highly significantP <0.0001
ANOVA on the proportion of nymphs that settled and presumably fed on each site (midrib or secondary veins, on upper or lower sides of the leaf) indicated that differences between healthy and LAS-infected leaves were not significant ( F = 0.02, df = 1248, P = 0.88), whereas those among various sites were highly significant ( F = 25.7, df = 3248, P <0.0001).
