Desert locust
The desert locust (Schistocerca gregaria) is a species of locust. Plagues of desert locusts threaten agricultural production in Africa, the Middle East, and Asia. They have done so for centuries. The livelihood of one-tenth of the world’s human population may be affected by this voracious insect. The destructive swarms of locusts do not form every year, but only when conditions are right for them.
