Abstract
Desert locusts, Schistocerca gregaria (Forskal), in Africa began to swarm in 1986, and through 1989 threatened to destroy crops in the Sahel, North Africa, the Arabian Peninsula, and southwestern Asia. The region had a long history of locust outbreaks but was unprepared for the magnitude and duration of the last plague. Efforts were aimed at protecting the crops rather than at stopping the plague at its points of origin. Factors that caused the plague's demise are identified, and strategic locust control for preventing or terminating future plagues is described and discussed. Integrated pest management, financial coordination, research, organizations specific to the task, effective logistical support, and international cooperation are essential to strategic control.
