Probably more attempts have been made to estimate boll weevil, Anthonomus grandis Boh., losses accurately than have been made in the ease of any other insect. Such estimates have been made by entomologists, crop reporters and commercial organizations. By far the most accurate estimates have been found to be those made by entomologists. A very accurate estimate can be made by comparing production on plots treated with calcium arsenate and on plots untreated. The difference in production is a precise measure of the amount of damage caused by the weevil. The usefulness of this method could be greatly increased by test plats provided by state entomologists in different parts of their states. Estimates made by crop reporters have been found to show a strong trend toward exaggeration. Those made by commercial organizations are frequently colored by market conditions.
