Effects of low- and medium-sodium artificial diets on Pieris development

	Males	Females
Thoracic protein
Diet	t19 = 2.45*	t23 = 2.24*
Brain size
Diet	F1,4 = 0.41	F1,5 = 6.73*
Wing length	F1,4 = 0.57	F1,5 = 1.16

Shown are results from t tests and ANOVAs testing for effects of diet (low vs. medium sodium in an artificial diet) on thoracic protein (mass protein per mass dry thorax) and brain size. The model for brain size also included a measure of body size (wing length).
