Grasshoppers did an immense amount of damage to farm crops in South Dakota in 1930 and 1931. If weather conditions are favorable during the coming winter and next spring, there is every reason to believe that 1932 will be another grasshopper year, but with the damaged. territory considerably enlarged over that of 1931. A survey has shown that there are large numbers of grasshopper eggs in the soil. At the present time in those areas where the grasshopper damage was severe during the past summer, while in the remainder of the State the number of eggs in the soil is, at times, sufficiently abundant to cause alarm. The natural enemies that feed on or within these eggs are not abundant this fall, and, therefore, every effort should be made by the farmer to destroy as many of the grasshopper eggs as possible.
