The effect of four different levels of infestation by the boll Weevil (Anthonomus grandis Boheman) on earliness, yield, and quality of cotton lint was evaluated in a replicated field-cage experiment at Stoneville, Mississippi, in 1958-60. Seasonal square (Hower-bud) infestation levels of about 0%, 25%. 50%. and 75% were used. As infestation level increased, plant fruiting was delayed, with a subsequent delay in time of harvest. Plots held at 0% infestation yielded the earliest cotton; those at the highest infestation level produced the latest harvestable cotton. Yield data indicated an inverse relationship between total yield And percentage of squares damaged throughout the season. grade indexes and lint values indicated no significant loss in quality of lint at the different infestation levels. Differences in value of lint per acre for the four treatments actually reflected differences in yield.
