Abstract
Pyrethroid insecticides have been divided into Types I and II based on behavioral profiles of toxicity produced by life-threatening dosages. In order to assess potential alterations in acquired (operant) behavior, acute dosage-effect and time-course determinations for permethrin (Type I) and cypermethrin (Type II) were made. Long-Evans rats responded for food according to a multiple schedule consisting of four different variable-interval schedules. Permethrin (100-400 mg/kg) and cypermethrin (7.5-60 mg/kg) were administered po 1.5 hrs pre-session and their effects on response rates and between-component response patterning determined. Differential effects on response patterning, in potency, and in the time course of effects of permethrin and cypermethrin suggest a type-specificity for pyrethroid effects on schedule-controlled behavior at dosages far below those producing lethality in rats.
