  1. Results of analysis of variance (ANOVA) on the development time data obtained from the assays done under light/dark (LD) and constant dark (DD) conditions. In the ANOVA design, population (P), light regime (L) and sex (S) were used as fixed factors, whereas replicate or Block (B) was used as random factor. In all cases the replicate means were used as the unit of analysis and hence, only the fixed factor could be tested for significance. Statistically significant values (p < 0.05) are shown in bold.
