title: Presence of 5-hydroxy-indolacetic acid in Diloboderus abderus larvae without monoamine-oxidase-like activity.
abstract: The authors confirmed the presence of monoamines and 5-hydroxy-indolacetic acid (5-HIAA) in the cephalic region of Diloboderus abderus larvae employing a high pressure liquid chromatography (HPLC) with electrochemical detector. An anticholinesterase insecticide produced an increase in the serotonin and 5-HIAA endogenous levels, and did not modify the catecholamines. Monoamine-oxidase activity was undetectable with a radioactive method using 3H-tyramine as substrate.
