Abstract
Spider mite population growth and dispersion patterns in field corn were analyzed over three growing seasons in the Texas High Plains. Infestation loci were distributed randomly during the early season, suggesting that fields were initially infested by windborne spider mites. Taylor's power law and Iwao's regression models indicated that spider mites were aggregated throughout the corn-growing season; Green's coefficient showed that the level of spider mite aggregation decreased during this same time. The potential for binomial sampling of spider mites was investigated.
