The invasive red imported fire ant, Solenopsis invicta Buren (hereafter, fire ants), is a significant threat to public health and a danger to livestock, pets and wildlife due to their venomous stings. The fire ant has invaded many countries and regions and has become a globally significant pest. The current major tool to manage fire ants are synthetic insecticides that are used largely as stomach poisons in bait products or contact insecticides in spray, broadcast, drench, and dust products for area and nest treatments. In addition to these insecticide products, repellants and fumigants can also be useful in some unique scenarios. The ever-increasing public concern about the potential adverse effects of synthetic insecticides on health and the environment has been a driving force for searching for safer alternatives to control fire ants. Tremendous effort has been made in developing biologically-based control for managing fire ants; however, natural products continue to be one of the most attractive sources of safe alternatives to synthetic insecticides. Here, we summarized the synthetic insecticides that are currently used in managing fire ants, available alternative products in the current market, and academic efforts in searching for fire ant natural toxins, repellants and fumigants.

Imported Fire Ant

Sites receiving repeated broadcast applications of fenoxycarb and hydramethylnon baits for red imported fire ant, Solenopsis invicta Buren, control were examined for impact of bait treatments on ant diversity in southeastern Arkansas. Ants collected from sugar baits belonged to three subfamilies and 25 species. As compared with checks, native ant species increased on fenoxycarb-treated plots and decreased on hydramethylnon-treated plots. Except for S. invicta, ants within the subfamily Myrmicinae practically disappeared from hydramethylnon-treated plots. Sensitivity of ants in the subfamilies Formicinae and Dolichoderinae to hydramethylnon and fenoxycarb was comparatively low. As a consequence, fenoxycarb shows promise for the integrated management of imported fire ants when broadcast applications are desirable.

Beauveria bassiana (Balsamo) Vuillemin GHA strain was tested alone and in combination with different rates of bifenthrin for control of red imported fire ant, Solenopsis invicta Buren, in potted nursery medium. The fungus killed fire ant workers in the potting medium, but was not effective at eliminating infestations in all containers. Bifenthrin at a rate of 1.18 kg Talstar™ (nursery granular, 0.2% Al) per m3 soil alone performed better than B. bassiana alone; however, bifenthrin was also inconsistent in eliminating fire ants from all pots over the 4 yrs of the study. When B. bassiana was combined with reduced rates (1/4 and 1/2) of bifenthrin in 2001, infestations were eliminated from treated pots within 96 h each time workers were added to the pots for the 7-wk test period. The number of infested bifenthrin + B. bassiana-treated pots was significantly lower than the number of infested untreated pots on all 19 sampling dates in 2001. Use of bifenthrin + B. bassiana was as effective or more effective than use of bifenthrin alone and could save growers as much as 15 to 40%.

Imported Fire Ant

As a severe invasive pest, red imported fire ant (Solenopsis invicta Buren) had important effects on ecosystem of its infected areas. Here, we surveyed impact of S. invicta on populations of two banana insect pests, banana skipper (Erion tatorus Evans) and banana stephanitis (Stephanitis typical Distant). The results showed that influences of S. invicta on population of E. tatorus and S. typical depend on weed coverage degree of banana plantations. Comparing to the areas without S. invicta, banana skipper population was reduced by 39.2%, 41.4% and 23.4% respectively, in high, moderate and low weed coverage of banana plantations with S. invicta invasion. Banana stephanitis population was reduced by 17.8%, 43.0% and 39.2% respectively, in high, moderate and low weed coverage of banana plantations with S. invicta invasion.

Predatory Ants

Abstract Multiple predatory ant species, including the red imported fire ant, Solenopsis invicta (Buren) (Hymenoptera: Formicidae), have been reported to attack ixodids (Ixodida: Ixodidae), but evidence has largely been circumstantial. When living lone star tick, Amblyomma americanum (L.) (Acarina: Ixodidae), eggs, and unfed and blood-engorged larvae, nymphs, and adults were deployed on bait transects with hot dog slices and dead house flies, Musca domestica L., in West, Central, and South Texas. The various ixodid life stages were not attacked while ants were strongly recruited to the hot dog and M. domestica baits. Similarly, when the same ixodid life stages and other baits were placed adjacent to colonies of two ant species (red harvester ant, Pogonomyrmex barbatus (Smith) and the red imported fire ant, Solenopsis invicta Buren) the ixodids were not preyed upon while hot dog slices and dead M. domestica were immediately attacked. Some ant species dragged blood-engorged adult ixodids and eggs away from the colony entrance, where they were originally placed, and discarded them. Evidence and mechanisms for allomone-based ant deterrence in the genera Amblyomma, Dermacentor, and Rhipicephalus (metastriate ixodids) are discussed. Protection of ixodids from predatory ants helps to explain why metastriate ixodids remain problematic worldwide despite the presence of predaceous ants.

The decline of the red imported fire ant, Solenopsis invicta Buren (RIFA) following an application of fenoxycarb bait and the subsequent reinfestation from small, incipient colonies to large, mature colonies was studied in south Mississippi. Field colonies were rated using the numerical colony classification system of Lofgren and Williams (1982). The study site was considered RIFA free (98.9% decrease in pretreat population index) 3 months after a fenoxycarb bait treatment. Small incipient colonies categorized in class 7 (100–1,000 workers and worker brood present) appeared in the test site about 4 months after bait application. Mature colonies in classes 9 and 10 (10,000–50,000 workers present with worker brood and more than 50,000 workers with worker brood present, respectively) were detected after 12–15 months of development.

Imported Fire Ant

Classification of red imported fire ant, Solenopsis invicta Buren, colonies as monogyne or polygyne by using differences in worker size (head widths) was compared to PCR discrimination of alleles for colony social form. Maximum head widths were significantly different between the two social forms, but reliable assignment of social form based on head widths was not possible because of considerable overlap in sizes among ants in the two social forms.
