用计算机建立数据库以研究病虫害及其天敌种群动态规律并建立预测和防治决策模型,这是计算机在农业方面开发的重要进展,是病虫害系统管理工作中不可缺少的环节之一。国外这项工作已进行多年,国内也已开展这方面的研究。生态学是害虫综合治理的基础,利用电子计算机来研究昆虫和天敌之间的关系,并建立数学模型和模拟模型。而数据库正是建立预测和决策模型的基础。我们首次把河北省杂粮害虫天敌的情况用计算机管理,为后续工作打下基础,也为该资源信息利用提供了编辑、统计、快速查询
The establishment of a database to study the dynamics of pests and diseases and their natural enemies, and the establishment of prediction and prevention and control decision-making models are important advances in computer development in agriculture. They are also one of the indispensable links in pest management. This work abroad has been carried out for many years, and research in this area has also been carried out in China. Ecology is the basis of integrated pest management. The use of electronic computers to study the relationship between insects and natural enemies, and to establish mathematical models and simulation models. The database is the basis for building predictive and decision models. For the first time, we used computer management of the natural enemies of grain pests in Hebei Province to lay a foundation for follow-up work and provided edits, statistics and quick inquiries for the utilization of this resource information
