Interpretive Summary:

Technical Abstract: The cereal aphid pest management system is a set of computer programs to help the user manage cereal aphids in winter wheat. The system is maintained on-line by Oklahoma State University. To access the expert system go to http://entoplp.okstate.edu/ then select "Agricultural Models" and "Cereal Aphids Pest Management". The expert system was developed through the cooperative efforts of the USDA-ARS Plant Science and Water Conservation Research Laboratory, Department of Entomology and Plant Pathology, Oklahoma State University, and Site Specific Technology Development Group, Inc., Stillwater, OK. The expert system has a Greenbug Economic Threshold Calculator, which will calculate a treatment threshold for greenbugs based upon data the user provides. It also allows the user to print Glance 'n Go sampling plans for the appropriate economic threshold that can be used to sample several fields using a single form. Treatment thresholds calculated by the expert system incorporate weather data to predict growth rates of the greenbug population, in addition to the price of insecticide treatment and the value of the crop. The expert system also has modules to help in insecticide selection, cereal aphid identification, and natural enemy identification.
