Results Development of insects reared in laboratory The linear mixed-effects model applied to the morphometric data confirmed a highly significant effect of the developmental stage ( F = 4323.5, p < 0.001) and the interaction between stage and generation ( F = 1.6, p < 0.001) on insect weight, with similar significant results for all other morphometric variables (length, width, and area).
