Fig. 3. Mean (± s.e.m.) arrestment response of T. basalis females exposed to four consecutive arenas at intervals of 1, 23, and 72 h treated with residues of N. viridula females (solid lines; experienced females) and T. basalis females tested at the same times (stippled bars; naive females). Means represented by lines and indicated by the same letters were not significantly different by ANOVA repeated measures followed by Tukey's test for multiple comparisons. Means represented by bars were not statistically different by one-way ANOVA. Vertical dotted lines indicate means that differ significantly based on t-test (ns P>0.05, ^**P<0.01, ^***P<0.001).
