Different letters within a column indicate significant differences between treatments (α = 0.05), ANOVA followed by Tukey’s HSD (honest significant difference). 1n = number of replicates per treatment. 2 Larvae were fed the standard diet (10 g of dry Gainesville diet + 17 mL of water) following the methods described by Tomberlin, Sheppard and Joyce [33].
