Means comparisons of five δ 13 C EAA (ile, leu, phe, lys, and val) for wood-fed larvae and host tree in the A. glabripennis larvae: red maple feeding group, and for artificial diet-fed larvae and artificial diet in the A. glabripennis larvae: artificial diet feeding group
| A. glabripennis larvae: red maple experiment | δ 13 C EAA (±SE) (‰) |
|---|---|
| Red maple | − 28.9 ± 0.3a |
| Wood-fed larvae | −25.4 ± 0.4b |
| F (1,68) = 48, P < 0.0001 | |
| A. glabripennis larvae: artificial diet experiment | δ 13 C EAA (±SE) (‰) |
| Artificial diet | −26.8 ± 0.2a |
| Artificial diet-fed larvae | −25.1 ± 0.1b |
| F (1,34) = 78, P < 0.0001 |
Shown are mean values for three replicates per larval group, four replicates for red maple tree (bark + wood), and one replicate for the artificial diet control. Different letters represent a statistically significant difference at P < 0.05 within each feeding group.
