Abstract	Lygus hesperus (Knight) on cotton in the field were, on the average, distributed on the fifth through seventh nodes from the terminal. Most nymphs were located on squares, while the majority of adults were found on bolls. In comparison, adults on glasshouse plants were located predominantly in the upper four mainstem nodes; most were found on leaves. In the glasshouse, L. hesperus that were on fruit structures were almost entirely on squares. The difference in distribution between L. hesperus populations in the field and glasshouse appeared to be largely due to different plant growth patterns. Glasshouse plants were spindly, with a simple canopy characterized by short branches, few fruits, and relatively little vegetation. Plants in the field developed a full canopy, larger and more branches, and more fruit per branch, thus providing more habitat further down the plant for L. hesperus to feed. These results suggest that glasshouse experiments provide biased information on L. hesperus distribution and, possibly, feeding behavior.
