Beekeeping
The queen is the only sexually mature female in the hive and all of the female worker bees and male drones are her offspring. The queen may live for up to three years or more and may be capable of laying half a million eggs or more in her lifetime. At the peak of the breeding season, late spring to summer, a good queen may be capable of laying 3,000 eggs in one day, more than her own body weight. This would be exceptional however; a prolific queen might peak at 2,000 eggs a day, but a more average queen might lay just 1,500 eggs per day. The queen is raised from a normal worker egg, but is fed a larger amount of royal jelly than a normal worker bee, resulting in a radically different growth and metamorphosis. The queen influences the colony by the production and dissemination of a variety of pheromones or "queen substances". One of these chemicals suppresses the development of ovaries in all the female worker bees in the hive and prevents them from laying eggs.
Varroa jacobsoni
The lifecycle of "V. jacobsoni" in "A. cerana" begins with a mature mated female entering a larval cell of a honey bee. Once the cell is capped, the adult female mite hides for five days inside the larval food near the bottom of the cell. After about five hours, the mite is released from the food, where it then begins feeding on the host's haemolymph. After 60 hours, the adult female mite lays its first egg on the wall of the cell. Unfertilised mite eggs produce male offspring, that are able to mate with the female offspring. The adult mated female then emerges from the cell with the emerging bee. Once mites are released to the environment, they are transferred to other bees through close contact. The adult female mites then feed through the intersegmental membrane on honeybee haemolymph. The cycle is then completed.
