Abstract
Adults and nymphs of Lygus hesperus Knight and L. elisus Van Duzee were found to be distributed in cotton fields in clumped, nonrandom patterns. The nymphs showed more clustering than the adults. The adults and nymphs were consistent in their degree of clumping between 8 AM and 6 PM. The observed distribution patterns were fitted by several contagious mathematical models. Statistical analyses indicate the feasibility of using theoretical distributions to describe samples based on adult-plus-nymph or adult-plus-twice-nymphs counts.
