Venoms of ants in the genus Solenopsis have unusual components not found in venoms of other stinging Hymenoptera. Most Hymenoptera venoms contain proteins that are responsible for the painful sting. The venom of the Red Imported Fire Ant, Solenopsis invicta, contains some protein components but the major components are piperidine alkaloids known as Solenopsins. Solenopsins are the components of the venom responsible for pain. They are also responsible for the pustule that form on the skin after a sting. The Solenopsins are not responsible for the allergic reaction that some have to fire ant stings. Allergic reactions are triggered by some of the proteins in the venom.

  1. Thanks for the interest in this stingy topic!
    There is an applied overview on the fire ants venom composition given in the book chapter below and included references:

    Fox, E.G.P. Venom toxins of fire ants. In Venom genomics and proteomics; Gopalakrishnakone, P., Calvete, J.J.,Eds.; Springer: Dordrecht, The Netherlands, 2014; pp. 1–16.

    It can be freely obtained from my online repository profiles (ResearchGate, Academia, etc).
