none The venom gland of the braconid parasitoid, Apanteles kariyai, was morphologically observed with photomicroscope and aromatic amino acids in its venom fluid were chemically analyzed with a three-dimensional HPLC system-coulometric ECD. Tyrosine (TYR-4) fwdarw tyramine (TYRA) fwdarw hydroxyphenylacetic acid (HPAC-4) and tryptophan (TRP) fwdarw kynurenine (KYN) were the detected metabolic pathways. This report of venom components of a braconid wasp outlines qualitative differences between this and venom from social wasps.
