Results of analysis of variance (ANOVA) on the development time data obtained from the assays done under constant light (LL), light/dark (LD) and constant dark (DD) conditions. In the ANOVA design, population (P), light regime (L), sex (S) and window of egg collection (W) were used as fixed factors. Statistically significant values (p < 0.05) are shown in bold.
