Abstract: This paper reviews the present status of control techniques and management strategies for locust and grasshopper plagues throughout the world. The discussion focuses on monitoring and forecasting, chemical control, biological control, IPM strategies, research direction,and so on. The similarities and differences in management strategies and control techniques for locusts and grasshopper plagues between China and overseas were compared. It was concluded that there are many similar problems and requirements for controlling locust and grasshopper plagues in China and abroad, for instance, environmental protection, economics and politics, biodiversity conservation, monitoring techniques, and biological control. Research and overseas experience shared are of tremendous benefit to the sustainable management of locust and grasshopper plagues in China. In general, there are six essential aspects in developing an IPM approach to controlling locust and grasshopper plagues: (1) emphasizing prevention strategies; (2) taking the basic research on biology and ecology seriously; (3) implementing and improving forecasting and monitoring technologies with Geographic Information System (GIS) and Remote Sensing (RS) techniques; (4) exploring novel and environmentally benign locust-control technologies; (5) evaluating novel and existing control technologies for their environmental impact and efficacy; and (6) organizing coordinated activity in all regions where locusts and grasshoppers should be controlled.

Key words: locusts, grasshoppers, management strategy, control technique
