A bee sting is the wound and pain caused by the stinger of a female bee puncturing skin. Bee stings differ from insect bites, with the venom of stinging insects having considerable chemical variation. The reaction of a person to a bee sting may vary according to the bee species. While bee stinger venom is slightly acidic and causes only mild ...
Apitoxin. Apitoxin or bee venom is the venom produced by the honey bee. It is a cytotoxic and hemotoxic bitter colorless liquid containing proteins, which may produce local inflammation. It may have similarities to sea nettle toxin. [ 1]
Alarm pheromone. Two main alarm pheromones have been identified in honeybee workers. One is released by the Koschevnikov gland, near the sting shaft, and consists of more than 40 chemical compounds, including isopentyl acetate (IPA), butyl acetate, 1-hexanol, n -butanol, 1-octanol, hexyl acetate, octyl acetate, n -pentyl acetate and 2-nonanol.

In 1609, the English beekeeper Charles Butler observed that the sting of a bee released a liquid. This liquid attracted other bees, which then began to sting en masse. [15] Butler thus demonstrated for the first time the effect of an alarm pheromone of bees, which was identified as isoamyl acetate in the 1960s. [16]
Melittin is the main compound in bee venom, accounting for the potential lethality of a bee sting, which causes an anaphylactic reaction in some people. [ 5] At the sites of multiple stings, localized pain, swelling, and skin redness occur, and if bees are swallowed, life-threatening swelling of the throat and respiratory passages may develop.
