The toxicology of fire ant venom is relatively well studied. The venom plays a central role in the biology of Red imported fire ants , such as in capturing prey, [ 1 ] and in defending itself from competitors, [ 2 ] assailants, [ 3 ] and diseases. [ 4 ]
The venom of fire ants is mainly (>95%) composed of oily alkaloids structurally derived from piperidine (also known as solenopsins) mixed with a small amount of toxic proteins. [ 37 ] [ 38 ] Fire ant stings are painful, characterised by a local burning sensation, followed by urticaria . [ 37 ]
Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting. [3]: 450 First aid for fire ant bites includes external treatments and oral medicines. [citation needed]
Santa Barbara County has spent a total of $15,000 eradicating local populations of red imported fire ants to prevent the invasive species from spreading. ... The venom from an ant's sting can ...
The red fire ant, one of the world’s most invasive species, has been found in Europe for the first time, according to a new study published Monday.
Solenopsin is a lipophilic alkaloid with the molecular formula C 17 H 35 N found in the venom of fire ants (Solenopsis).It is considered the primary toxin in the venom [2] and may be the component responsible for the cardiorespiratory failure in people who experience excessive fire ant stings.
Venom released from the ants' stings can cause "painful pustules on the skin, and can be particularly dangerous, even fatal, to sensitive groups or those with an allergy to the venom," officials ...
Ants belonging to the genus Solenopsis are known as "fire ants" because of the pain caused by their stings, which inject venoms. The venoms of fire ants are characterized by a variety of alkaloids known as solenopsins (2-methyl-6-alkylpiperidines) that exhibit necrotic , hemolytic , antibiotic , and toxic properties. [ 12 ]
