Abstract

A method for weekly production in excess of 100,000 second-instar larvae of the spruce budworm, Choristoneura jumiferana (Clem.), is described. It depends on adherence to specific regimes of physical conditions and manipulation for the different immature stages. Standard, easily obtained utensils and materials are used in the rearing technique.

Résumé

Exposé d’une méthode permettant de produire jusqu’à plus de 100,000 larves du 2e âge de la Tordeuse des bourgeons de l’Epinette Choristoneura jumiferana (Clem.) par semaine. Cette méthode repose sur l’observance stricte de régimes spécifiques de conditions physiques et de manipulation aux différentes phases de développement. C’est une technique d’élevage utilisant des ustensiles et des matériaux ordinaires et faciles à obtenir.
