What is Hymenoptera allergy?
Hymenoptera venom allergy (HVA) is defined as systemic allergic or anaphylactic reactions that occur in response to stings of insects of the Hymenoptera order. In central and western Europe, this involves most commonly stings by yellow jackets and honey bees, and less frequently stings by hornets or bumble bees.
Why are they called Hymenoptera?
The name Hymenoptera is derived from the Greek words “hymen” meaning membrane and “ptera” meaning wings. It is also a reference to Hymeno, the Greek god of marriage. The name is appropriate not only for the membranous nature of the wings, but also for the manner in which they are “joined together as one” by the hamuli.
What is Hymenoptera venom?
All Hymenoptera venoms contain low-molecular-weight substances, such as biogenic amines, phospholipids, amino acids, and carbohydrates, as well as peptides, such as melittin, apamin, and kinins, which contribute to the toxic effect but which—except melittin—are probably irrelevant with regard to allergies.
Where are Hymenoptera located?
Except in the polar regions, they are abundant in most habitats, particularly in tropical and subtropical regions. Collectively, the Hymenoptera are most important to humans as pollinators of wild and cultivated flowering plants, as parasites of destructive insects, and as makers of honey.

What is bee venom immunotherapy?
