ABSTRACT

Since 1992 the boll weevil has become a newly established economic pest to cotton production on the Texas High Plains. The present boll weevil problem in Texas High Plains counties is believed to result from two major factors: an unprecedented five successive mild winters and the establishment and maturation of CRP (Conservation Reserve Program) grass acreage. The objectives of these studies were to sample and compare various habitats for overwintering boll weevils and determine the range of weevil overwintering. Habitats sampled consisted of the ground-trash (leaves, stems, debris, etc.) along with approximately a quarter inch of loose soil. Samples were processed and examined visually for adult boll weevils. Boll weevils are able to overwinter successfully on the High Plains of Texas in a number of habitats. Tree litter appears to be a primary habitat for boll weevils to overwinter but CRP acres may be the most important habitat on the High Plains of Texas.
