Tryptophan Metabolism in Rice Moth Larva (Corcyra Cephalonica St.)

Abstract
The presence of kynurenine and 3-hydroxykynurenine and the absence of xanthurenic acid in the excreta of rice moth larvae (Corcyra cephalonica St.) fed a pyridoxine-deficient but tryptophane-supplemented diet were demonstrated by circular paper chromatography.
