The activity and sensitivity of acetylcholinesterase (AChE, EC 1.1.1.7) from an organophosphate-susceptible (OSS) and three resistant (OR-0, OR-1 and OR-2) strains of the greenbug (Schizaphis graminum) were biochemically compared. All three resistant strains displayed higher frequencies of individua

The Type II esterase associated with organophosphate resistance in the greenbug, Schizaphis graminum, was purified by column chromatography and preparative electrophoresis resulting in over 100-fold purification and approximately 11% recovery. The native enzyme appears to exist as a heterodimer with
