Abstract

The authors, members of the IOBC working group on genetic control of the European cherry fruit flyRhagoletis cerasi L., present the summarized results of a joint 4-year experiment aiming at the optimalization of storage conditions for stockpiled pupae. Highest emergence rates are achieved by chilling periods of 5 to 6 months and recommended storage temperatures are close to the developmental threshold of +5°C. Total storage time of pupae should not exceed 14 months.

Résumé

Les auteurs, membres du groupe de travail de l'O.I.L.B. sur la lutte génétique contre la mouche européene de la cerise,Rhagoletis cerasi L., présentent le bilan de 4 ans d'expérimentation en commun en vue de trouver la meilleure méthode de conservation des pupes. Les taux d'émergence imaginale les plus élevés sont obtenus à la suite d'une période de froid de 5 à 6 mois à une température voisine du seuil de développement: 5°C. La durée totale de la conservation au froid des pupes ne doit pas dépasser 14 mois.
