The passage of a 14C-labeled carbamate, 2-(2-chloro-1-methoxy-' ethoxy)phenyl N-methylcarbamate, or its labeled metabolites through the alimentary system of the grey garden slug Deroceras reticulatum was examined by autoradiographic studies and scintillation counting. It was demonstrated that, in a first step, the molluscicide penetrated the cells of the oesophagus and the crop. It was quickly transported by the hemolymph to the periphery of the body and re-entered the cells of the digestive tract and the mid-gut gland in a second step from the hemolymph side. The crypt cells of the mid-gut gland are discussed as cells involved in detoxification, and connective tissue cells as the major storage sites of the labeled material. Excretion in feces and secretion in mucus are thought to be the routes of 14C elimination.
