In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] 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.
The stings of the red imported fire ant in animals are painful, and may prove life-threatening. [70] In dogs, stings from the red imported fire ant can cause pustular dermatosis, a condition where pustules appear in crops as a result of the ant sting. [71] After getting stung, the immediate response consists of erythema and swelling.
Fire ants also sting humans, Frye says, which can cause small pus-filled bumps on the skin, according to the Cleveland Clinic. Other symptoms: Ant bites are typically painful and itchy.
Solenopsis are stinging ants, and most of their common names reflect this, for example, ginger ants and tropical fire ants. Many of the names shared by this genus are often used interchangeably to refer to other species of ant, such as the term red ant , mostly because of their similar coloration despite not being in the genus Solenopsis.
Red bulldog ant. Bulldog ants, from the genus Myrmecia, are native to Australia, with all but one of the ninety or so species found on the continent. Belonging to the ant subfamily Myrmeciinae, they are among the most primitive extant ants in the world. This species is known to cause some fatalities in sensitive humans. [11] Bullet ant
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.
This leads to prolongation of action potentials, which is associated with the pain from bullet ant stings. Overall, poneratoxin disrupts normal function of voltage-gated sodium channels in both vertebrates and invertebrates. It causes repetitive firing and prolongation of action potentials, particularly in the central nervous system of insects. [4]
The green-head ant (Rhytidoponera metallica) was the only ant other than Myrmecia species to cause anaphylaxis in patients. [257] Dogs are also at risk of death from Myrmecia ants; renal failure has been recorded in dogs experiencing mass envenomation , and one dog was euthanised due to its deteriorating health despite treatment.
