Abstract
Two cholinesterases were identified in the cotton bollworm Helicoverpa (Heliothis) armigera Hbn., that is, acetylcholinesterase from the nervous chain and butyrylcholinesterase from homogenates of larvae. A comprehensive study of the substrate-inhibitor specificity of cholinesterases (based on the modern concept of inhibition by high substrate concentrations), as well as the investigation of anti-enzyme action of 57 irreversible organophosphorus inhibitors, indicated a peculiarity of the enzymological characteristics of the bollworm cholinesterases compared to cholinesterases of arthropods and some mammals.
