why does a bee die after it stings

A honey bee that is away from the hive foraging for or will rarely sting, except when stepped on or roughly handled. Honey bees will actively seek out and sting when they perceive the
to be threatened, often being alerted to this by the release of attack (below). Although it is widely believed that a can sting only once, this is a partial misconception: although the is in fact barbed so that it lodges in the victim's, tearing loose from the bee's and leading to its death in minutes, this only happens if the skin of the victim is sufficiently thick, such as a mammal's. Honey bees are the only with a strongly barbed sting, though and some other wasps have small barbs. Bees with barbed stingers can often sting other insects without harming themselves. Queen honeybees and bees of many other species, including bumblebees and many solitary bees, have smoother stingers with smaller barbs, and can sting mammals repeatedly. The sting's injection of into the victim is accompanied by the release of alarm, a process which is accelerated if the bee is fatally injured.

Release of alarm pheromones near a hive may attract other bees to the location, where they will likewise exhibit defensive behaviors until there is no longer a threat, typically because the victim has either fled or been killed. (Note: A bee, seen as a mass of bees flying or clumped together, is generally not hostile; it has deserted its hive and has no comb or young to defend. ) These pheromones do not dissipate or wash off quickly, and if their target enters water, bees will resume their attack as soon as it leaves the water. The alarm pheromone emitted when a bee stings another animal smells like a banana. bees, the males, are larger and do not have stingers. The female bees ( and queens) are the only ones that can sting, and their stinger is a modified. The has a barbed but smoother stinger and can, if need be, sting skin-bearing creatures multiple times, but the queen does not leave the hive under normal conditions.

Her sting is not for defense of the hive; she only uses it for dispatching rival queens, ideally before they can emerge from their cells. Queen breeders who handle multiple queens and have the queen odor on their hands are sometimes stung by a queen. The main component of responsible for pain in is the toxin ; and other biogenic amines may also contribute to pain and itching. In one of the alternative medical uses of products, bee venom has been used to treat and other painful conditions. All currently available evidence supporting this practice is either anecdotal, animal studies, or preliminary evidence, most of which has poor methodology. While a preliminary, in-vitro proof of concept has demonstrated that isolated melittin may attenuate the infectivity of two specific strains, apitherapy is not currently accepted as a viable medical treatment for any condition or disease; the risk of allergic reaction and outweighs any benefits.

According to the, there is no scientific evidence that apitherapy or bee venom therapy can treat or change the course of cancer or any other disease. have shown that apitherapy is ineffective in treating or any other disease, and can cause a worsening in multiple sclerosis symptoms. The stinger consists of three parts: a stylus and two barbed slides (or lancets), one on either side of the stylus. The bee does not push the stinger in but it is drawn in by the barbed slides. The slides move alternately up and down the stylus so when the barb of one slide has caught and retracts, it pulls the stylus and the other barbed slide into the wound. When the other barb has caught, it also retracts up the stylus pulling the sting further in. This process is repeated until the sting is fully in and even continues after the sting and its mechanism is detached from the bee's abdomen. When a honey bee stings a person, it cannot pull the barbed stinger back out.

It leaves behind not only the stinger, but also part of its abdomen and digestive tract, plus muscles and nerves. This massive abdominal rupture kills the honey bee. Honey bees are the only bees to die after stinging. Asked by: Charles Hills, Exeter Honey bee stings have a barbed ratchet mechanism that pulls the stinger into the initial wound. This didnвt evolve as a suicide mechanism в honey can pull their stings out after stinging other insects. Itвs meant to drive the stinger in as deep as possible; it just happens that mammal skin is too fibrous to release the sting, so the abdomen is torn open when the bee tries to escape afterwards. Honey bees are the only species to suffer this fate, but the cost to the hive of losing some workers is worth it for an improved ability to repel honey thieves.
