Abstract Using natural venom collected from the red imported fire ant, Solenopsis invicta Buren, we determined the dose of venom necessary to kill 50% of the workers (LD50) of Argentine ants, Linepithema humile (Mayr), and several other ant species that the fire ant may encounter in California. Of the species tested, the Argentine ant was most susceptible to the venom. On a weight-adjusted basis the red imported fire ant was 330 times more resistant to the venom than the Argentine ant.

Venom Isosolenopsin A Delivers Rapid Knockdown of Fire Ant Competitors

It is reported that fire ant queen venom and its major compounds are much quicker to neutralise competitor ants than the more diverse venoms of workers, and these are fundamental aspects in the chemical ecology of the invasive ants which have been long overlooked.

Fire Ants Feed Their Nestmates with Their Own Venom.

Evidence is reported that Solenopsis invicta feed their nestmates with their own venom, indicating that venom in the digestive system is most likely used as an internal antibiotic by fire ants.

Queen venom isosolenopsin A delivers rapid incapacitation of fire ant competitors

The Insecticidal Activities of Fire Ant (Hymenoptera: Formicidae) Venoms Against Plutella xylostella (Lepidoptera: Plutellidae) Larvae

The results of the experiment showed that the larval symptoms induced by fire ant venom include contractile, flaccid paralysis, black coloration and death, and P. xyhstella larvae were most susceptible to S. geminata venom.

Advances in Research on the Venom Chemistry of Imported Fire Ants

Workers of the imported fire ants, including red imported fire ants, Solenopsis invicta Buren, black imported fire ants, S. richteri Forel, and their hybrid (S. invicta × S. richteri), are vicious

Chemical Warfare Among Invaders: A Detoxification Interaction Facilitates an Ant Invasion

The capacity to detoxify a major competitor’s venom probably contributes substantially to its ability to displace S. invicta populations, making this behavior a causative agent in the ecological transformation of regional arthropod assemblages.

Toxicity and utilization of chemical weapons: does toxicity and venom utilization contribute to the formation of species communities?

This study demonstrates that different factors and strategies can contribute to the ability of a species to withstand the pressure of a dominant invader at high abundance, and venom chemistry appears to be only one of several strategies utilized.

Paralyzing Action from a Distance in an Arboreal African Ant Species

The bioassays showed that the toxicity of the Dufour gland contents acts in a time-dependent manner, leading to the irreversible paralysis, and, ultimately, death of the termites.

The influence of semiochemicals on the co-occurrence patterns of a global invader and native species

New insights into chemical communication between invasive and resident species, support existing dominance hierarchy models in ant populations, and help to establish a target specific potential management technique of wide-spread invasive ant species are provided.



Patterns of venom synthesis and use in the fire ant, Solenopsis invicta.

Chemical and Biological Characterization of Venom of the Ant Solenopsis xyloni McCook

Comparing the chem,ical and biological properties of these Sole,nopsis venom in order to possibly determine what is responsible for their different dermatological effects indicates that the venoms of these two species of Solenopsis differ chemically.

Biochemical evolution in fire ant venoms

Exploitation and interference competition between the invasive Argentine ant, Linepithema humile, and native ant species

Interactions between the invasive Argentine ant, Linepithema humile, and native ant species were studied in a 450-ha biological reserve in northern California. Along the edges of the invasion, the


AbstractStinging ants are now recognized as being of considerable public health significance in both temperate and tropical regions. Many species of ants produce venoms that contain powerful algogens

Behavioral interactions of the invasive Argentine ant with native ant species

Interactions between Argentine ants and native species at food resources, causing ants of native species to retreat, may help Argentine ants to displace native species from invaded areas.

Skin responses to the sting of the imported fire ant (Solenopsis saevissima).

The fire ant causes destruction to crops and, according to Travis, 2 as many as 15% of the native fire ants of the South are destructive.

Gaster flagging by fire ants (Solenopsis spp.): Functional significance of venom dispersal behavior

Observations suggest that airborne venom dispersal by workers is context specific rather than temporal caste specific and that workers can control the quantity of venom released.

Aggressive Interactions Between Solenopsis invicta and Linepithema humile (Hymenoptera: Formicidae) Under Laboratory Conditions

Fire ant baits may have long-term effects on intercolonial aggression between S. invicta and L. humile, especially when Argentine ant populations are high in the summer.
