* indicates a significant difference at P = 0.05 level by Student’s t-test.
¹⁾ Mean values (± SE) in the same column at the same temperature that are followed by different letters differ significantly at the P = 0.05 level by the SNK test.
²⁾ One way ANOVA: F = 4.0, df = 2, P = 0.032 for 25°C; F = 4.4, df = 2, P = 0.0266 for 28°C.
³⁾ One way ANOVA: F = 2.4, df = 2, P = 0.114 for 25°C; F = 4.4, df = 2, P = 0.0304 for 28°C. Oviposition rate equals to the egg amount divided by adult longevity (eggs/day).
⁴⁾ One way ANOVA: F = 2.6, df = 2, P = 0.0974 for 25°C; F = 3.2, df = 2, P = 0.063 for 28°C.
⁵⁾ One way ANOVA: F = 1.8, df = 2, P = 0.1958 for 25°C; F = 11.4, df = 2, P = 0.0008 for 28°C.
