Abstract Red imported fire ants, Solenopsis invicta (Buren) (Hymenoptera: Formicidae), are an invasive species found in high densities throughout southeastern agricultural systems. We tested the hypothesis that fire ants tend cotton aphids, Aphis gossypii Glover (Homoptera: Aphididae), and thus release them from predation by lady beetle larvae, Coccinella septempunctata L. and Hippodamia convergens Guerin-Meneville (Coleoptera: Coccinellidae), and green lacewing larvae, Chrysoperla carnea… 

No Enemies Needed: Cotton Aphids (Hemiptera: Aphididae) Directly Benefit from Red Imported Fire Ant (Hymenoptera: Formicidae) Tending

This study finds strong evidence that cotton aphids receive direct benefits from their relationship with fire ants, and hypothesizes that the increase in aphid population size results from altered feeding behaviors in the presence of ants.

Solenopsis invicta (Hymenoptera: Formicidae), Defend Phenacoccus solenopsis (Hemiptera: Pseudococcidae) Against Its Natural Enemies

Testing the hypothesis that ant tending can increase the densities of the mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), and reduce the density of theMealybug's predatory and parasitic enemies, the lady beetle, Menochilus sexmaculata Fabricius, and the parasitoid wasp showed thatAnt tending significantly increased the survival of mealybugs.


Results from this experiment established peaks of aphid infestation throughout the growing season and location of different cotton aphid life forms on the plant, indicating that the pink spotted lady beetle may be a good candidate for augmentative biological control of Cotton aphid on strawberry in the greenhouse.

Effect of the red imported fire ant on cotton aphid population density and predation of bollworm and beet armyworm eggs.

The results of this study show that although S. invicta may promote aphid populations early in the growing season, it is an important predator of bollworm and beet armyworm eggs later in the season.

Feeding Damage from Cotton Aphids, Aphis gossypii Glover (Hemiptera: Heteroptera: Aphididae), in Cotton with Colored Fiber Intercropped with Fennel

The severity of plant damage related to infestation by the cotton aphid and its predation by spotless ladybird beetle, Cycloneda sanguinea (L.) and green lacewing and Chrysoperla carnea and parasitism are investigated.

Rise and Fall of Cotton Aphid (Hemiptera: Aphididae) Populations in Southeastern Cotton Production Systems

Arthropod natural enemies were most abundant after epizootics and may have suppressed aphid populations late in the season, and Seed cotton yield, and lint quality were not affected by aphicide applications in any year of the study.

Assessment of Fennel Aphids (Hemiptera: Aphididae) and their Predators in Fennel Intercropped with Cotton with Colored Fibers

It is hypothesized that intercropping can be used as an alternative pest management strategy to reduce aphid yield loss in fennel and apparently promoted biocontrol offennel aphid in fENNel.

Consequences of Mutualisms Between Aphids and an Invasive Ant to Arthropod Communities and Their Host Plants

Investigation of whether plant trichomes hinder red imported fire ants, Solenopsis invicta Buren, as biological control agents in soybean, field and greenhouse experiments found that fire ants more strongly reduced plant damage by herbivores on pubescent plants, but this effect did not translate into greater yield fromPubescent plants at high fire ant densities.

The Influence of Lasius neoniger (Hymenoptera: Formicidae) on Population Growth and Biomass of Aphis glycines (Hemiptera: Aphididae) in Soybeans

It is argued that aphid-tending by ants can have an influence on natural field populations of soybean aphids, both in the presence or absence of natural enemies.



Interactions between Solenopsis invicta (Hymenoptera : formicidae), Rhopalosiphum maidis (Homoptera : aphididae), and the parasitoid Lysiphlebus testaceipes cresson (Hymenoptera : aphidiidae)

In the presence of the red imported fire ant, adult emergence of the parasitoid Lysiphlebus testaceipes Cresson from laboratory colonies of the corn leaf aphid, Rhopalosiphum maidis (Fitch), was reduced and the removal and destruction of parasitized aphids was removed.

Aphid-ant interaction reduces chrysomelid herbivory in a cottonwood hybrid zone

In a cottonwood (Populus) hybrid zone, Chaitophorus aphids attract aphid-tending ants which subsequently reduce herbivory by the leaf-feeding beetle, Chrysomela confluens, which causes beetle defoliation of immature trees.

Melon Aphid (Homoptera: Aphididae) Control by Inundative Convergent Lady Beetle (Coleoptera: Coccinellidae) Release on Chrysanthemum

Release of commercially available convergent lady beetles can provide augmentative control of relatively high aphid densities on small potted plants and there was a density-dependent functional response in predation; beetles consumed more aphids when released on plants with higher aphid density.

Tending Ants (Hymenoptera: Formicidae) Regulate Dalbulus quinquenotatus (Homoptera: Cicadellidae) Population Dynamics

Ants were observed protecting leafhoppers from nabid predators, although this protection did not significantly influence leafhopper population size or length of egg to adult development.

Intraguild Predation of Beneficial Arthropods by Red Imported Fire Ants in Cotton

It is suggested that red imported fire ants are major intraguild predators of important beneficial arthropods in cotton.

Interactions in entomology: aphids, aphidophaga and ants in pecan orchards.

Three methods for conserving aphidophaga were tested in multiple factor controlled field experiments over two seasons in four pecan orchards, finding significant interaction effects were found in blackmargined aphid (Monellia caryella (Fitch), ladybeetle (Coccinellidae), and red imported fire ant abundance.

Prey of the Red Imported Fire Ant (Hymenoptera: Formicidae) in Oklahoma Peanuts

Abstract The red imported fire ant, Solenopsis invicta Buren, is an important predator in some cropping systems in the United States, particularly sugarcane and cotton, where it preys on key pests

Behavior of Solenopsis invicta (Hymenoptera: Formicidae) in Pecan Orchards

Orchards provide an important habitat for the red imported fire ant, Solenopsis invicta Buren, and orchards from middle to southern Georgia were heavily infested, and S. Invicta was a major predator of eggs, larvae, and pupae of a green lacewing, Chrysoperla rufilabris, but had little effect on the eggs of Hippodamia convergens Guerin-Meneville.

Plant Protection as a Consequence of an Ant‐Membracid Mutualism: Interactions on Goldenrod (Solidago Sp.)

In central New York, two chrysomelid beetles, Trirhabda virgata and T. borealis, frequently cause severe defoliation of tall goldenrod, Solidago altissima, and two smaller, less aggressive an species (Prenolepis imparis and Myrmica sp.) do not affect either larval or adult beetle densities.


The presence of a few red imported fire ants, Solenopsis invicta Buren, workers on aphid bearing cotton plants reduced aphid predator effectiveness in the laboratory. The predators Hippodamia
