Table 2.
Survival, development time, live and dry weight, dry matter (DM) content, and fat content of house crickets, lesser mealworms, and black soldier flies on a control diet (0%) and diets enriched with 1%, 2%, or 4% of flax seed oil (mean ± SD; n = 6). If for a species superscripts in the same column have no letters in common, means differ significantly (ANOVA followed by Tukey's HSD; P < 0.05)
