Abstract

During the spring and summer of 1931 there occurred in south-central South Dakota and northeastern Nebraska the most serious grasshopper outbreak recorded in the United States since the days of the Rocky Mountain locust. The almost complete destruction of all cultivated crops over an area of thousands of square miles in extent, ranks this outbreak as one of the most serious insect plagues which has ever confronted the farmers of the West.
