic acid). The levels were highly variable and ranged from a low of 136 μg/g pollen (April) t

SummaryThe whole lipid fraction of fresh bee-collected pollen was encapsulated in a starch polymer and added to a whey-yeast pollen substitute. Honeybee colonies fed pollen substitute supplemented with 2, 4, 6 or 8% (dry weight) of the lipid reared s

Sterols from pollen collected by foraging honeybees, Apis mellifera L, at seven field sites were compared with the sterols of foraging adults and/or prepupae collected from colonies at each site. Invariably, the composition of prepupal sterols was co
