The invasive Red Imported Fire Ant (Solenopsis invicta Buren) is well established at two locations in the Brisbane area, and we report a patient with anaphylaxis after a sting. The potential for anaphylactic events in Australia due to S. invicta will be greater than for native ants because of its unusual venom, its habit of forming supercolonies in grassy areas, and its aggressive group territorial defence, which can result in multiple stings. 

Anaphylaxis caused by stings from the Solenopsis invicta, lava-pés ant or red imported fi re ant*

Considering the clinical manifestations and images of wheals and blisters on the patient’s feet at the time of syncope, this report should serve as a warning for the diagnosis and treatment of this condition and even for counseling and prevention regarding patients exposed to this risk.

Safety Considerations for Handling Imported Fire Ants (Solenopsis Spp.) in the Laboratory and Field

All workers who are exposed to imported fire ants should be familiar with the symptoms of anaphylaxis and be prepared to seek immediate medical assistance if they or their coworkers are stung and show symptoms of hypersensitivity.

Fire Ant, a New Hazard to Military Camps in Taiwan

Information is provided for military personnel on how to avoid this hazard and on the appropriate treatment for ant sting, because military personnel have many routine duties outdoors, their chance of coming into contact with red imported fire ants in infested areas is greater than that of urban citizens.

Eradication of two incursions of the Red Imported Fire Ant in Queensland, Australia

Of the five known incursions of the highly invasive Red Imported Fire Ant in Australia, two are regarded to have been eradicated and eradication is still considered to be feasible with long-term commitment and support.

Ant venom immunotherapy is feasible and highly efficacious, however, the limited geographical distribution of each species presents a major challenge to making venom extracts available for clinical use.

Ant allergy in Asia and Australia

Clinicians in Asia need to be aware of ant stings as a cause of severe allergic reactions and certain species that cause allergic reactions are unique to Asia and Australia and deserve further research.

Deaths caused by imported fire ant stings are rare but are likely to become more common as the fire ant population expands, and the importance of recognizing the characteristic skin lesions produced by fire ants is stressed.

Fatal anaphylaxis following jack jumper ant sting in southern Tasmania

There is potential to prevent deaths by careful education of people with known allergy, prescribing of adrenaline for auto‐injection and development of an effective hyposensitisation therapy.

Wasp sting mortality in Australia

All patients with a history of systemic Hymenoptera sting allergy should undergo assessment for immunotherapy and carry adrenalin, as five of the seven victims had prior histories of wasp or bee venom allergy, but none carried injectable adrenalin.

A large number of wasp‐allergic patients with RXN3 responses to wasps could not be offered immunotherapy and a similar problem exists in the lack of availability of specific reagents for ant‐ and tick‐induced dyspnoea or hypotension.

Fire ants: a continuing community health threat in South Carolina.

Imported fire ants are now firmly established in all 46 counties of South Carolina and patients in recently infested areas seem to be more likely to seek treatment since they are relatively unfamiliar with the multiple, painful IFA stings and pustules.

Although self-selection may have provided an exaggerated view of the frequency with which reactions to the stings of jack jumper ants become generalized, the problem is clearly one of considerable magnitude which requires further research and attention.
