Show 1937] Sorenson, Knowlton: 'Grasshopper Survey in Utah, 1936 177 of information obtained in the 1936 surveys, either threatening or severe in festations of grasshoppers are likely to occur during 1937 in the localities in dicated in Table 4. Moderate to severe damage is likely to occur in a number of the localities underlined in Figure 1. Based upon 1935 values of various Utah farm crops published by the U.S.D.A. Bureau of Agricultural Economics, Division of Crop and Livestock Estimates, it is estimated that the total damage to crops in this state due to grasshoppers approximated $2,500,000 in 1936. In anticipation of grasshopper control in Utah during 1936, 130 tons of poisoned bran bait was made available to counties, growers' organizations, or individual farmers, at cost, through the cooperation of the United States De partment of Agriculture Bureau of Entomology and Plant Quarantine, the State Department of Agriculture, and the Utah Agricultural Experiment Sta tion. Although less than half of this bait was used in 1936, all of it could have been advantageously used. Based upon replies to questionnaires sent to County Agents together with information obtained from farmers in hopper infested districts, it is estimated that the value of farm crops saved during 1936 by use of grasshopper bait was approximately $15,000. In a few dis tricts of the state droves of turkeys with as many as 5000 birds in each, were ranged over hopper-infested land with the result that the insects in these districts were largely destroyed. At Paragonah, Parowan, and in the Indian Creek district of San Juan County, where grasshopper infesations were particularly severe during 1936, it was observed that grasshoppers were being diseases. destroyed by fungous Errata.-" Grasshopper Survey in Utah, 1935."
