Fig. 4. Relative abundances of the six isoforms of Tnt in the fall armyworm moth in relation to total mass (body+added load) and larval feeding treatment (fully fed versus fed 2 days then starved). Lines in the large plot show individual regressions for each of the four treatment groups for the most abundant isoform, Tnt F. Smaller plots show effects of total mass (solid lines) or nutrition (dashed lines for Tnt D at total mass >100 mg) in the remaining five isoforms.
