Fig. 5. Linear regression analysis of (A) body mass and (B) feeding vs combined hexamerin-1 and -2 protein abundance. The regression shown in A, which is not significant, indicates no relationship between body mass and hexamerin abundance. Alternatively, the regression shown in B of feeding vs hexamerin abundance is significant (P<0.05). Note also that the two highest feeding amounts recorded were in each of the untreated controls at assay day 15; these treatments had high hexamerin levels and no presoldier differentiation.
