Abstract
Sequential sampling plans based on the binomial distribution were developed for sampling squares (floral buds) damaged by the boll weevil, Anthonomus grandis Boheman, or the bollworm, Heliothis zea (Boddie), and the budworm, H. virescens (F.). These plans were compared to a fixed-sample-size (100 squares) method of sampling damaged squares. Field trials indicated that the use of sequential sampling plans provided ca. 50% savings in time over the fixed-sample-size method. The treatment decisions were similar for both methods.Keywords
