Red imported fire ants,Solenopsis invicta Buren, are effective predators of the boll weevil,Anthonomus grandis Boheman, in east Texas cotton fields. Boll weevils caused no economic loss in 11 years due to mortality attributed primarily to ants. Removal of the ants resulted in an increase in crop damage by the boll weevil. Insecticides used for cotton pests greatly reduce the abundance of the ants. To capitalize on this effective predation of boll weevils by ants, unnecessary applications of… Expand

Residual Susceptibility of the Red Imported Fire Ant (Hymenoptera: Formicidae) to Four Agricultural Insecticides
Abstract The red imported fire ant, Solenopsis invicta Buren, is an abundant predator in cropping systems throughout its range. It has been documented to be an important predator of numerous cropExpand
The red imported fire ant, Solenopsis invicta, modifies predation at the soil surface and in cotton foliage
It is indicated that fire ant suppression is associated with decreases in the density of honeydew-producing insects, and increasing abundance of whiteflies on the plants coincided with a decrease in egg predation at the soil surface, which suggests the mutualism between ants and whiteflies may lead to a shift in predation intensity from edaphic towards plant-based food webs.

Role of Ants in Pest Management
In view of their abundance, their stability as populations, and their feeding habits, ants have a major influence in many habitats and may be useful in pest management, but such positive attributes must be weighed against possible disadvantages. Expand
Impact of the invasion of the imported fire ant
The impact of the imported fire ant (IFA) is complex, in large part, because several very different species of “Fire Ants” have invaded and one of these has two forms, all of which are hard toExpand
This catalogue presents the 597 species of Coleoptera Curculionoidea (3 familias) from Nicaragua. The geographical Distribución, synonyms, host plants and natural enemies are given for each species.Expand
Sustainable control of infestations using image processing and modelling
Novel predator/prey modelling algorithms assess control requirements for the UAV system, which is designed to deliver measured quantities of naturally beneficial predators to combat pest infestations within economically acceptable timeframes. Expand


Killing power of the red imported fire ant [Hym.: Formicidae]: a key predator of the boll weevil [Col.: Curculionidae]
The red imported fire ant was identified as a key predator of the boll weevil,Anthonomus grandis Boheman, during the summer of 1981 and when this predation was combined with other natural mortality factors, the weevil population density throughout the season never exceeded levels that required control measures. Expand
Inaction levels for the red imported fire ant, Solenopsis invicta (Hym., Formicidae): a predator of the boll weevil Anthonomus grandis (Col.: Curculionidae)
The net replacement rate per generation is 1.0 which, in this case, indicates a stable boll weevil population. Expand
Fortuitous Biological Suppression of the Boll Weevil by the Red Imported Fire Ant
The efficacy of the red imported fire ant as a predator of larval stages of the boll weevil was evaluated in 2 areas of Texas. Expand
Failure of the Red Imported Fire Ant to Reduce Entomophagous Insect and Spider Abundance in a Cotton Agroecosystem
Large numbers of the red imported fire ant, Solenopsis invicta Buren, were unable to pauperize the predator arthropod fauna of a cotton field in east Texas, suggesting that it is a fairly specialized predator though probably a polyphagous scavenger. Expand
Biology and control of imported fire ants.
The purpose here is to review this research, although because of space limitations, much of the recent work concerning the chemical toxicology and persistence of mirex, the chemical currently used for control of imported fire ants. Expand
Interspecific Association Between the Red Imported Fire Ant (Hymenoptera: Formicidae), Aphids, and Some Predaceous Insects in a Cotton Agroecosystem
Interspecific association between the red imported fire ant, Solenopsis invicta Buren, and several insect inhabitants of east Texas cotton fields was analyzed and indicated that ants occur in combination with aphids and several hemipteran predators more frequently than expected on the basis of chance alone. Expand
Manipulation of Red Imported Fire Ants in a Trap Crop for Boll Weevil Suppression
Red imported fire ants were introduced into an early-planted East Texas cotton plot, while ants were essentially removed from a control plot with Mirex. In the ant plot, predation by ants reduced theExpand
Pheromone Trap Index System for Predicting Need for Overwintered Boll Weevil Control
The trap index method was more accurate than field scouting in providing a warning of overwintered weevil infestation before squares of a suitable size for oviposition were present and was equally effective in indicating when overwintering weevil control was unnecessary. Expand
Arthropod Parasites of the Boll Weevil, Anthonomus grandis: 1. an Annotated List
Of 42 species of arthropods that parasitize the boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae), 33 are Hymenoptera, 6 are Diptera, 1 is Coleoptera, and 2 are Acarina. Notes onExpand
