Abstract
ABSTRACT The economic benefits to cotton producers from Red Imported Fire Ant's (RIFA), (Solenopsis invicta [Buren]) presence in the quarantined counties of Texas, U.S., were estimated for the control of four cotton insect pests: boll weevil (Anthonomus grandis [Boheman]); bollworm (Helicoverpa zea [Boddie]); tobacco budworm (Heliothis virescens [Fabricius]); and cotton fleahopper (Pseudatomoscelis seriatus [Reuter]). The TEXCIM40 plant-herbivore-predator model microcomputer program was used to simulate the multipest system to measure the true benefits of controlling each pest. It was estimated that 0.06 and 0.17 RIFA per plant are needed to save the producer approximately $59 and $122 per ha, respectively, in lost lint caused by the pests considered. The results reported in this study can be used by producers wishing to determine whether it would be cost effective to place multiple applications of chemicals into the field to control the four insect pests considered, or to allow RIFA to control these pest...
