title: The excretion of urea by the larvae of Spodoptera mauritia Boisd. (Noctuidae: Lepidoptera) during development.
abstract: The concentration of urea in the excreta of the 6th instar larvae of Spodoptera mauritia varies from 4.017 +/- 0.541 to 31.052 +/- 1.193 mumoles/g dry excreta (mean +/- SE). The observation confirms that urea excreted is of metabolic origin.
