Excerpt from Aerial Dispersal of the Pink Bollworm in the United States and Mexico: Production Research Report No. 96 Light traps have been used to detect the occur rence and dispersal of pink bollworm moths in many areas. Glick and Hollingsworth who operated traps in the lower Rio Grande Valley during the summer and fall of 1952, collected many pink bollworm moths; they trapped more moths in late August than in any other month. During one night (august immediately after cotton stalks in the area had all been destroyed, they collected an estimated pink bollworm moths. The following ni ht, the collected only and 8 days later Septem r 6) only 34. They concluded that because the cotton stalks had been completely destroyed, the moths had taken flight to another area more promising. Since at this time the prevailing wind was south southeast, they probably dispersed in a northerly direction. During the late summer of 1952, Glick and Hollingsworth (8) collected pink bollworm moths from light traps placed in the northeastern part of Texas; before this time the area had not been known to be infested. Their finding indicated that moths had migrated into the area. The moths were probably carried by the southerly winds from a heavy infestation on late cotton in the Corpus Christi area that was present in the fall of 1951.
