Abstract: Traditional field experiment of integrated pest management of maize has several problems, such as long-time consumption, too many experiment steps and high cost, greatly affected by the environment, the experiment teaching content can not be standardized. In order to solve these problems, a virtual simulation experiment of integrated pest management of maize was constructed. The experiment consists experiment preview module, experiment operation module, experiment test & report module and experiment database module. The experiment can simulate the control of three diseases and eight pests of maize during maize’s five key growth stages. This virtual simulation experiment makes up for the shortcomings of traditional experiment, improves education effect and talent training quality. This experiment also provides reference for the construction of similar virtual simulation experiment.
