    Description / Table of Contents: Summary By application of theBodenheimer's method, in taking 10°C for the threshold of the parasit development, the number of days/degrees necessary for a mean evolution ofProspaltella has been calculated. With this method, the theoretical number of generations is identical with that observed in several orchards of some countries. This method is suggested to facilitate the use ofProspaltella by fixing the time necessary to show the parasite's efficiency.
    Notes: Résumé Par application de la méthode deBondenheimer en prenant 10 °C pour seuil inférieur de développement du parasite, il a été calculé le nombre de jours/degrés nécessaires à l'évolution moyenne deProspaltella. Avec cette méthode, le nombre de générations calculé est identique à celui observé dans divers vergers de différentes régions. La méthode est proposée pour faciliter l'emploi deProspaltella en déterminant le temps nécessaire à la manifestation de l'efficacité.
