Abstract The effects of the red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), on cotton aphid, Aphis gossypii Glover, populations and its predation of bollworm, Helicoverpa zea (Boddie), and beet armyworm, Spodoptera exigua (Hübner), (both Lepidoptera: Noctuidae) eggs were evaluated in cotton under field conditions during 2001 and 2002 in central and northern Texas. In central Texas, cotton aphid populations were ≈5.5 times greater and predation of sentinel bollworm… 


Red imported fire ants did not significantly reduce the abundance of non-aphid herbivores in either year of the authors' field experiment, suggesting that fire ants are not important biological control agents of these insects in tomato.

Quantifying the impacts of symbiotic interactions between two invasive species: the tawny crazy ant (Nylanderia fulva) tending the sorghum aphid (Melanaphis sorghi)

The establishment of new symbiotic interactions between introduced species may facilitate invasion success. For instance, tawny crazy ant (Nylanderia fulva Mayr) is known to be an opportunistic

Effects of Solenopsis invicta (Hymenoptera: Formicidae) and Its Interaction with Aphids on the Seed Productions of Mungbean and Rapeseed Plants

One of the main mechanisms whereby red imported fire ants affect the crop yield is by compromising the reproduction processes, as indicated by this study.

Arthropod prey of imported fire ants (Hymenoptera: Formicidae) in Mississippi sweetpotato fields

Imported fire ant foraging may reduce the number of insect pests in sweetpotato fields, as these insect orders contain various economically important pests ofsweetpotato.

Evaluation of Sampling Methods and Development of Sample Plans for Estimating Predator Densities in Cotton

The greater cost-reliability of the beat bucket sampling method and its ease of use is of particular advantage in assessing predator densities in a commercial cotton field monitoring program.
