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… 

Effects of insecticide treated green peach (M. persicae) aphids on the survival and development of Coccinellidae

Flonicamid allows for the possibility of longer-term lady beetle survivorship, where other pesticides such as synthetic pyrethroids do not, and indicates that sulfoxaflor treated aphids have a toxic effect on Coccinellids and may be a poor choice for use in similar fields.

Residual Susceptibility of the Red Imported Fire Ant (Hymenoptera: Formicidae) to Four Agricultural Insecticides

The results of this study demonstrate the wide range in responses of fire ants to four insecticides that are labeled and commonly used on numerous agricultural crops throughout the United States and suggest the possibility of using a discriminating dose of lambda-cyhalothrin to control the target pest species while conserving fire ants in the agricultural systems in which their predatory behavior is beneficial to the integrated pest management program.

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.

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 to

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.


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.



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.

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.

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.

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.

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.

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 the

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.

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 on
