Abstract

High correlations between food consumption and excretion in terms of dry matter, calories, lipids, and nitrogen were obtained during the larval stages of Pseudaletia unipuncta (Haw.). The regression coefficients for this relationship in terms of dry matter did not differ significantly from those of calories; this leads to the hypothesis that the ratio of food consumption and excretion in terms of dry matter in a particular larval instar provides an estimate of caloric intake.
