The writer and many growers have observed that the greatest prevalence of kernel- spot OA^er large areas is found in or near orchards where cow- peas are growing. It is a common practice of the pecan gTOwers throughout the southern United States to plant cowpeas between the tree rows to be used either as hay or plowed under as a cover crop. When the hay is harvested or the i^ea vines die down natu- rally the bugs, if present, will migrate to the pecan nuts, often in great numbers. Frequently kernel-spot will be found in great abundance on ntits that have grown in close proximity to gardens where tomatoes, okra, or other host plants are present. This is especially noticeable in orchards where some crop other than cow- peas has been Fig. 4.—Type of cage used for confining insects with Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
