| Abstract: | 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 insecticides should be eliminated. |
