In the light of the present world food situation, the control of insects assumes a role of major importance in the agricultural program. Various insects, among which grasshoppers are one of the most notorious, attack our growing groups, upon which we depend for food. Others attack grains in storage; plant and animal products of many kinds; clothing and articles of furniture; and our domestic livestock. Man himself is not immune from attack as is borne out of by the epidemics of louse transmitted typhus which are today growing in extent in certain parts of Europe. The losses sustained by mankind due to the ravages of insects runs into a staggering figure every year. This report, however, is concerned solely with the control of grasshoppers, which in South Dakota alone have destroyed millions of dollars worth of cereal, forage and truck crops in each of the past several years. Mr. G.I. Gilbertson, South Dakota Extension Entomologist, gives the loss figure of $42,303,030 for the 5-year period of 1937-1941, inclusive.
