In this study, we analyzed the potential distribution of red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), in response to climate change in South Korea using CLIMEX, a species distribution model. We further attempted to evaluate the risk of the distribution/invasion and subsequent dispersion by considering climatic suitability, and functional characteristics of cities and covered cultivated areas. The climatic suitability has extended from the southern and coastal regions to inland regions due to climate change. The number of areas with EI (Ecoclimatic Index) values of more than 20 was 9 (12%) in the current climate; the value was assumed to increase to 23% (2040), 24% (2060), 42% (2080), and 62% (2100) from the South Korea coast to inland. We predicted that May to October would be the most active period in seven domestic high-habitation areas. We also analyzed the invasive risk of the red imported fire ant into covered domestic cultivation areas. Considering climatic suitability, we determined that Jeju, Pohang, Busan, Ulsan, Mokpo, and Gosan would be the most affected areas. This study can provide baseline data for the management of invasive species nationally and for regional control through predictions of the probability of settlement and direction of spread.

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 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.

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

Diets of the red imported fire ant, Solenopsis invicta Buren, and the native fire ant, Solenopsis geminata [F.], were studied in adjacent field colonies in south central Texas. A comparison of solid food diets of the two species revealed a 59% overlap of identifiable arthropods and other solid food matter. The major difference was that S. geminata collected eight times more seeds than did S. invicta. Both species collected liquid food much more frequently than solid food; in fact, an average of 70–80% of successful foragers returned with liquid. Rates of liquid collection were approximately 40% higher for S. invicta than for S. geminata. Foraging rates fluctuated with season but the percent of successful foragers returning with liquid remained relatively constant. Plants and honeydew producing homopterans are the most probable sources of this liquid based on sugar and amino acid analyses of S. invicta foragers. Use of liquid carbohydrate energy sources helps explain how fire ant colonies can collect sufficient food to sustain extremely dense field populations.

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.

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.
