Cereal aphids expert system (CAES) Identification and decision making

This paper describes the development of an expert system designed to provide identification and information to farmers and extension specialists as well as information for educational and research purposes, on the main cereal aphid species in Spain. The program has a graphical support system which helps a non-aphid specialist to obtain an accurate identification. The information that the system provides is aphid appearance, life cycle, host plants, damage, injury level, control measures, additional information and references. The system is currently running in Videotext, allowing for consulting via telephone lines throughout Spain. © 1993.
