The cotton fleahopper, Pseudatomoscelis seriatus, is an early-season pest which can severely limit cotton production by feeding on plant terminals and immature fruiting structures. Previous research has indicated that fleahoppers disperse from early-season weeds when these plants become unsuitable hosts. However, more information is needed about the role of atmospheric factors in the temporal patterns of fleahopper dispersal. A second-year field study was conducted to examine temporal patterns of early-season fleahopper dispersal from turnipweed (Rapistrum rugosum) and other weed hosts as determined by captures of fleahoppers on sticky traps. Atmospheric variables were measured by automated weather stations located at four trap sites in the Brazos Valley of Texas in 2005. Results will be presented that will aid in the decision-making process for cotton fleahopper management.
