Popis:	Fertile egg-laying queen honey bees, Apis mellifera L., removed from the colonies and isolated on experimental diets of dextrose-levulose syrup, queen candy, egg albumin, pollen, fresh royal jelly, and royal jelly frozen 3–4 months, continued to expel eggs for only 48 hours, and none of the diets stimulated them to resume egglaying. When such queens were isolated and fed 5 days through screenwire by small numbers (15) of 15-day-old nurse bees feeding on the experimental diets, the subsequent autopsy revealed neither eggs in their oviducts nor ovulable-size eggs in their ovaries. However, when queens in screenwire push-in cages on wax blocks were introduced into larger cages containing 300 workers of known age (4 to 6, 9 to 11, or 14 to 16 days old, or equal numbers of each age group) and the attendants were fed 2.5% pollen in dextrose-levulose syrup (and water), the autopsied queens contained eggs after either 2 or 5 days of such treatment. Isolated queens lived significantly longer on diets of dextrose-levulose syrup, queen candy, or egg albumin than on fresh royal jelly, frozen royal jelly (3–4 months old) in dextrose-levulose syrup, or pollen in a carbohydrate mix.
