The fully developed eggs pass out through the oviduct into the vagina, where they are fertilized by sperm cells that were placed in a sac called the seminal receptacle by a drone during the nup- tial flight of the queen. The drones form the sperm cells in two testes, but the sperms are stored in seminal vesicles from which, during mat- ing, they are transferred to the seminal receptacles of the queen. The queen lays fertilized eggs in honeycomb cells of the worker and unfertilized eggs in the larger drone cells. Just how she controls the actual fertilization cocoon. .W-^ of the egg is not known. According to Nolan,^ the queen produces an average of about 900 eggs a day during the season, but may lay as many as 2000 a day during the period of greatest honey making. The queen places the eggs in the cells by means of an ovipositor, which in the workers is modified into a sting. The latter structure is made up of two darts, closely applied to each other so as to form a tube through which poison from a poison sac flows when the darts are forced out of their sheath as the bee stings. Two different poisons are produced, one of which is formic acid, the other an alkahne substance. Worker bees usually die after stinging, as the sting with its attached parts, along with some of the intestine, is left in the wound. The queen, which also has a sting, uses it only in combat with other queens and does not lose her life in its use. The life history of the bee is rather brief. Three days after fertiliza- tion the egg hatches into a larva which lies in the cell surrounded by a plentiful supply of "bee milk," a mixture of digested honey, pollen, and saliva. After three days of feeding by the young "nurse" bees, the larvae are given more and more undigested food. Drones are. <^©er2 cell Cells of hive of honey bee.
