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
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
