Abstract

Cyclophosphamide-induced conditioned suppression of cricket predation was observed in tasteaversion-prone (TAP) but not in taste-aversion-resistant (TAR) rates. These TAP and TAR strains had been selectively bred for efficient or inefficient acquisition of cyclophosphamide-induced saccharin taste aversions (TAs). Equivalent preconditioning cricket predation was practiced by nonfasted subjects of both strains. TAR rats that ate crickets before a cyclophosphamide injection were thereafter voracious predators as were saline-injected and pseudoconditioning controls of both strains. However, conditioned TAP rats subsequently displayed a marked suppression of cricket predation. Predation can provide a deprivation-free and species-natural consummatory response for studies of strain differences in TA conditionability of TAP and TAR rats. In addition, the present results indicate that TAP and TAR strain differences in TA conditionability are not restricted to the saccharin solution that was the conditioned stimulus basis of prior strain development.
