Significant differences in propensity to attempt oviposition into various types of fruit were found among Mediterranean fruit flies, Ceratitis capitata , from the same wild population. Evidence presented suggests repeated exposure to one host fruit type conditions females to that host, and influences female response to other hosts in future encounters. Reversibility of conditioning was also demonstrated. Learning to refuse a novel host type is indicated as being more important than learning to accept a familiar host type in medfly conditioning to hosts. RÉSUMÉ Importance de l'apprentissage dans le choix du lieu de ponte par Ceratitis capitata Dans la même population sauvage de C. capitata , on a observé des différences significatives dans la tendance à essayer de pondre dans divers types de fruits. Les faits rapportés suggèrent qu'un apprentissage pendant la ponte sur un type de fruits conditionne la femelle à cet hôte, et influe sur les réponses de la femelle à d'autres hôtes lors de rencontres ultérieures.
