The relationship of the factors irrigation (both overhead and seep) and pesticide residues (and their interaction) on attempted dispersal of spider mite on greenhouse-grown peanuts was determined. Pesticide residue had no measurable effect on mite movement; however, irrigation method had a marked influence on mite attempted dispersal. Mites moved more on leaves of plants receiving seep irrigation than those receiving overhead irrigation.
