The uric acid method gave accurate and reproducible estimates of consumption and percent utilization by H. virescens and A. velutinana larvae. The results obtained by the uric acid method were compared with those obtained by the gravimetric method. The two methods also were used to compare the consumption and percent utilization of diets containing either L-methionine or D-methionine. The results obtained with A. veluitinana indicated that there is no difference in consumption and percent utilization of diets containing the 2 methionine isomers. However, H. virescens showed a significant difference in approximate digestibility of the 2 methionine isomers.}, number={3}, journal={ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA}, author={CHOU, YM and ROCK, GC and HODGSON, E}, year={1973}, pages={627–632} }
