Note: Data are means ± SE. Different lowercase letters in each column (stage) denote significant difference in percent survival at different temperatures within that stage after analysis using Tukey’s test (P < 0.05). The F value is an indicator of ANOVA analysis, which usually compares the differences between groups. When the value of F is larger and the value of P is smaller, the result is more reliable. When P < 0.05, there was a significant difference between groups, when P > 0.05 or P = 0.05, there was no significant difference between groups. The letters df denote degrees of freedom.
