In order to meet the diagnosis and control of aphids against the problem of expert system requirements, Considering the characteristics and requirements of diagnosis and prevention of aphids diseases, a case-based reasoning apply to diagnosis and prevention of aphids diseases. The description and search mechanism of diagnosis case are illustrated in detail. A hybrid reasoning method integrating case-based reasoning and rule-based reasoning is presented with totally new viewpoints, the structure of the expert system is discussed, various modules and a detailed exposition, the ultimate example of a demonstrated example of the process. The system in practical application is a good result.
