Feeding preference of H. assulta with different feeding experiences in dual-choice assay. Columns in (A), (B) and (C) represent the mean areas + SE of plant leaf disks consumed by caterpillars with different feeding experiences. Mean areas were compared by employing one-way ANOVA followed by Scheffé’s Post-Hoc test (P < 0.05). Columns having no lower case or capital letters in common differ significantly (P < 0.05). Columns in (A)’, (B)’ and (C)’ represent mean + SE of the preference indices for the 5th instar caterpillars with the indicated feeding experience. Preference indices were compared in caterpillars with a certain feeding experience by employing the paired-sample t-test (P < 0.05). ‘*’ and ‘**’ represent the difference was significant at 0.05 and 0.01 level, respectively. ‘ns’: no significant preference different (P > 0.05).
