Insect sting allergy is the term commonly given to the allergic response of an animal in response to the bite or sting of an insect. [1] Typically, insects which generate allergic responses are either stinging insects ( wasps , bees , hornets and ants [ 2 ] ) or biting insects ( mosquitoes , ticks ).
Feeding bites may also contain digestive enzymes, as in spiders; spider bites have primarily evolved to paralyse and then digest prey. A sting comes from the abdomen; in most insects (which are all largely hymenopterans), the stinger is a modified ovipositor, [16] which protrudes from the abdomen. The sting consists of an insertion wound, and ...
[10] [21] Foods are the most common trigger in children and young adults, while medications and insect bites and stings are more common in older adults. [3] Less common causes include: physical factors, biological agents such as semen , latex , hormonal changes, food additives and colors, and topical medications. [ 18 ]
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 pain in most people, [ 1 ] allergic reactions may occur in people with allergies to venom ...

Mosquito bite allergies occur more often where insect bites are frequent. Consequently, cases (as well as various other allergic disorders) are more prevalent in tropical climates, underdeveloped areas, areas dominated by poverty, poor hygiene, and/or unawareness of these diseases, and urban areas plagued by social inequality, juvenile ...
The Skeeter syndrome should not be confused with another type of reactivity to mosquito bites, severe mosquito bite allergy (SMBA). SMBA is most often an Epstein-Barr virus-associated lymphoproliferative disease that complicates ~33% of individuals with chronic active Epstein-Barr virus infection or, in extremely rare cases, individuals with Epstein-Barr virus-positive Hodgkin disease or an ...
The hereditary form (HAE) often goes undetected for a long time, as its symptoms resemble those of more common disorders, such as allergy or intestinal colic. An important clue is the failure of hereditary angioedema to respond to antihistamines or steroids, a characteristic that distinguishes it from allergic reactions. It is particularly ...
