Abstract: The main reasons for the outbreak of grassland grasshopper are discussed in this research and controls by sustainable management countermeasures are considered. Global climate warming, drought, regional climate abnormity, food resources, intra and interspecies competition, environmental factors together with methods and utilization of grasslands may all affect grasshopper population dynamics and contribute to the outbreak of grasshoppers. Ecological safety, economic availability and sustainable development of grassland systems are regarded as three guidelines for management of grasslands. More technical research on monitoring and forecasting grasshopper outbreaks is needed to deal with the current severe disaster caused by the grasshoppers. Measures for better management of grasslands should play a more important role in controlling the grasshopper populations. New management methods should be further explored and the range and force of biocontrol be extended, as well as new chemical control technology be established. Only through the adoption of those measures can the goal of sustainable management of grassland grasshopper be achieved.
