The Oriental hornet (Vespa orientalis) is a social insect species of the family Vespidae. It can be found in Southwest Asia , Northeast Africa , the island of Madagascar (but no reports have been made of its presence on the island for many years), the Middle East, Central Asia, and parts of Southern Europe .

Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. [ 8 ] [ 9 ] Individual hornets can sting repeatedly. Unlike honey bees , hornets do not die after stinging because their stingers are very finely barbed (only visible under high magnification) and can easily be ...
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 ).
Symptoms to note: Bee stings cause moderate pain, which should subside within a few hours. All insect stings can cause life-threatening allergic reactions, and bee stings are no exception.
Unlike most other stings, honey bee workers' stings are strongly barbed and lodge in the flesh of mammals upon use, tearing free from the honey bee's body, killing the bee within minutes. [2] The sting has its own ganglion, and it continues to saw into the target's flesh and release venom for several minutes. This trait is of obvious ...
Vespa tropica, the greater banded hornet, is a tropical species of hornet found in Southern Asia, New Guinea and west Africa, and which has recently been discovered to be an invasive species on the Pacific island of Guam. It is a predator of paper wasps and possesses a potent sting, which can cause extreme pain and swelling.
The Schmidt sting pain index is a pain scale rating the relative pain caused by different hymenopteran stings. It is mainly the work of Justin O. Schmidt, who was an entomologist at the Carl Hayden Bee Research Center in Arizona. Schmidt published a number of works on the subject and claimed to have been stung by the majority of stinging ...
The venom of Vespa luctuosa has the highest recorded toxicity to mice of any wasp species tested. The LD 50 of the venom is 1.6 mg/kg. The toxicity (measured against mice) per weight of Vespa luctuosa venom is higher than that of the larger Asian giant hornet (Vespa mandarinia), which has an LD 50 of 4.0 mg/kg, but which is responsible for many more human deaths than Vespa luctuosa due to the ...
