A method to determine erythrocyte cholinesterase (ChE) activity was modified for use in wild mammals. Erythrocyte ChE of California voles (M icrotus califomicus) was primarily acetylcholinesterase (AChE), which was similar to the brain and unlike plasma which was primarily butyrylcholinesterase (BChE). Triplicate erythrocyte AChE analyses from individual animals of several species of wild rodents revealed a mean coefficient of variation of 8.7% (SD = 4.3%). Erythrocyte ChE activity of several wild mammals of California revealed that mule deer ( Odo coileus hemionus ) had the highest erythrocyte AChE activity (1,514.5 mU/ml) and dusky-footed woodrats ( Neotoma fusci pes ) had the lowest activity (524.3 mU/ml). No ChE activity was found in erythrocytes of several species of birds and fish.
