About this book
Workers, drones, and queens have various glands that produce pheromones. These pheromones include the queen mandibular pheromone that enables a colony to detect the presence of their queen, brood pheromones that signal the type of care required by the immature bees in the colony, and Nasanov pheromone Figure 10 that communicates the location of the colony to workers who may have been displaced in a colony disturbance.
Figure Worker European honey bee, Apis mellifera Linnaeus, exposing the Nasanov gland at the tip of the abdomen and fanning her wings to release Nasanov pheromone when the colony was disturbed by removing the lid. One of the most notable honey bee behaviors is stinging. Stinging is a defensive behavior worker bees use to protect the colony. When a colony intruder is detected, guard bees release an alarm pheromone that elicits a defensive response by the colony.
Moreover, when a honey bee stings, it releases alarm pheromone to attract more bees to sting the location that was stung. All worker honey bees die after stinging, and European honey bees rarely sting without provocation. Due to their highly social life history, honey bee colonies can be considered superorganisms. This means the entire colony, rather than the bees individually, is viewed as the biological unit. With that in mind, honey bees reproduce not by producing more individual bees, but rather by producing more colonies.
The reproductive process of creating a new colony is called swarming. European honey bees typically swarm in the spring and early summer when pollen and nectar resources are plentiful. To initiate the swarming process, 10 to 20 daughter queens are produced by the colony. A reproductive swarm of European honey bees, Apis mellifera Linnaeus, coalesced on a tree branch while scout workers search for a place to establish the new colony.
The daughter queens in the original colony then emerge as adults and fight until a single queen remains alive, unless one queen emerges earlier than her sisters, in which case she will hunt for and kill her unborn siblings. After a short time of further maturation, the remaining daughter queen leaves the colony to mate with about 15 drones. The queen then stores the collected sperm in her spermatheca for the remainder of her life.

Once successfully mated, the daughter queen begins laying eggs, thus completing both halves of the swarming process. European honey bees are adapted to temperate climates, where there is only a short season with generous amounts of pollen and nectar available. For this reason, they typically swarm only once a year.
This behavior of resource hording is what makes European honey bees excellent honey producers. Nectar is collected from flowers and transformed into honey though enzymatic processes and dehydration within the colony. At this time, the honey is capped over in the wax comb where it can stay fresh almost indefinitely, depending on the original nectar source. Beekeepers and honey hunters may then collect this honey comb for human consumption.

In fact, pollination by honey bees contributes significantly to global food production. In addition to providing pollination services, honey bees also produce other products that people use including honey, pollen, wax, royal jelly, and propolis. Honey bee management is popular worldwide and varies greatly in style and scale.
Commercial beekeepers may maintain 2, or more colonies, whereas a hobbyist beekeeper may have as few as one. The equipment used to house honey bee colonies is also very diverse.watch

Some of the more popular equipment styles include skeps, top bar, log gum, and Langstroth hives, with the Langstroth hive being the most widely used in the United States Fig. An apiary of managed European honey bee, Apis mellifera Linnaeus, colonies in Langstroth hives. Honey bee pathogens and pests have been spread around the world with the movement of European honey bees.
In the United States, European honey bees are susceptible to a wide range of viral, fungal, and bacterial infections including, but not limited to, Deformed Wing Virus, chalk brood, Nosema , European foulbrood, and American foulbrood. European honey bees also host natural pests, such as tracheal mites and wax moths , and introduced ones, such as small hive beetles a honey bee pest from Africa and Varroa mites a honey bee parasite from Asia.
Beekeepers use integrated pest management strategies to maintain the impacts of the numerous pest- and pathogen-related problems below an acceptable threshold. Some of these control methods include selecting appropriate apiary locations, supplemental feeding, trapping pests in colonies, replacing queens, preventative treatments, and chemical control.

Honey bee colonies themselves also can be considered a pest when a feral swarm establishes a new colony in an undesirable location, such as the wall of a house, a mail box, or some other location where they will come into frequent contact with humans Figure In this case, a trained professional or beekeeper should be contacted to remove the nuisance colony.
