Abstract

Final instar larvae of fall webworms, Hyphantria cunea (Drury), were labelled to equilibrium levels on persimmon leaves containing 45Ca. Loss rates of 45Ca from the larvae were followed in the laboratory after either feeding larvae on unlabelled leaves, or starving other larvae.Initial loss-rate characteristics were different in the two feeding treatments, but biological half-lives were not significantly changed. Feeding shifts the time at which the lower loss-rate comes into effect.
