Rural population reaches third four of the national population. Information has been recognized increasingly by people as resource of paramount importance to social and economic development in China. IT is an integration of computer science, communication technology, networking technology and sensing technology, and featuring Internet in the information age. Its aim is to develop and use information and software technology in solving problems posed from agriculture, a major part from plant protection. For enhancing vegetable pest management we have developed an array of databases, expert systems and GIS and are managing for their integration as decision supporting systems.
China is tremendously vast in territory and strikingly diverse in meteorology and biogeography.
So, agricultural software products, such as databases and expert systems, must be developed specially for local use. According to our experiences, we might develop such a product firstly as a prototype or platform, then localize it for its use in the new target region. These databases, expert systems and GIS are used mainly in Beijing and its surrounding area in north China now. Obviously, they should be forced into their localization for south China or west China, if needed. CN-VegePest , a database consists of about 200 species as vegetable pest insects distributing in Beijing and over north China.
