“…K. solenopsae has a more constant presence with fluctuating yet usually detectible infection levels. Successive epizootics of both pathogens can result in prolonged pressure, or stress, on fire ant populations (Briano et al 2006). Colony decline was observed to be faster when simultaneous infections of the two microsporidia occurred in the laboratory .…”

“…New surveys for V. invictae and K. solenopsae were conducted from 2001 to 2005 in several central and Northern provinces (temperate and subtropical) of Argentina and in limited areas of Paraguay, Brazil, Chile, and Bolivia [57], including large western regions previously unexplored. A total of 2,064 colonies were sampled in 262 sites in roadsides, pastures, and recreational areas.…”

We review the fire ant research conducted by the ARS-South American Biological Control Laboratory (SABCL) since 1987 to find a complex of natural enemies in southern South America and evaluate their specificity and suitability for field release as self-sustaining biological control agents. We also include those studies conducted by the ARS-Center for Medical, Agriculture, and Veterinary Entomology in the United States with the SABCL collaboration. Ecological and biological information is reported on local fire ants and their microsporidia, nematodes, viruses, phorid flies, eucharitid wasps, strepsiptera, and parasitic ants. Their biology, abundance, distribution, detrimental effect, field persistence, specificity, and phenology are discussed. We conclude that the objectives of the ARS program in South America are being achieved and that the pioneering studies have served to encourage further investigations in the United States and other countries and advanced the implementation of biological control programs to decrease imported fire ant densities and damage. Still, several promising organisms should be further investigated for eventual field release in the near future.

“…Jouvenaz et al (1980) and Briano et al (1995cBriano et al ( , 2006 reported that 8-13% of fire ant colonies were infected with T. solenopsae in South America. The prevalence of T. solenopsae across sites, however, was higher in South America.…”
