Several reports (Gaines 1937; Moreland 1938; Moreland & Bibby 1931) have been published recently in the JOURNAL OF ECONOMIC ENTOMOLOGY concerning the control of the bollworm, Heliothis obsoleta (F.), as progress reports of the cooperative project between the U. S. Department of Agriculture, Bureau of Entomology and Plant Quarantine, and the Texas Agricultural Experiment Station. The results of these tests have shown that dusting with calcium arsenate at the rate of about 8 to 9 pounds per acre gave the most effective and economical control of this pest. Additional tests in connection with this project were made by the senior author in 1936, and the analysis and interpretation of the data were made by the junior author. The work was conducted in the Brazos River Bottoms. The purpose of the project was to determine the comparative effectiveness of the following insecticidal dusts: calcium arsenate, calcium arsenate plus 5 per cent Paris green, calcium arsenate plus 10 per cent Paris green, calcium arsenate plus cube (containing 0.8 per cent rotenone), calcium arsenate plus pyrethrum (containing 0.09 per cent pyrethrins I and II), calcium arsenate plus 50 per cent lime, and calcium arsenate plus 50 per cent sulfur.
