Abstract:Spiders constitute some of the most important predators of the cotton fleahopper, Pseudatomoscelis seriatus (Reuter), in cotton fields in East Texas. Simulation studies showed that spiders were worth three times the value of insects as predators of the cotton flea-hopper. To assess the economic value of spiders, the TEXCIM40 model was used to forecast the benefits of spiders and predaceous insects in the management of cotton fleahoppers. Forecasts of crop losses attributable to cotton fleahoppers cannot be accurate if the effects of spiders and other predators are not assessed. Benefits of generalist predators ranged from $0.86 to $15.50/0.4047 ha (1 acre) during the 5 yr of data used in simulations. However, potential benefits of > $60.0010.4047 ha may be possible in certain cotton fields.
