In the first large-scale tests with sprays of chemosteri- ants against any insect pest, apholate applied to the cotton in 211/2-acre screened cages at rates of 1, 2, or 4 pounds per acre for control of Anthonomus grandis Boheman suppressed populations compared with an untreated check whether the initial infestations were begun with virgin or mated pairs. Hell1pa, at a rate of 2 lb per acre, was ineffective. At 4 lb per acre, apholate reduced production of squares compared with an untreated check, but the toxicity of this compound was too great for general use. Since the technique proved effective, other less hazardous chell10sterilants arc being sought.
