The effect of methyl parathion on susceptibility of bobwhite quail (Colinus virginianus) to domestic cat predation

摘要: Bobwhite quail (Colinus virginianus) that received either 0, 2, 4, or 8 mg/kg methyl parathion (O,O-dimethyl o-p-nitrophenyl phosphorothioate) treatment were investigated as to their susceptibility predation by a cat (Felis domesticus) predator. Four hours after receiving (MP), physical activity levels monitored in and included the number of seconds spent still, walking, running, flying before was introduced into an experimental arena. The cholinesterase (ChE) for each on experiment determined. Quail captured exhibited significantly greater inhibition brain ChE more time being still than noncaptured birds. Birds MP at those other groups had reduced 42.8% normal activity. There tendency increasing be susceptible capture neurological behavioral effects may have important ecological ramifications.
