Effects of dieldrin on operant behavior of bobwhites.
Bobwhites (Colinus virginianus) were trained to peck a green lighted key to receive food. Bird response performance was monitored for 14 days, then birds were dosed with five levels of dieldrin (50 to 300 micrograms every other day) for 42 days while their response performance was monitored. At the end of the 42-day dosage period, mean brain concentrations of dieldrin ranged from 2.6 ppm to 11.8 ppm; lower concentrations associated with lower dosage levels. All dieldrin dosage levels altered cage behavior of bobwhites, dieldrin dosage levels greater than 100 micrograms resulted in slower and less accurate responses by dosed birds during the 42-day trial period.
