Field studies were conducted in Vero Beach, FL, in November 1993 and 1994 to determine the rate of removal of Logic® fire ant bait by red imported fire ants, Solenopsis invicta Buren, from treated improved pastures of bahiagrass, Paspalum notatum Fluegge. Logic® fire ant bait was applied at the maximum label rate of 1.68 kg/ha (16.8 g ai/ha). In 1993, fire ants had removed approximately 35% of the granules by 4 h after application and about 67% by 12 h. By 24 h, 82% had been removed. By the last count (48 h after application) about 95% had been removed. In 1994, the granules were removed slightly faster, with about 60% removed by 4 h and 92% by 24 h after application. Nearly 97% of the granules had been removed by the last count (30 h after application). In 1993, several mounds of the ant, Dorymyrmex bureni Trager, were found in the test area while in 1994 only red imported fire ant mounds were present. The results indicate that Logic® fire ant bait is found and harvested very rapidly by fire ant workers under favorable foraging conditions and that a dose which will provide effective population reduction can be obtained in 12 to 24 h after application at 1.68 kg/ha. Additionally, with its low use rate, specificity to certain insects and rapid removal by fire ants, Logic® fire ant bait when used according to label poses minimal risk to non-target organisms.

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.

Abstract The use of insecticide remains the frontline method in controlling red imported fire ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae), one of the worst invasive ants in the world. Neonicotinoids are effective ingredients in toxic baits for suppressing S. invicta population. To search for new and effective insecticides, the toxicity and sublethal effects of triflumezopyrim, a novel neonicotinoid analog, were evaluated against S. invicta. No high mortality of ants was observed after they fed on sugar water containing 120 μg/ml triflumezopyrim for 72 h; however, 100% mortality was achieved after ants fed on sugar water containing 10 μg/ml triflumezopyrim for 2 wk. Furthermore, at 10 μg/ml, triflumezopyrim did not inhibit ant food consumption within the 7-d treatment period. These results indicate that triflumezopyrim is a slow acting toxin and may be qualified as bait toxin for managing red imported fire ants. At 1 μg/ml, triflumezopyrim did not cause any significant effect on colony growth within 56 d and did not inhibit the food consumption during the whole trial period. At 10 μg/ml, triflumezopyrim displayed a significant reduction of aggressiveness during confrontation with native ants, resulting in higher mortality than the ants in the control. However, at 1 μg/ml, triflumezopyrim did not show any significant impact on both aggressiveness and mortality of the red imported fire ants.

Loblolly pines, Pinus taeda L., were banded in three seed orchards in Georgia to prevent the red imported fire ant, Solenopsis invicta (Buren), from tending infestations of striped pine scales, Toumeyella pini (King). Ant activity had no effect on female scale insect survival as numbers per shoot were never significantly different between check and banded trees in any of the orchards. Parasitism of females rarely differed between treatments, with higher rates twice in one orchard on unbanded trees and once in another orchard on banded trees. There also appeared to be no treatment effects on predator numbers. Coincident populations of the mealybug Oracella acuta (Lobdell) and the woolly pine scale, Pseudophilippia quaintancii Cockerell, on the shoots also were unaffected by the presence of fire 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.

We evaluated the bioactivities of compounds from Cicuta virosa L. var. latisecta Celak. against red imported fire ants (Solenopsis invicta Buren) under field and laboratory conditions. The compounds were as follows: methanol extract; petroleum ether, chloroform, and ethyl acetate fractions from the methanol extract; and the active compound isoimperatorin, which was isolated from the chloroform-fraction. The 7 d LC50 values of the methanol extract, petroleum ether, chloroform, and ethyl acetate fractions and isoimperatorin toward micrergates were 111.20, 214.45, 40.90, 569.67, and 25.73 mg/kg, res­pectively. The corresponding LC50 values toward macrergates were 155.78, 308.38, 75.01, 776.75, and 42.77 mg/kg, res­pectively. Under field conditions, baits containing 0.2% methanol extract, 0.1% chloroform fraction, and 0.05% isoimperatorin efficiently controlled S. invicta, with effectiveness percentages of 95.56%, 97.78%, and 95.56%, respectively on the 30th day after bait application. Such effectiveness percentages were not significantly different from that obtained using the positive control fipronil. The present study showed that C. virosa L. var. latisecta has potential as a natural control agent for the red imported fire ants.

We evaluated the effects of invasive red imported fire ants (RIFAs), Solenopsis invicta Buren, on native ant communities at three habitats in South China. By using paired control and treatment plots, the change in diversity and community structure of native ants due to the invasion of red imported fire ants could be observed. Ant species richness was reduced by 46 and 33% at RIFA-infested lawn and pasture habitats, respectively; however, the ant species richness in the lichee orchard was not affected by red imported fire ants. Our results indicated that red imported fire ants became one of several dominant species or the only dominant species in all three habitats in South China.
