Worker Sterility and Queen Signaling
Honeybee Workers are infertile females and possibility of their reproduction is extremely limited. Their fertility is controlled by queen signals. The Queen honeybee informs workers of her presence by pheromones that queens secrete from their mandibular glands. These signals are acquired by workers in close vicinity of the queen and then spread to other works in the colony mainly by body contacts. In presence of queen pheromone signals, the vast majority of workers refrain from activating their ovaries. In the absence of queen bee at least 5% of the worker bees activate their ovaries and start laying eggs, this leads to multiple eggs in one cell. When this occurs, other workers will attempt to remove the eggs, a phenomenon known as worker policing.

Famous quotes containing the words worker and/or queen:
“Photography suits the temper of this age—of active bodies and minds. It is a perfect medium for one whose mind is teeming with ideas, imagery, for a prolific worker who would be slowed down by painting or sculpting, for one who sees quickly and acts decisively, accurately.”
—Edward Weston (1886–1958)
“If it were worth while to argue a paradox, one might maintain that nature regards the female as the essential, the male as the superfluity of her world. Perhaps the best starting-point for study of the Virgin would be a practical acquaintance with bees, and especially with queen bees.”
—Henry Brooks Adams (1838–1918)
