Book excerpt: Excerpt from Investigations in Control of Hemipterous Cotton Insects in Arizona by the Use of Insecticides, Vol. 65535: July 1940 In addition to the direct injury to the cotton, a secondary source of trouble consists of the dissatisfaction among the cotton pickers in fields which have been heavily damaged by hemipterons insects. The cause of the trouble is the sticking of the lint to the proliferations within the punctured bolls, augmented by the tendency of badly punctured bolls to Open only partially. So that undue effort is required to pick the cotton from them. These punctured bolls often require several pulls, while in a clean, unpunctured boll the lint can usually be gathered with a single motion of the hand. Since in damaged fields the amount of cotton a picker can gather is determined largely by the percentage of punctured bolls, the pay is correspondingly reduced. This aspect sometimes assumes serious pro portions, the pickers migrating from camp to camp in an effort to locate clean cotton fields.
