Effect of temperature on daily mortality rate for each period. (P1: from fertilization to hatching; P2 from hatching to emergence; P3 from emergence to first food intake). Differences obtained by the post-hoc Tuckey test were considered significant at P < 0.05. The same letter indicates no significant difference between temperatures in each of the three stages.
